From: Marked First Degree Atrioventricular Block: an extremely prolonged PR interval associated with Atrioventricular Dissociation in a young Nigerian man with Pseudo-Pacemaker Syndrome: a case report

Figure 3

Marked First Degree Atrioventricular Block with extremely prolonged PR interval (A) transiting into Mobitz type II(B), Mobitz type I(C), Atrioventricular Dissociation (D) and return to First Degree Atrioventricular Block (E) sequentially in fourth long rhythm strip (4). Similar events occurred in the fifth long rhythm strip (5) but the sixth long rhythm strip (6) maintained First Degree Atrioventriccular Block throughout the length of the strip. Varying RR intervals occurred because of the presence of variable degrees of Atrioventricular Block.
