Junctional rhythm is not the same as a sinus rhythm. 2017 Nov. 60(11):344-52. This is because the place where pacing takes place (the drum section) moves to another area known as the atrioventricular junction. History. 286-95. Braunwald E, ed. 65(1):1-8. New York, NY: WB Saunders; 2001. Kim D, Shinohara T, Joung B, et al. Clinical Cardiac Electrophysiology. For instance, AV dissociation with complete heart block, defined as an atrial rate that is faster than the junctional escape rate, is more likely to cause symptoms than AV dissociation with a sinus rate slower than the competing junctional pacemaker.
