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
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
Tricuspid Atresia
Report: Atrial pacemaker rhythm 111/min (dual chamber pacemaker) 4 Left axis deviation (LAD) –60o 3 LVH with ST/T changes 3 Comment: A cyanosed child with LAD most likely has tricuspid atresia; in one large series LAD was present in 87% of those wit
Atrial Sensing & Undersensing
Report:Atrial-sensing & pacing ventricular pacemaker rhythm 60/min 3 Atrial premature beats, possibly sinus 3 Blocked or sensed with first degree AV block or not sensed 3 Atrial bigeminy 1 Comment:All the QRS complexes are paced. The morphology of t
Pseudofusion Beats
Report:Atrial pacemaker rhythm 64/min 2 SVEB 3 Pseudofusion beats 4 Nonspecific ST/T changes 1 Comment:The QRS complexes are normal except for the ventricular pacing spikes at their onset. They are not fusion beats – the SVEB is preceded by an atrial
Paced Tricuspid Atresia
Report:Atrial pacemaker rhythm 111/min Left axis deviation â60o Left ventricular hypertrophy with ST/T changes Comment:The child had Fontan repair119 (atriopulmonary connection) in infancy. His combination of LVH and LAD is characteristic of tricus
Complete Chest Lead Reversal
Report:Atrial pacemaker rhythm 78/min Complete chest lead reversal Possible left ventricular hypertrophy Comment:This is a rare variant of lead reversal. It happens when the entire block of V-lead terminals is rotated 180o and inserted into the machine
Atrial Fusion Beats
Report:Sinus rhythm Junctional ? atrial rhythm Shifting (atrial) pacemaker Atrial fusion beats AV dissociation Probable third degree AV block Pacemaker rhythm 63/min Comment:Again, this is a "trick" question, designed to make one look (in vain) for
Sinoatrial Block: CVA
Report:Sinus rhythm Sinus pauses - probable Wenckebach exit block Junctional escape beats and rhythm Atrial fusion beats SVEB. Comment:The sinus cycles tend to shorten before the pause, a characteristic of Möbitz 1 (Wenckebach) exit block. There is
Congenital Complete Heart Block: Ventriculophasic Sinus Arrhythmia
Report:Sinus rhythm 67 â 70/min Third degree AV block Junctional escape rhythm 42/min Ventriculophasic sinus arrhythmia Right atrial abnormality (RAA) Comment:The ventricular rate is regular and slow, the faster P waves completely dissociated: comp
