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
Battery Depletion
Report: Atrial fibrillation 1 Third degree AV block 4 Pacemaker rhythm 44/min 1 Probable battery depletion 4 Comment: Most units are programmed to slow the basic rate as the battery becomes depleted; numbers vary. It is not certain, however, that batt
Pacemaker Completing the RBBB
Report:Sinus rhythm 70/min 1 Atrial pacemaker rhythm 55/min 2 Failure to sense 3 Capture beats 2 Right axis deviation +95o 1 Right bundle branch block 1 Comment:The atrial pacemaker discharges with complete regularity at 55/min, obviously heedless o
Termination of SVT: Pacemaker Escape
Report:Supraventricular tachycardia 165/min 1 Electrical alternans 2 Termination of paroxysm 0 Atrial escape beat (fusion) 2 Pacemaker escape beat 1 Sinus beat (fusion) 2 VEB (last complex) 1 Nonspecific ST/T changes, possible LVH (R2 = 15 mm) 1
Delectable Deductive Diagnosis of RBBB/LPHB
Report: Dual chamber pacemaker rhythm 70/min 2 Frontal plane axis –20o 2 Ventricular fusion complexes throughout 3 Probable underlying right bundle branch block with right axis deviation 3 Comment: I make no apologies for the subcontinental flavour of
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
Alternating Atrial Transport
Report: AV sequential pacemaker rhythm 78/min 4 Atrial capture in alternate cycles 3 Sinus ? atrial bigeminy in alternate cycles 3 Comment: Nobody would have looked hard at the atrial activity were the alternans not observed on the pressure display.
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
Another Proximal LAD Lesion
Report:Sinus tachycardia 133/min (Hyper)acute anterior infarction Comment:The indicative ST/T changes are in the anteroseptal leads and include lateral leads 1 and aVL. There is also marked reciprocal depression in the inferior leads. These are both sig
Double Interpolation
Report: Sinus rhythm 64/min 1 Pacemaker rhythm 62/min 1 Failure to sense (interpolated) 3 R-on-T pacing 2 Concealed retrograde conduction 3 Comment: The two rhythms, so to speak, pass through each other in a prolonged handover of the ventricles! Th
