Escape-Capture Bigeminy in AF
Report: Atrial fibrillation 1 High-grade or complete AV block 1 Junctional rhythm 2 Pacemaker rhythm 1 Escape-capture bigeminy 1 Left anterior hemiblock (LAHB) 1 Right bundle branch block 1 Anteroseptal infarction, age uncertain 1 ST/T changes con
Failure to Sense
Report:Atrial fibrillation 1 Ventricular pacemaker 1 Failure to sense 2 R-on-T pacing 2 Fusion beat 2 Incomplete right bundle branch block 1 Nonspecific ST/t changes 1 Comment:Failure to sense is only intermittent, since the pacemaker discharge is
Another Paced Bigeminy
Report:Sinus rhythm 88/min 1 AV block, unspecified 1 DDD pacemaker rhythm 62/min 1 Alternating atrial sensing and pacing 2 Failure to sense alternate P waves 2 Atrial trigeminy 1 Ventricular bigeminy 1 Posterior electrode position 1 Comment:The se
Agonal Pacemaker Rhythm
Report: Pacemaker rhythm 80/min 4 Broad pacemaker complexes 0.36” suggest hyperkalæmia or agonal rhythm 6 Comment: It was the latter – agonal rhythm. I rang the patient’s physician who told me the patient had by then been allowed to die, in cardiogenic
Atrial Sensing and Pacing
Report:Sinus rhythm 75/min 1 VEB 1 Atrial-sensing ventricular pacemaker 3 Atrial sensing and pacing ventricular pacemaker (last beat) 4 Left atrial abnormality (LAA) 1 Comment:This is a DDD pacemaker, responding to both the atrial activity and the la
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
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
Atrial-Sensing Pacemaker in AF
Report: Atrial flutter/fibrillation 2 Dual-chamber pacemaker 3 Tachycardia up to 129/min due to atrial (over)sensing 5 Comment: The pacemaker is programmed to follow – up to a set upper rate limit – atrial activity. This is really meant for sinus rhyth
Spiky Ventricular Tachycardia
Report: Pacemaker-mediated tachycardia 118/min 10 Comment: In view of the identical complexes in the admission ECG (Fig 81a) it is hard to believe that Casualty staff thought they were treating a genuine VT with amiodarone. Not to mention the same pacing
Establishing Pacemaker Dependence the Hard Way
Report: Sinus rhythm 1 Third degree AV block 3 Idioventricular rhythm 2 QT interval 0.86” 1 Sinus arrest 2 Pacemaker rhythm 1 Comment: The surgeon, who got rather flustered when told the heart had stopped, certainly established the diagnosis of thi
