Key Learning Points
ECG Waves P, Q, R, S, T
P Wave Page 2
- The P wave(a) represents right(b) and left(c) atrial depolarization.
- Since the right and left atriums depolarize almost simultaneously their waves are superimposed into one wave on the monitor.

P Mitrale Page 3
- P Mitrale is an "M" shaped P wave(a) produced from an enlarged left atrium(b).
