WebThe PR interval normal range is 0.12-0.2 seconds, the QRS complex range is 0.06-0.10 seconds (greater than 0.12 is considered abnormal and you would need to consider a bundle branch block), the QT interval is approximately 40% of the heart rate. The P wave of an ECG indicates atrial contraction. The P wave on an ECG represents atrial contraction. WebNormal sinus rhythm. The P waves in leads I and II must be upright (positive) if the rhythm is coming from the sinus node. Conduction. Normal Sino-atrial (SA), Atrio-ventricular …

The majority of authors accept it as Normal …
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 ). WebThe key to interpreting this rhythm lies with beat 4, which clearly occurs earlier than expected, and which is preceded by a seemingly normal PR interval. This strongly suggests beat 4 is sinus-conducted. Note the appearance of beat 4 in simultaneously recorded leads V1, V2, and V3.
