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
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
Iatrogenous 1o AV Block
Report: Sinus rhythm 62/min 1 DDD (universal) pacemaker Atrial-sensing, ventricular-pacing mode 3 Atrial under-sensing in V1-3, with atrial + ventricular paced complex 3 Long A-V interval 0.30” 3 Comment: In programming the A-V sequential pacemakers
Isorhythmic Dissociation of a VVI Pacemaker
Report:Sinus rhythm 70/min 1 Ventricular pacemaker rhythm 70/min 4 AV interval 0.36 sec 5 Comment:The sinus P waves are not very well shown in the frontal leads, but there’s no doubting them in the chest leads V1-3. The AV interval is long, but constan
