Figure 1 illustrates the composition of a single channel ECG segment. A normal ECG beat consists of a P wave, a QRS complex, an S wave, and a T wave in sequence. The P wave represents depolarization of the atria (i.e., top chambers of a heart); the QRS complex represents …

Sinus rhythm (which is the normal rhythm) has the following characteristics: (1) heart rate 50–100 beats per minute; (2) P-wave precedes every QRS … WebAn electrocardiogram (EKG) is a test that records the electrical impulses of the heart. It assesses heart rhythm, chamber size, and muscle thickness. Our arrhythmia team uses EKGs to evaluate problems including: Arrhythmias: Heartbeats that are too fast, too slow, or erratic. Congenital heart disease: Birth defects in the heart.
