Measuring Capture and Sensing Treshold on PACE Model 203

How are the capture and sensing thresholds measured and the sensitivity and stimulation amplitudes set accordingly on the external pacemaker PACE model 203?
PACE Model 203 offers several possibilities to determine the sensing threshold and to adjust the sensitivity of the pacemaker!
In this context, the pause function for recording the intrinsic cardiac activity and the automatic readjustment of the sensitivity, the AutoSense function, are presented.
PACE Model 300 also offers all of the functions presented.
CoraSim, the interactive heart simulator, enables safe training without a patient.
