DDD Pacemaker in Acute Infarction with 2:1 AVB
Report:Sinus tachycardia 124/min 2:1 AV block A-sensing ventricular pacemaker rhythm 62/min Fusion beats Acute or recent inferolateral infarction Comment:My first thought was something exotic: accrochage between the temporary pacemaker and the sinus
Temporary AV Pacemaker
Report:Upper strips: Ventricular lead off Atrial pacemaker rhythm 80/min Loss of capture with reduced output Escape sinus bradycardia Resumption of capture at treshhold output Lower strip: Atrial pacemaker rhythm 53/min Failure to pace in two cycl
Beginning of an Endless Loop
Report: Sinus rhythm 79/min 1 VEB 1 Ventricular escape beat, preceded by attempt at atrial pacemaker escape 1 VEBs, dimorphic couplet 1 Retrograde conduction 2 Retrograde P sensing and generating pacemaker tachycardia 103/min 4 Comment: The retrogra
Runaway Pacemaker
Report: Pacemaker tachycardia 180/min 5 Runaway pacemaker 5 Comment: Most modern pacemakers would have a ventricular rate-limiting mechanism to prevent this degree of tachycardia. The trace itself does not offer any clues as to the cause: all one can se
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
Pacemaker Confusion in Pseudofusion: Transposition of Great Vessels
Report: Sinus tachycardia 110/min 1 Left atrial abnormality (LAA) 1 Indeterminate abnormal axis ±194o 2 Right ventricular hypertrophy 3 Pacemaker sensing spikes (pseudofusion beats) 3 Comment: The spikes occur after the onset of the QRS complex, pr
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
Discrete Lateral Infarction
Report:Sinus rhythm 53/min Acute (high) lateral infarction Comment:It often the case that in (high) lateral infarctions the most prominent early feature is the reciprocal change in the inferior leads. However, whenever ST segment elevation and depressio
PseudoWenckebach in Ventricular Pacemaker
Report:Sinus tachycardia 122/min. 1 Möbitz 1 AV block, 5:4 and 4:3 conduction. 2 Atrial-sensing ventricular pacemaker (probably a DDD pacemaker). 3 Pseudo-Wenckebach. 4 Comment:The ventricular complexes are all paced and all identical, indicating no a
Atrial-Triggered Failed Pacemaker
Report:Sinus rhythm 94 - 96/min 1 First degree AV block (PR 0.28") 2 Left atrial abnormality (LAA) 1 Atrial-triggered ventricular pacemaker 2 Failure to pace 3 LVH with ST/T changes (incomplete LBBB) ± ischæmia 1 Comment:The pacing spikes bear const
