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
VVI Pacemaker Mime of Atrial Sensing
Report:Pacemaker rhythm 70/min 4 Atrial tachycardia/flutter 210/min 6 Comment: The patient had a VVI pacemaker set at 70/min, precisely because she had almost constant atrial tachyarrhythmias. In this tracing, however, the AV interval appears fixed at
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
Sensing but not Pacing
Report:Sinus rhythm 100/min 2 2:1 AV block 3 Left atrial abnormality (LAA) 1 Failure to pace in atrial-sensing pacemaker 3 Prolonged QT interval 0.56” 1 Comment:The unit is almost certainly a DDD one, with preserved atrial sensing but no ventricular
Sinus Captures with 1o AV Block
Report:Sinus rhythm approx. 86/min 1 Second degree AV block, unspecified 2 AV pacemaker rhythm 60/min 1 No atrial capture 2 Sinus captures with 1o AV block 2 Left anterior hemiblock + IVCD 1 LVH with ST/T changes 1 Comment:The space between the atr
Ectopic Pacemaker
Report:AV pacemaker rhythm 59/min; AV interval 020” (as programmed) 0.5 Displaced ventricular lead 3 Intermittent failure to pace & native QRS conduction at spike-R interval 0.36” 4 Failure to sense (the delayed atrial-paced native QRS) 2 ST/T changes
Pacemaker Tachycardia with Spike Alternans
Report:AV sequential pacemaker tachycardia 120/min 8 Pacemaker spike alternans 2 Comment:The patient refused to stay in Casualty and went home. He returned several days later, when his pacemaker was “interrogated”. No malfunction was found in this DDDR
Onset of Pacing With Retrograde Conduction
Report:Sinus rhythm 59-62/min 1 Borderline left atrial abnormality (LAA) 1 Demand pacemaker rhythm 59/min 3 Retrograde conduction 5 Comment:The slight sinus arrhythmia allows the pacemaker takeover at 59/min, following a pseudofusion beat in the midd
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
Atrial Pacemaker & WPW Conduction
Report: Atrial pacemaker rhythm 71/min 3 WPW ‘B’ conduction 7 Comment:The AV (i.e., spike to QRS) interval here is about 0.15”, but the atrial wave itself hugs the QRS complex as expected. It is invisible in some leads (e.g., V3-6) because it is not a
