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. Web1 de nov. de 2024 · Normal PR Interval. A normal PR interval is 0.12 to 0.2 seconds. This corresponds with four to five ECG printout squres. Any result of or between 120 to 200 milliseconds is considered normal. This shows that electrical activity is running smoothly from the sinoatrial node to the ventricles.
