ECG (Electrocardiogram) EKG Lesson
Vložit
- čas přidán 29. 07. 2024
- Electrocardiogram An ECG may be recorded by detecting and amplifying the electrical activity generated by the myocardium, as detected on the surface of the body. In order for muscle to contract it must depolarize. After contraction the muscle will repolarize, prior to the next depolarization. P waves are generated by atrial depolarization and so represent atrial contraction, QRS complexes are generated by ventricular myocardial depolarization so represent ventricular contraction. T waves are generated by ventricular myocardial repolarization and so do not represent active muscular contraction. As each QRS complex represents ventricular contraction, each is associated with one arterial pulsation. A three lead ECG is commonly used to monitor the heart rhythm. However, if a 12 lead ECG is used the heart may be 'viewed' from 12 different positions. This allows any pathology in the myocardium to be localised.
It's 2022 and I still find myself returning to your videos and watching them because I truly feel like you're one of the best! I want to thank you for teaching me the cardiovascular system two years ago! I attended lectures at uni, read textbooks and watched multiple CZcams videos but no one explained the cardiovascular system the way that you did. I am so grateful to have come across your videos when I did. Thank God! THANK YOU THANK YOU THANK YOU! God bless.
You have done in minutes what my teacher failed to do in 2 years. Absolute legend.
You bring tears to my eyes! you are the epitome of a professor who knows how to make a difference in their student's lives. Thank you for giving me the confidence to face A&P.
The tempo of speech, pauses, repetitions, accents - all those make you an amazing lecturer. None Of my professors in nursing school taught us this way . They were using PowerPoint presentations that were accompanying our textbook , unlike Dr Campbell who draws everything from scratch himself
I am a Professional Nurse and Dr. John Campbell is always with me as a guide. Every time I forgot something I'll just turn on my laptop and watch his videos. Really Dr. Campbell helps me a lot in my profession. THANK YOU VERY MUCH DR. JOHN CAMPBELL because of you I was able to carry out my profession effectively and safely because of your teachings.
Thats great Friendo, thanks for letting me know, do click lots of like buttons, this helps the channel.
Dr. John Campbell yes Doc sure I will. I even endorse your channel to my colleagues, friends and family to help them too . Thanks a lot.
Can I just express my gratitude over your command of subject and eloquence and ease; how you clear concepts of medicine, without exhausting the neurons. Meanwhile keeping the vigor to learn with your remarkable wits. lots of Respect from Pakistan. 15/1/2022.
Dr.Cambell u r really agreat teacher that I have seen ever
This was one of the most informative videos I've watched. Not only could I follow your clear explanations but it was also very inspiring! I'm excited to learn more about cardiovascular health and EKG readings. Fantastic. Please keep the videos coming.
That last question you answered really blew my mind ! I always asked myself why would an infarcted area look elevated. Thanks a lot for the explanation, it really helped me understand it ! Great job, this video clarified a lot for me! And I wanna thank that girl for asking you that question too !
You are the best!
Sending love all the way from Africa, Zambia ❤
Thank Dr john
Currently taking EKG and I'm confused by my instructor. Thank God for your videos! God bless you.
These black belt level teachers are so important. I’m so glad CZcams is around today and we can all learn from them.
u r a legend....I wish I had teachers like you....
I love your lectures! I am so grateful that you have taken the time and trouble to post them, so THANK YOU!
You are a charismatic, knowledgeable speaker... in so many ways. I love all your side notes- like the vagus nerve thing... love it!
I am a 1st year nursing student and I wish I was in your class.
Hello Salinda, Thanks for your encouraging comments, how is your training going, are you a second year now? John
Dr. John Campbell Yes I am in second year. Struggling with the poor lectures here. Could you possibly post anything on conditions effecting the kidney and diseases of the GI tract like PUD and Duodenal Ulcers?
U most be a nurse by now
Amazing teacher... Wish I had more like him when I was in college!
GOAT...Greatest of All Time. Dr. Campbell is just a genius. Wish i could train under you. Your understanding of basic priniciples and teaching style inspire me so much. Make my wish come true.
Thank you so so much Dr.Campbell.I am a 5th year Medical Student and ECG was never as easy and understandable as you explained.I will be keep checking your channel regularly in the future.Your knowledge is giving me more and more inspiration.Thanks a lot!
Thankyou for these excellent video’s. Sharing a personal exp. This was probably 25 30 years ago. My dad an engineer trained abroad primarily the UK and Europe and installed many medical electronic instruments in India. He would visit hospitals and train pathologists, doctors on the newly imported machines. I remember him referring to the PQRST wave patterns, ECG etc. As a kid, I could never understand back then. Now it’s all so interesting and clear.
i just noticed i watched a 38 minute video and i was totally engrossed by what the Dr was teaching and i drive a fork truck for a living lol
There is no harm in learning. Saying that, I drive semi for living... 👍
I found your page at the end of the last semester when i was taking A&P 1 now i am taking A&P 2. I graduate in publishing in my country and wanted to make a big change in my life by majoring in sonography. Tkx to your video i got confidence because french is my first language and you make it so easy for us to understand. Thank you Sir. You are a great teacher.
