Complete AV Dissociation
Report: Pacemaker rhythm 80/min 3 Sinus rhythm, non-conducted, 85/min 3 Complete AV dissociation 3 Left atrial abnormality (LAA) 1 Comment: The paced complexes have the typical LBBB/LAD appearance, indicating pacing from the apex of the right ventricl
Atrial Sensing & Undersensing
Report:Atrial-sensing & pacing ventricular pacemaker rhythm 60/min 3 Atrial premature beats, possibly sinus 3 Blocked or sensed with first degree AV block or not sensed 3 Atrial bigeminy 1 Comment:All the QRS complexes are paced. The morphology of t
The Commonest Cause of a Pause
Report:Sinus tachycardia 100/min 1 Atrial-sensing ventricular pacemaker rhythm 1 Blocked SVEB 6 Left atrial abnormality (LAA) 1 Right bundle branch block 1 Comment:There is a subtle but definite change in the T wave of the last paced beat before the
Controlling the Ventricular Rate: PVARP
Report:Atrial tachycardia 222/min (? slow flutter) with 2:1 block 4 LVH with ST/T changes (incomplete LBBB) 1 Atrial-sensing electronic pacemaker firing 111/min 1 Pseudofusion beats 4 Comment:The atrial tachycardia is somewhat discreet, but two atrial
Pacemaker Syndrome: Paced Bigeminy
Report:Pacemaker rhythm 71/min 1 AV sequential (probably DDD) pacemaker 2 Reentry paced beats of pacemaker origin 5 Bigeminy 1 No evidence of paced atrial capture 1 Comment:The trace should be compared to the previous one, where each atrial pacing sp
Symptomatic Bigeminy Due to Trigeminy
Report: Sinus rhythm 80/min 1 Blocked SVEBs, trigeminal 8 A-sensing ventricular pacing throughout 1 Comment: Not surprisingly, the pacemaker was blamed. It was programmed to pace at 60/min, with a sleep mode of 50/min during night hours. There was no
Low-Atrial Pacemaker
Report:Atrial pacemaker rhythm 70/min 2 Retrograde P wave pattern 7 Nonspecific T wave changes 1 Comment:At first I thought the electrode had been inserted into the coronary sinus. It turned out the heart had been paced more conventionally through the
Fully Compensatory Pause: Post-Ectopic SA Depression
Report:Sinus rhythm 80/min 1 Left atrial abnormality (LAA) 2 SVEB with (fully) compensatory pause 3 Atrial-sensing ventricular pacing with 100% capture 4 Comment:The SVEB, probably of atrial origin, causes a fully compensatory pause – exactly the len
Atrial Pacemaker Rhythm: Wenckebach Periods
Report:Dowling Dennis Raymond 55 15/4/00 106504Atrial pacemaker rhythm 89/min 2 Second degree AV block, Möbitz 1 5 Left ventricular hypertrophy with ST/T changes 2 Probable old inferior infarction 3 Comment:The spike-to-R interval (equivalent of PR o
Atrial Pacemaker: Failure to Sense
Report:Sinus rhythm 89/min 1 PR interval 0.20 sec 1 Atrial demand pacemaker 3 Intermittent failure to sense 4 Right bundle branch block 1 Comment:There are three atrial pacemaker beats. All three have a very early spike, always in the same spot. Th
