P Wave - an overview ScienceDirect Topics

WebThe other main components of an ECG are: P wave – It represents the depolarization of atria and represents atrial contraction. It precedes the QRS complex T wave – It represents the repolarization of ventricles and the end of the systole. It follows the QRS complex. Webof the P-wave, if present, to the QRS-complex. If there is a P wave before each QRS and the P is in the same direction as the QRS, the rhythm can be said to be sinus. For instance note in the EKG segment below that there is a P-wave before each QRS (highlighted in blue) and that it is pointing up as is the QRS segment. images of mandalas to printWebDec 7, 2024 · An electrocardiogram — abbreviated as EKG or ECG — measures the electrical activity of the heartbeat.
