Abstract
This report describes the necessity of knowledge concerning electrocardiogram for physical therapist, and also deals with some principal points for studying it. By using electrocardiogram which indicates electrical activity of heart, we can obtain the volume and direction of its electric potential multilaterally, and can predict its electric axis. It is important that we should always consider in which part of heart an irregular wave occurs with knowledge on mechanism and stimulus-conduction system of heart when recording electrocardiogram of our patients.
