Normal pr wave
WebPocket Guide - ECG & ECHO WebThe normal PR interval (measured from the beginning of the P wave to the beginning of the QRS complex) is 0.12 to 0.2 sec. A uniformly prolonged PR interval is referred to as first-degree AV block or preferably, as PR prolongation (see Chapter 17 ). A short PR interval with sinus rhythm and with a wide QRS complex and a delta wave is seen in ...
