We present the case of a 72-year-old male who underwent a permanent transvenous DDD pacemaker implantation for symptomatic complete heart block. The postoperative surface electrocardiogram (ECG) revealed a right bundle branch block (RBBB) pacing pattern with transition in lead V3 and left bundle branch block (LBBB) in D1, suggesting a malpositioned ventricular lead in the left heart. Malpositio...
An unusual patient is described in whom electrophysiological studies strongly suggest the occurrence of Mahaim conduction. The patient whose electrocardiogram previously showed a left anterior hemiblock pattern then developed advanced atrioventricular (AV) block (AH block). Beats conducted through the atrioventricular node always had a short HV interval (20 ms) and QRS complexes of left anterio...
