arrhythmic ECG / EKG with auscultation heartbeat sound

READ THIS FIRST! first of all, sorry about the bad video quality, but i had to record it with my (cheap) webcam in order to be able to sync in with the microphone recording. this is a video of my ECG with auscultation sound in real-time, where i do various things to trigger arrhythmia / alter the ECG reading. most of that is explained in the video itself. i labeled the arrhythmia when it first appeared: VES means ventricular extrasystole, which is equal to PVC (premature ventricular contraction). SES means superventricular extrasystole. LVOT means left ventricular outflow tract. APEX means tip of the heart. i am using a Hellige SMU intensive care monitor and a Logitech USB microphone.
