Do Cars Really Explode Like The Movies? DEBUNKED czcams.com/video/1iEBC-I0vbs/video.htmlsi=eRxIIYfVZ0CgQuXP
I think that the clearest way to explain WHY defibrillation is not used to treat asystole (flat line in all leads, but usually only checked in two leads [assuming the medical professional understands that a flat line sometimes appears in one lead and SHOULD be checked for, because asystole is not very responsive to treatment]) is to explain that defibrillation CAUSES asystole - that is the way defibrillation "works".
The "shockable" medical problem is that there is too much ineffective contraction going on in the heart muscle. It is in need of a "reset", as you mentioned. The way to reset the heart is to CAUSE asystole. The reason this is so effective is that cardiac muscle, unlike other muscle in the human body, is capable of causing its own contraction (depolarization).
By electrically overwhelming the heart muscle with a current that is large enough to move through the heart depolarizing all of the cells, but not large enough to cause a lot of damage to the conduction system of the heart (different doses are used in different settings), all of the heart muscle cells are expected to be depolarized at the same time, which SHOULD result in all of the heart muscle cells then repolarizing at the same time.
It is hoped that this will result in the heart's pacemaker (the part supposed to be in charge of its conduction system) spontaneously producing an organized heartbeat - just as it has thousands of times every day before in that person's life. Before the shock, the pacemaker was not in control of the heart beats.
People are appropriately shocked when they have a pulse, but it is technically not called defibrillation, even though it IS defibrillation. The terminology used is "synchronized cardioversion". The defibrillation is timed to NOT land on the T-wave of the electrocardiogram (the squiggly lines on the monitor during an organized rhythm). The T-wave is the repolarization, so the monitor is supposed to "synchronize" on (be timed to land on) the QRS complex, or the R-wave [Q-wave, R-wave, and S-wave make up the QRS complex] or the "depolarization" waves/complex). Cardioversion is just another word for defibrillation, so it is a "synchronized" defibrillation.
The rhythms that are appropriately treated with synchronized cardioversion are those that are too fast to be able to maintain life for long, because the heart is beating too quickly to pump blood effectively. This is determined by the effect on the patient, not by any particular "too fast" number. When Buzz Aldrin was landing on the Moon, an ECG of his heart rhythm looks like 400 beats per minute. This is probably due to the paper moving at half the normal rate during recording, so it would make the heart rate seem twice as fast as it actually was.
roguemedic.com/2013/05/what-does-a-moon-landing-ecg-look-like/
For many people, a heart rate of 200 would cause them to lose consciousness, have their BP drop to a very low level, and cause other signs of inability to maintain life. Fortunately, the rhythm is usually a "sinus tachycardia" - "tachycardia" is just a technical term for very fast (usually over 100) and "sinus" (or sinus node) is the name of the usual pacemaker of the heart. Since this is a sinus tachycardia, shocking it will not make things better . Sinus tachycardia is due to a problem that is NOT fixed by a shock. However, Ventricular Tachycardia (VT or VTach) and SupraVentricular Tachycardia (SVT) are examples of pacemaker problems that may be best treated by a shock. The rhythm being shocked often responds well to the shock, but the patient should be sedated, if they are conscious (anyone who tells you otherwise does not understand [or does not care - or both] what it is like for the patient to be shocked while feeling the shock. Competent medical professionals CAN (and DO) SAFELY sedate unstable patients for cardioversion.
Apologies for the long comment, but it is a lot more complicated than most people realize.

How is this video more clear and informative than what we are shown at school?
Seriously, I bet those movies are literally killing people by altering the judgement of the audience in real situations.
note, it’s quite common to see very small/small fibrillation waves on a ECG(heart trace) in cases of cardiac arrest, this is rarely mistaken as a flatline(asystole) and this MUST be treated with a defibrillator as soon as possible, since the heart is quivering and not stopped
ok
ok
You mean ventricular fibrillation
Dawg there are two shockable rhythms v-tach and v-fib and neither look like asystole (technically you can shock for SVT but that’s cardioversion and SVT also doesn’t look like asystole)
Its called fibrillation... which is why you use a defibrillator lol self explanatory
Interestingly that a scene in Flatliners remake actually involved one character saying that they can't shock the heart back to beating if there's no rhythm, they instead administered drugs, which is the correct way to actually deal with asystole.
