WebThis electrical activity generated by the heart can be measured by an array of electrodes placed on the body surface. The recorded tracing is called an electrocardiogram (ECG, or EKG). A "typical" ECG tracing is shown to the right. The different waves that comprise the ECG represent the sequence of depolarization and repolarization of the atria ...
WebThey seldom, however, are considered normal when the T wave amplitude is less than 10 percent of the R wave amplitude. In the posterior leads (V 7 –V 9), the T wave is upright. 35.
