Webb25 okt. 2024 · 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 seconds (120-200 milliseconds). A prolonged or shortened PR interval can indicate certain disease. Webb1 jan. 2001 · Conclusions Slow pathway modification in patients with atrioventricular nodal reentrant tachycardia and a prolonged PR interval is highly effective. However, there is a significant risk of development of delayed atrioventricular block, particularly when the procedure results in total elimination of the slow pathway.