Epinephrine iv or io
Great video and fairly accurate. I was a first responder where I worked and part of our CPR training dealt with the use of an AED. They are pretty foolproof when it comes to use. The ones we trained on had voice prompts which would guide the operator in the placement of the pads and operation of the device. Once the electrodes were placed properly, it would check for a pulse and if it detected one, it would not shock the patient. However, if a pulse was absent, it would start to attempt defibrillation at the lowest energy level. If normal rhythm was not restored, it would announce it was increasing the level and try again. The device would escalate the procedure up to 4 times at increasing energy levels. At the end of the cycle, if no pulse was present, it would tell the operator(s) to begin CPR. Incidentally with regards to CPR in movies and TV shows it never ceases to amuse me how phony the depiction is. Rarely do they correctly place the palms over the sternum and the compressions are obviously fake. The compressions have to be deep and usually will end up breaking ribs. Maybe you could debunk CPR in popular media.
As a first responder, you're the person I need to ask this: My husband was a victim of cold water drowning. He was trapped underwater for 14 minutes. It was defibrillation that brought him back. How could he be underwater for 14 minutes and not be flatline? I know cold water drowning (Isle of Man, if you're interested) is different. Was he not flatline after all that time?
@@tkmccoywv During training the instructor explained that the way a defibrillator worked was by clamping the heart with a direct current charge across the chest. During fibrillation the heart muscle loses it's rhythm and is essentially just quivering. Clamping the heart muscle stops the heart from quivering with the hopes that once the charge stops the heart will resume normal rhythm. It is not 100% effective. I am not sure whether it is effective or not in restoring heart function to a heart that has stopped beating altogether. That would best be answered by a cardiologist. I'm glad to hear that your husband life was saved.
@@johnbrandolini2915 Thanks John! I appreciate you taking the time to answer my question 😊
I love this channel. Unfortunately still very underrated, definitely needs more views for the work they put into videos.
The use of an AED was coverd in basic medical training and CPR
And one of the first things they said is it cannot stop a flatline, the device will detect it and not apply a shock.
You can only use a defibrillator in 2 out of many different types of arrhythmia. In case of flatlining, you can only use CPR and not defibrillators. Flatlining usually has a success chance of 0.1%, and it depends on overall youth and health of the patient. It is considered successful if the patient is still alive a month after the CPR has been performed.
I knew before I saw this video that the defibrillator was used to actually stop the heart from shaking hence the name defibrillator de =to stop and fibrillation= shaking/ jelly used when the heart is in a condition known as VF ventricular fibrillation or shaking of the ventricles
i love the humor put into these videos just seems to hit all teh right buttons keep it up
Well, Battlefield got one thing right when you can kill with the defibrillator
Aha, was trying to think of a video game example! Well done 👍
My brain manifested the image of a medic with a defibrillator in ww1
Everyone who can should learn CPR. ❤❤❤ I think it should be a free course, everywhere.
I think 99.9 percent of CPR courses are free. But yes, they need to be offered and promoted more.
@@DashingPartyCrasher lol that's what happens when a person only takes certified CPR courses, for my job. I assumed they all cost. 😄 Thanks for letting me know.
Awesome job guys!
Just a few notes:
- Defibrillators don't start or restart the heart - they actually stop the heart's erratic rhythm in order to persuade the heart's "natural pacemaker" to take over again.
- It's incredibly rare for someone to convert from an arrhythmia with pure defibrillation.
- There are only two shockable rhythms, called VT and VF.
- Almost every hospital and EMS agency worldwide stopped using defibrillation paddles nearly 20 years ago. It's purely depicted in shows because they look cooler than the adhesive pads we use now.
Love all your presentations Stu - informative and entertaining. 👍🙏
Thank you, sadly we've had to unlist this as it's been age restricted for some reason. We'll re-release soon hopefully once it's been sorted out.
This was a fascinating topic, thanks for posting!
Thanks for watching and commenting!
Love this channel, it's like a no fluff version of Mythbusters that just gets to the point and gives you the answer. I can and will watch these all day.
That is high praise! Thank you 👍
What is the worst or, silliest portrayal of defibrillation in a movie?
The Thing! Pretty SHOCKING! 😏
MR BEAN - One of my favourite skits as a kid 😂 czcams.com/video/_bseE0Od_zM/video.html
ALL of them! I can't contain myself when I see it. I will always cry out, "You can't shock asystole!!" Even in movie theaters, only a little quieter. 😂
@@learnmoreabout of course, Mr. Bean gets a pass. 😆
Not exactly what your asking but this is the greatest explanation of the heart and a defibrillator ever given ❤
Heart is bad, all it knows is violence 😂
czcams.com/video/IfWm4COyV0o/video.htmlsi=KRryhAJizyEg39MD
Thanks for sharing. It is a hit and miss thing. I must say. In my country, South Wales. We have these everywhere. It helps to know what caused the heart to stop in the first place...but 25% chance? that's wild.
8:22 that is the most important learning from me
Also AED = automated external defibrillator
Okay, the character's frowning face at the end is hilarious 🤣🤣
Luckily AEDs monitor the heart beat and decide themselves when to shock, not the user. So wrong usage is almost impossible.
