WebOnce you've determined that a P wave precedes each QRS complex, you must scrutinize the P wave for contour and size. The normal P wave is less than 0.12 seconds in duration, and the largest deflection, whether positive or negative, should not exceed 2.5 mm. An abnormal P wave may indicate atrial enlargement. WebJul 7, 2024 · The P wave in an ECG complex indicates atrial depolarization. The QRS is responsible for ventricular depolarization and the T wave is ventricular repolarization. What happens during repolarization of ventricles? As the ventricles repolarize, there is another change in voltage across the cell membrane as the cells become more negative again. fly web bulbsWebFeb 2, 2024 · There are numerous types of pacemaker, including atrial pacemakers that pace only the atria, ventricular pacemakers that pace only the ventricles, and pacemakers that pace both the atria and the ventricles.

WebThe P Wave: The P wave of an electrocardiogram (EKG or ECG) represents the depolarization (i.e., contraction) of the atrial muscles. The atria are the top two chambers of the heart. When these muscles contract, the atria pump blood into the bottom two chambers of the heart which are the ventricles.
