Failed Biventricular Pacemaker
Report:Sinus rhythm 63/min 1 Left atrial abnormality (LAA) 1 P wave 0.16” First degree AV block 3 PR 0.28” Right axis deviation +250o Left bundle branch block 3 Dual pacemaker, failed, 70/min 2 Comment:The combination of LBBB and RAD is virtually
Pacemaker Rhythm and LBBB
Report: Electronic demand pacemaker rhythm 70/min 2 Atrial fibrillation 2 Left bundle branch block (last 3 beats) 6 Comment: If it were not for the rhythm strip, few would notice the transition from pacemaker to supraventricular rhythm at the end of th
Fixed-Rate Pacemaker
Report: Sinus rhythm 1 Left bundle branch block 3 Fixed-rate (asynchronous) ventricular pacemaker 39/min 6 Comment: Large spikes denote a unipolar pacemaker, a feature not seen in temporary pacemakers. The slow rate would normally imply the battery de
Atrial Pacemaker: Failure to Sense
Report:Sinus rhythm 80/min 1 Atrial pacemaker 2 Failure to sense 2 Blocked atrial P waves of pacemaker origin 4 Left bundle branch block 1 Comment:There is a profusion of pacemaker spikes and LBBB complexes, giving an initial impression of variable a
Atrial Sensing and Pacing
Report:Sinus rhythm 75/min 1 VEB 1 Atrial-sensing ventricular pacemaker 3 Atrial sensing and pacing ventricular pacemaker (last beat) 4 Left atrial abnormality (LAA) 1 Comment:This is a DDD pacemaker, responding to both the atrial activity and the la
Pacemaker or LBBB?
Report:Sinus rhythm 65/min 2 Atrial-sensing ventricular pacemaker 8 Comment:This seems unimpeachable, except for lead V1 having the morphology of LBBB (steep descent, slow ascent) instead of expected right ventricular paced or ectopic beat (slow descent
Acute Infarction with Pre-existing LBBB
Report:Sinus rhythm 60/min Left atrial abnormality (LAA) Left bundle branch block Acute inferior & anterior infarction Comment:The diagnosis was based on new and marked ST segment elevation in the inferior leads and V3 as well as concordant T inversio
Anterior Infarction and Rate-Dependent LBBB
Report:Sinus rhythm 66/min SVEBs, blocked Rate-dependent left bundle branch block Anterior infarction ?age Comment:The pauses created by the non-conducted SVEBs are long, but still not fully compensatory. The complexes terminating the pauses are norma
LBBB: Primary T Wave Changes
Report:Sinus rhythm 65/min First degree AV block PR 0.28â Left bundle branch block Primary T wave changes 2, 3 and aVF Comment:LBBB always causes repolarisation changes directed opposite the main QRS deflection, especially its terminal half. They a
Inferolateral Infarction & LBBB
Report:Sinus rhythm 88/min Left bundle branch block Acute inferolateral infarction Comment:Unlike the previous caseâs IVCD, this one shows typical LBBB, with sharp S descent and slower ascent in V1. Despite this, there is a concordant ST segment elev