Which movie / TV show has your favorite example of defibrillation, most realistic or ridiculous?
The original Mr Bean series 😂 Comedy gold as a kid! I'll have to watch that again...
Homer in the hospital getting a paddle shock, then raising his hand like ‘keep’em coming!’ and Dr Hibbert shocking him several times more.
The pilot episode of Helluva Boss also had three people (6 paddles total) applied all over a kid’s body and when he breathes in the doctor says “Holy shit that actually worked!”
BBC casualty which I think is this clip 5:30 came from but before they use a defibrillator a member of staff says they go into VF which is the medical aberration of Ventricular fibrillation hence why they are called Defibrillator, I already know that because I have done a Frist aid course but I did have to googled the correct spelling.
@@bendordoy4815 I think the clip you’re referring to is a clip we used from the BBC Series - Helicopter Heroes. Well done on completing your First Aid Course 💪 And thanks for your comment 👍
@@DebunkedOfficial thank it was quite a few years ago so my Frist aid certificate has expired now but I can remember a lot of what I learned, oh so it was a real life incident not a fictional one.
Thank you for debunking the use of defibrillator in movies,now I'm gonna flex this information in front others:)
The last animation scene was hilarious!
thank you for real and true information
Great video
8:22 The guy reminds me of scenes from the Sherlock Holmes movies when Watson was thumping on Holmes' chest
Please excuse my confusion. Just a writer doing research. I may have missed something but, does this mean when we see people drown in a movie and they are brought back by CPR, that it is also inaccurate? So CPR is only good when the person's heart is still beating? What's the process to resuscitate them? Is the DEFIB used when people are "coding" like is always mentioned? I'm really enjoying your videos. They provide a wealth of research information! I'd appreciate the infomration.
Absolutely love the concept of this channel, and I really want to love it... But unfortunately, the loud over the top voice you put on really takes from the enjoyment. I genuinely think you would get more followers if you just toned it down a bit. Otherwise though, brilliant content and really appreciate the amount of work and research gone into it.
This is one of the reasons I love the Stargate TV shows. I can’t think of any time they did defibrillators wrong; this may have been because they all had a USAF advisor on set who would have told them not to do that.
Thanks debunked I love your content🤟
Thanks for watching and commenting 👍
If someone flatlines, don’t they use adrenaline shots to “kick-start” the heart?
That's wild
Adrenaline and chest compressions are all someone can do, I believe. Even then it’s a huge gamble. I could be wrong though.
Also a small.note when you diffibrilate someone aka shock him, most of the time the patient is unconscious. So after delivering the shock it's merely impossible for him to wake up eyes open (global miscinsception in hollywood science). Most of the time, to.evaluate the success of this procedure is to have a normal rythm on the monitor and check for central pulse (carotid"neck" or femoal"thigh") if one of the is missing, resume CPR for 2mn and start again.
No one thought the paddles are rubbed together to charge the machine.
like your tone man
Thanks! 😁
This happened to me. Died from a cardiac arrest. Yep, getting a shock works.
8:21 “bro get up”
I never seen a defi in use, I hope it stays that way^^
As a cardiovascular ultrasound tech, absolutely, 100%. Seen too many real-world examples for anyone to claim otherwise
How do they start hearts from heart transplants then?
0:42 or the films
Problem is theyre not blasting "Kickstart My Heart" when they blast a flatlined patient
Are there any known methods to actually restart the heart that stopped beating? And if yes, would it be possible to perform it by a random person a street?
And one more question! How to know, when to use defibrillator when we find someone unconscious on the street?
Take a first aid course at the Red Cross, they are free. The defibrillator, after being hooked up, will messure and estimate if a shock is usefull. The device will give you spoken instructions after you open it.
Yes, you use CPR. And AED recognise itself, you just apply pads and follow the voice instructions. Serch AED demostration video.
And the AED will not zap unless you push the button to zap
Late to the party here, but the only thing you can do is CPR if it's asystole, to keep the brain supplied with oxygen long enough for medical professionals to get to the patient. AED actually have an automatic indicator whether the rhythm is shockable, if it's flat, it won't let you shock. Only drugs can deal with asystole.
What about chest compressions?
Can they restart a stopped heart?
I should know this I've done a first aid course... But it was a couple of years ago now...
Yes and no. It _can_ happen and sometimes does, but rarely. Really you're doing chest compressions to keep blood moving to the brain and other organs until paramedics can get there to give medicine that can restart the heart. Or get the person to the hospital for a procedure.
So what do you do to start a heart that is flatlined? Give the corpse a kick like it's an old TV and see if that doesn't pop it back on?
