WebPR intervals of less than 0.12 s were found in 3.8%, and 2.7% had intervals of more than 0.22 s. Short PR intervals of the Lown-Ganong-Levine type are not uncommon in old age. Lengthening of the PR interval in the normal range appears to be related to acquired and disease factors and is not due to a gradual ageing process. In electrocardiography, the PR interval is the period, measured in milliseconds, that extends from the beginning of the P wave (the onset of atrial depolarization) until the beginning of the QRS complex (the onset of ventricular depolarization); it is normally between 120 and 200 ms in duration. The PR interval is sometimes termed the PQ interval.
