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
Agonal Rhythm
Report:Pacemaker rhythm 60/min 2 Absolute small voltage 3 Probable acute anterior infarction 5 Comment:There is probably an atrial standstill. The patient sustained clinical acute infarction and cardiogenic shock, dying within minutes of this trace b
Paced Bigeminy in PAT with Block
Report:Atrial tachycardia 146/min with block 2 100% paced atrial-sensing ventricular rhythm 97/min 3 Escape-capture bigeminy 5 Comment:This is a visually striking trace, with regular atrial tachycardia resulting in bigeminal paced ventricular rhythm. T
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
Atrial Pacemaker: First Degree AV Block
Report:Atrial pacemaker rhythm 90/min 4 AV interval 0.40 sec 2 Borderline intraventricular conduction delay (QRS 0.12 sec) 1 Inferior infarction, probably old 2 Nonspecific ST/T changes 1 Comment:The pacemaker is probably in the AAI mode; there is no
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
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
AV Pacemaker: No Ventricular Lead
Report:Atrial pacemaker rhythm 59/min 2 Right bundle branch block 2 AV interval 0.31” ?no ventricular lead 4 Q waves in 1, aVL, V5-6 – possible old anterolateral infarction 2 Comment:The diagnosis is suggested by the unusually long AV interval, althou
Failed Biventricular Pacemaker
Report:Sinus rhythm 63/min 1 Left atrial abnormality (LAA) 1 P wave 0.16” First degree AV block 3 PR 0.28” Right axis deviation +250o Left bundle branch block 3 Dual pacemaker, failed, 70/min 2 Comment:The combination of LBBB and RAD is virtually
Positive Concordant Precordial Pattern
Report:Pacemaker rhythm 63/min 2 1:1 retrograde conduction 3 Positive concordant precordial pattern 5 Comment:This is a temporary, bipolar unit, inserted in CCU. The patient had a very large right ventricle or the lead is inadvertently placed in the po