In movies, if the heart stopped beating completely, they often inject Adrenalin. Is this also a myth or can Adrenalin in combination with CPR really restart the heart?
What about heart transplant? I mean, it should not beat at all, yet they still somehow jumpstart it using defibrillator after transplanting it to another person
They have a machine hooked up to keep your blood circulating, then the new heart gets connected, and it should beat after its attached to the arteries.
I have atrial fibrillation and supra ventricular tachycardia and in the last 14 years I have had the defibrillator used twice on me. I am 38 years old, we are looking into the implant here in Australia.
It is really bad the way they show it on the movies.
so how would you start a heart?
Interesting
Why is this a topic even on “debunked?” I do this for a living as an ER doctor and can assure you that in the right circumstances when indicated (I’m not going to go through when and why it’s indicated), it definitely works and saves lives. This has been around for decades and decades… why is this something that needs debunking? Hell, the average person doesn’t even need to know when or why a patient could or should be defibrillated or not. It’s not something any regular person would even do or have access to unless you’re an emt or work in a hospital.
I’m heartbroken! 😭
my father died, thought he wasn't dead, which then caused him to not be dead
It's stops your heart, irregular rhythms, in the hope your heart restarts in the correct sequence.
Ight we got medical theory and film theory
Honestly its almost dangerous for Hollywood to do that.
The end of t last video was just
Or you could just grab onto something
Doctors and the orderlines clap this.
Can't recharge a dead battery.
Dr. Strange is not conscious in the scene, it's his spirit communicating with her above his body!
But don’t heart transplants always involve using paddles to trigger the first beating of the new heart?
Why is the animation style always changing? Is there an unspoken of civil war in the debunked HQ
Why is this channel kinda dying it's still good lol
How come this video is unlisted?
Thanks for askinb, sadly it's been age restricted for some reason. We'll re-release soon hopefully once it's been sorted out.
@@DebunkedOfficial I see, thank you, that's ridiculous...
@@jurio3117 We're all a bit confused tbh.
SO WHEN THEY TRANSPORT A HEART TO TRANSPLANT, IS IT STILL BEATING BY ITSELF?
I would subscribe to this channel but the subscribe button is greyed out.
Thanks! Try this subscribe link and let me know if works or not 👍 www.youtube.com/@DebunkedOfficial?sub_confirmation=1
Yo I’m a nurse and I’m the hospital we’re more often than not will use the sticky pads not the paddles. We have paddles but I’ve never seen them used
Any emt will tell you that you don't shock a dead heart. The new and is great I got to see it used a few days ago. I won't lie I wish I hadn't witnessed it because it broke my heart to see someone that bad off, but if that wasn't used he would have definitely died
The worst defibulator scene ive seen is prob in el camino. They werent even using the defibulator, and there wasent even a defibulator to begin with. They were just shooting each other with guns.
I didn't know they re-made Flatliners. Wow, Hollywood is completely out of new ideas. No wonder there are so many comic book movies. That AI stuff is only going to make it worse. Lame..
No… 😔 If it’s contracting irregularly (Ventricular fibrillation) then a shock will potentially revert it to normal. That is why the device is called a ‘defibrillator’
A non contracting heart 🤷♂️ Call the undertaker.
So is there no way to bring a person "back to life"? I think ive heard or read some stories of people that were dead for a few seconds or minutes but are well now
If they are flatlined, only CPR and drugs can bring them back
@@TimRockIt If you're flatlined, defibrillation can't bring you back on its own like it's shown in the movies and TV. It's not standard procedure to defibrillate a flatlined patient, although it can't hurt since it can't get any worse. Defibrillators are used to correct irregular heartbeats (fibrillation, hence the name), so it's certainly possible that you got zapped after CPR and injections restarted your heart, but it was beating irregularly. Also don't forget to thank the medical professionals God sent you, they deserve praise too
IT’S IN THE NAME - DE-FRIBULATOR
04:41 That guy is really going for it! 🤣
Not sure he has a clue what he’s doing 😂
The guy at 04:41 doesn't have a clue! 🤣
He really doesn’t 😂 I burst out laughing when I found that particular stock footage gem!
If we were to make a grave yard of how many poor animates people have died in all of these videos how many would there be
We certainly get a dose or two from Flatliners...
Both iterations!
So Pulp Fiction adrenaline injection was genuine
It doesn't work like that...
Nope!
Which is from a medical perspective "not ideal" 😂
😆
Glad you liked that 👍
FIRST YAY
I'm glad this video didn't.....flat line....
I love it!
Bruh
Can you CPR a chest till the brain ..functions again for a short while?
Maybe........if the soul of the body is allowed back.
Hollywood science 🤣
