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
Pseudo-Wenckebach due to Low Upper Rate Limit
Report: Sinus rhythm 92-96/min 0.5 Conducted sinus capture beat (penultimate QRS) 0.5 First degree AV block (PR 0.24”) 0.5 Second degree AV block (last cycle) with ventricular pacemaker escape beat 0.5 Atrial-sensing ventricular pacemaker 1 4:3 pseu
No Pacing and 2:1 Failure to Sense
Report:Sinus rhythm 55/min 1 Demand pacemaker: failure to pace 2 2:1 failure to sense 5 LVH voltage (SV2 25mm) 0.5 Left atrial abnormality (LAA) 0.5 Old inferior infarct 0.5 Possible old anterior infarct (loss of R height from V2 to V3) 0.5 Commen
Pacemaker Blues
Report: [Code Blue] Pacemaker rhythm 72/min 1 QRS 0.36” 2 Pacemaker rhythm 72/min 1 QRS 0.20” 2 AV dissociation 2 Accelerated idioventricular rhythm 78-84/min 2 Comment: The QRS complex width - in paced beats, bundle branch blocks, or VEBs - gener
Carotid Sinus Massage & Atrial Pacemaker
Report:Sinus rhythm 53/min 1 Atrial pacemaker rhythm 41 - 42/min 2 Second degree AV block 3 Single non-conducted paced beat 4 Comment:Carotid sinus massage may induce AV block regardless of the nature of atrial activation. The patient's response is no
Atrial Pacemaker: Intermittent Failure to Sense
Report: Adler Roy 18/4/99 11065929Sinus rhythm 66/min 1 Atrial pacemaker discharge 53/min Intermittent failure to sense 2 Pacemaker capture beats 2 Phasic aberrant RBBB conduction 2 Left atrial abnormality (LAA) 1 Anterior infarction, indeterminate
Controlling the Ventricular Rate: Upper Rate Limit
Report: Atrial fibrillation 5 Paced ventricular response 115 – 119/min 5 Comment:The unit is pacing quite close to its upper rate limit of 120/min, obviously in response to atrial fibrillation (hence no atrial pacemaker activity – it remains suppressed
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
VEB and DDD Pacemaker
Report:Sinus rhythm 73/min 1 VEB 3 Atrial-sensing ventricular pacemaker 4 Atrial-paced beat 2 Comment:Universal (DDD) pacemakers can both sense and pace the atria. The pause created by the VEB is terminated by an atrial-paced P wave and ventricular-pa
Sensing and not Sensing Atrial Fibrillation
Report:AV sequential pacemaker rhythm 60-75/min 5 Atrial fibrillation 5 Comment: For much of the trace the pacemaker is firing through both barrels, unaware that AF precludes any atrial capture. This wastes the battery. On the other hand, having a rapi
