WebApr 27, 2014 · A junctional rhythm occurs when the AV node takes over as the primary pacemaker because either the SA node failed or the AV node blocked the atrial impulse. The AV node only generates an electrical impulse at a rate of 40-60 bpm, so you typically see a much slower heart rate. There are some circumstances, however, where the AV node … WebJul 18, 2024 · Junctional Escape Rhythm.

WebAug 19, 2024 · Typically, electrical impulses produced by the “pacemaker” cells of the heart located in the sinus node control the heart rhythm. But in automatic SVT, cells in some other location within the atria (upper chamber of the heart) begin producing their own electrical impulses. These impulses are more rapid than the impulse in the sinus node, and thus …

WebJunctional rhythm is a regular narrow QRS complex rhythm unless bundle branch block (BBB) is present. P waves may be absent, or retrograde P waves (inverted in leads II, III, and aVF) either precede the QRS with a PR of less than 0.12 seconds or follow the QRS complex. The junctional rate is usually 40 to 60 bpm.
