PR interval represents the time from the start of the atrial activity to the start of ventricular activity
Explanation:
An electrocardiogram is an electrical action produced by the heart that can be estimated by an arrangement of electrodes located on the heart exterior. The P wave is the initial wave on the ECG because the performance potential for the heart is created in the sinoatrial (SA) node, positioned on the atria.
The QRS collection points to the sequence of the Q, R, and S waves. The R wave, a skyward wave, is the usual obvious characteristic of an ECG. The duration of time from the incipience of the P wave to the start of the QRS system is termed the PR interval. This interlude depicts the time among the origin of atrial depolarization and the incipience of ventricular depolarization.
