Popis: 1. 1. The duration of atrial electrical activity, the P-P interval, and the atrial rate are measured in seventy-four electrocardiograms of thirty-six patients with atrioventricular block. 2. 2. The range of the duration of atrial electrical activity (P + TP) is 0.19 second at an atrial rate of 300, to 0.53 second at an atrial rate of 62. 3. 3. A linear relationship exists between the duration of atrial electrical activity and the P-P interval with the duration of atrial electrical activity increasing with increasing P-P interval. Decrease in the duration of atrial electrical activity occurs with increase in atrial rate.
