Abstract

We present a case of paroxysmal atrioventricular block with atrial pacemaker shift, focusing on the change of P-wave morphology.

Keywords: P‐wave morphology; atrial pacemaker shift; paroxysmal atrioventricular block; ventricular arrest.

(A) Complete atrioventricular block (AVB) with a junctional escape rhythm of 40 bpm with P‐P intervals between 720 and 780 msec. Sharp P‐waves in leads II, III, and aVF were observed. (B) During 1:1 AV conduction (a presumed sinus rhythm), the P‐P intervals were between 960 and 1000 msec with dull P‐waves in leads II, III, and aVF
