WebOct 29, 2024 · P waves are generated by organized activation of both atria during sinus rhythm, whereas fibrillatory waves are caused by disorganized and chaotic atrial electric activity during AF. Thus, the simultaneous recording of the P waves during AF on the baseline ECG was a contradictory finding. WebThe P-wave is generated by depolarization (activation, contraction) of the atria. The PR interval is the interval between the start of the P-wave and the start of the QRS complex. The PR interval determines whether impulse transmission from atria to ventricles is normal.

WebDec 2, 2024 · The electrocardiograph provides vital information about the rate and rhythm of the heart and the conditions of the heart muscles. Each cardiac cycle (or in very common terms we may say each heartbeat) produces a P wave, a QRS complex and a T wave. The QRS complex has three separate Q, R and S waves. P-Wave: WebThe QRS complex may be R alone, QS (no R), QR (no S), RS (no Q), or RSR ′, depending on the ECG lead, vector, and presence of heart disorders. Normally, the QRS interval is 0.07 to 0.10 second. An interval of 0.10 to 0.11 second is considered incomplete bundle branch block or a nonspecific intraventricular conduction delay, depending on QRS ...
