Alternating Paced and Fusion Beats
Report: Slow atrial or junctional rhythm 38/min 2 Ventricular pacemaker rhythm 79/min 2 Superior electrode placement 2 Fusion in alternate beats 2 Presumptive RBBB 1 ST/T changes of uncertain significance 1 Comment: The narrower (0.12 sec) complexes are p
Atrial Pacemaker Captures During 2:1 AV Block
Report: Sinus rhythm 0.5 AV sequential (known DDD) pacemaker 0.5 Atrial sensing & pacing 1.0”escape interval 1 AV interval 0.30” atrial-paced beats and one conducted sinus beat 1 Failed ventricular pacing 1 Second degree AV block 2:1 alternate paced
DDD Pacemaker: Fractured Ventricular Lead
Report:Dual AV pacing 99/min 1 No ventricular capture, atrial 100% pacing 7 Right bundle branch block 2 Comment:The patient arrived to Casualty in sinus rhythm with sinus pauses and both escape and premature SVEBs (Fig 114a). He still had the SSS. The
Lean Child of Fat Parents
Report:Sinus rhythm 60/min 1 First degree AV block 1 Right bundle branch block 1 AV sequential pacemaker rhythm 60/min 1 No atrial capture 1 Ventricular pacemaker rhythm 60/min 1 Superior electrode displacement 1 Fusion beats 3 Comment:The tempor
RBBB: Paced Fusion Rhythm
Report:Sinus tachycardia 107/min 1 Atrial-sensing ventricular pacemaker, 100% capture 2 Presumptive right bundle branch block 5 Fusion complexes throughout 2 Comment:This is similar to the delectable deduction in Case 38, except that the pacemaker’s
Escape-Capture Bigeminy in AF
Report: Atrial fibrillation 1 High-grade or complete AV block 1 Junctional rhythm 2 Pacemaker rhythm 1 Escape-capture bigeminy 1 Left anterior hemiblock (LAHB) 1 Right bundle branch block 1 Anteroseptal infarction, age uncertain 1 ST/T changes con
Pacemaker Completing the RBBB
Report:Sinus rhythm 70/min 1 Atrial pacemaker rhythm 55/min 2 Failure to sense 3 Capture beats 2 Right axis deviation +95o 1 Right bundle branch block 1 Comment:The atrial pacemaker discharges with complete regularity at 55/min, obviously heedless o
Delectable Deductive Diagnosis of RBBB/LPHB
Report: Dual chamber pacemaker rhythm 70/min 2 Frontal plane axis –20o 2 Ventricular fusion complexes throughout 3 Probable underlying right bundle branch block with right axis deviation 3 Comment: I make no apologies for the subcontinental flavour of
Failure to Sense
Report:Atrial fibrillation 1 Ventricular pacemaker 1 Failure to sense 2 R-on-T pacing 2 Fusion beat 2 Incomplete right bundle branch block 1 Nonspecific ST/t changes 1 Comment:Failure to sense is only intermittent, since the pacemaker discharge is
Junctional Extrasystoles with RBBB Conduction
Report:Sinus rhythm 81/min 1 Atrial-sensing ventricular pacemaker 3 AV interval 0.10 sec 1 Junctional premature beats with RBBB conduction 4 ST/T changes consistent with ischæmia 1 Comment:Like in the previous case, there are large ventricle-pacing s
