Alternating Paced and Fusion Beats
Report: Slow atrial or junctional rhythm 38/min 2 Ventricular pacemaker rhythm 79/min 2 Superior electrode placement 2 Fusion in alternate beats 2 Presumptive RBBB 1 ST/T changes of uncertain significance 1 Comment: The narrower (0.12 sec) complexes are p
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
Trigeminy
Report: Demand pacemaker rhythm 65/min 2 Hysteresis rate 60/min 3 Intermittent retrograde conduction 2 Sinus capture beats 2 Trigeminy 1 Probable sick sinus syndrome 0 Comment: To comment on the appropriateness of the pacing rate one has to know th
Unusual Mechanism of Escape-Capture Bigeminy
Report: Sinus rhythm 0.5 SVEBs, blocked, in (atrial) trigeminy 2 AV sequential pacemaker, atrial-sensing (probably DDD) 0.5 Failure to sense SVEBs 4 Atrial-paced escape beats 0.5 Ventricular bigeminy (atrial trigeminy!) 2 Nonspecific T wave changes
AV Dissociation with Interference
Report:Sinus rhythm 1 Borderline right atrial abnormality (RAA) 1 SVEB 1 Ventricular demand pacemaker rhythm 72/min 2 AV dissociation with interference 2 Fusion beat 2 Nonspecific ST/T changes 1 Comment:The sinus P waves march through the first fo
Sinus Bradycardia: Escape-Capture Bigeminy
Report:Sinus bradycardia 38/min 3 Ventricular pacemaker escape beats 2 Escape-capture bigeminy 4 Nonspecific ST/T changes 1 Comment:A precondition for escape-capture bigeminy is a very long effective supraventricular cycle, created in this instance by
Rate Hysteresis
Report:Sinus rhythm 1 VEBs, multiform 2 Demand ventricular pacemaker 3 Rate hysteresis 3 Fusion beat (top panel) 1 Comment:The VVI pacemaker takes over after the VEBs; the long cycle it terminates corresponds to a rate 50/min, while the subsequent t
Sinus Bigeminy: Sick Sinus Syndrome
Report: Sinus rhythm 1 Bigeminy, probably due to 3:2 sinoatrial exit block 2 Demand pacemaker, bigeminal fusion beats 7 Comment:The differential diagnosis for this rhythm includes sinus extrasystoles, with post-ectopic SA depression, and atypical sinu
Pacemaker: Escape-Capture Bigeminy
Report:Sinus tachycardia 100/min First degree AV block (PR 0.28") Second degree AV block. Right bundle branch block Pacemaker (escape) beats Escape-capture bigeminy Comment:Before Bradley and Marriott's classical description6, this rhythm was called
Pacemaker-Sinus Escape-Capture Bigeminy
Report: Sinus rhythm Second degree AV block, unspecified Intraventricular conduction delay (QRS 0.12") Pacemaker escape beats Escape-capture bigeminy Comment: The conducted sinus beats have normal PR intervals, but the P waves following them have the
