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
Atrial Pacemaker Captures During 2:1 AV Block
Report: Sinus rhythm 0.5 AV sequential (known DDD) pacemaker 0.5 Atrial sensing & pacing 1.0”escape interval 1 AV interval 0.30” atrial-paced beats and one conducted sinus beat 1 Failed ventricular pacing 1 Second degree AV block 2:1 alternate paced
End-of-Life Pacemaker Function
Report:Sinus rhythm 75 – 77/min 1 Third degree AV block 2 Pacemaker rhythm 31/min 2 Probable battery depletion 5 Comment:Pacemaker interrogation revealed “end-of-life” battery function, set to bipolar VVI mode at 63/min, but obviously firing at half t
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
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
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 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
Pacemaker-Ventricular 2:1 Block
Report:Sinus rhythm 94/min 1 Atrial-sensing ventricular pacemaker rhythm 4 AV block (unspecified) 1 2:1 pacemaker-ventricular block 4 Comment:T wave’s more trouble than it’s worth. One cannot be sure whether we are dealing with sinus rhythm 94/min or
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
