This video on cardiovascular system physiology describes the various waves, intervals and segments in ECG (electrocardiogram). It also describes how to read an ECG

1. Waves of ECG: The amplitude and duration of waves of ECG i.e P, QRS and T waves
2. Segments of ECG: PR segment, ST segment, TP segment, difference between Pr segment and interval, significance of TP segment

PR segment starts from the end of P wave and is to the beginning of QRS complex.

3. Intervals in ECG: PR interval, ST interval, QT interval, RR interval, PP interval
4. How to look for sinus rhythm in ECG?
Look whether each P wave wave is followed by WRS complex or not. If yes, it is sounds rhythm
5. How to calculate heart rate from ECG?

Count the number of small squares of ECG paper between R-R interval peak..

To calculate heart rate divide 1500 by the number of small squares 

How to determine duration in ECG paper?
