Question

In ECG, P-R interval corresponds to?

Answer 1

In ECG , the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrialdepolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200ms in duration. The PR interval is sometimes termed the PQ interval .
