Webb1 dec. 2015 · The P wave is generated by atrial depolarization. Because the muscle mass of the atrium is small, the P wave is a relatively small signal. The QRS complex represents ventricular depolarization and is the dominant signal of the electrocardiogram because the ventricular mass is large. WebbThe P-wave, PR interval and PR segment. ECG interpretation traditionally starts with an assessment of the P-wave. The P-wave reflects atrial depolarization (activation). The PR interval is the distance between the onset of the P-wave to the onset of the QRS complex. The PR interval is assessed in order to determine whether impulse conduction from the …

Webb29 dec. 2024 · The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body. It starts at the beginning of one heartbeat and ends at the beginning of another. The process begins as early as the 4th gestational week when the heart first begins contracting.
