The time from the beginning of the P wave, indicating atrial depolarization, to the beginning of the QRS complex, representing ventricular depolarization, is the PR interval. This represents the ...
Prolongation of the PR interval by more than 200 ms, which signifies first-degree atrioventricular block, has been found to increase the risk of developing atrial fibrillation, the need for a ...
The PR interval is the time from the beginning of the P wave (atrial depolarization) to the beginning of the QRS complex (ventricular depolarization). The normal PR interval measures 0.12-0.20 ...
