The time from the beginning of the P wave, indicating atrial depolarization, to the beginning of the QRS complex, representing ventricular depolarization, is the PR interval. This represents the ...

[29] In another study, a prolonged P wave interval of >120 ms was associated with higher risk of stroke; [40] atrial late potentials (using signal-averaged ECG) were the strongest predictor ...

P-wave duration was measured from the conclusion of the TP segment (P-wave onset) to return to baseline (PR interval). For biphasic P waves, both positive and negative deflections from baseline ...

The waves on an ECG include the P wave, Q wave, R wave, S wave, T wave and U wave. Interval: The time between two specific ECG events. The intervals commonly measured on an ECG include the PR ...
