Adenosine Asystole
Report:Atrial flutter 300/min High-grade (advanced) second degree AV block Transient asystole Ventricular escape beat Comment:The patient was admitted to CCU in flutter 310/min with 2:1 block (Fig 12a below). In all fairness, distinction from SVT cann
Not a Sinus Bradycardia
Report: Sinus rhythm Sinus arrest Junctional escape beats Retrograde conduction Non-phasic aberrant conduction Escape-capture bigeminy Comment: The phenomenon of escape-capture bigeminy depends on the coincidental arithmetic relationship between the
Xylocaine & BBBB
Report:Atrial tachycardia, possibly sinus, 174/min 2:1 AV block Left bundle branch block Period of 1:1 conduction Comment:The exact doubling and then halving of the ventricular rate should have steered the CCU staff away from xylocaine. Broad complex
4:2 AV Block?
Report:Supraventricular tachycardia, probably sinus, 132-150/min First degree AV block (PR 0.22â) Second degree AV block, Möbitz I Concealed AV conduction - Wenckebach with two blocked P waves 4:2 overall conduction ratio or, 2:1 AV block (unspec
Atrial Standstill & Idioventricular Rhythm
Report: Sinus arrest (atrial standstill) Idioventricular escape rhythm 10/min Comment: The amazing aspect of the patientâs extreme bradycardia was that she remained rousable with a pulse rate between 10 and 15/min in Casualty. Attempts to get all the
Rate-Dependent LBBB
Report: Sinus rhythm 90/min SVEBs, blocked, in bigeminy Left bundle branch block, rate-dependent Comment: The blocked atrial extrasystoles are discretely etched on the onset of the T wave. In the upper strip, the last LBBB complex has a distinctive nip
Agonal Rhythm
Report:Sinus bradycardia ?Shifting pacemaker SVEBs RBBB 3rd degree AV block. Ventricular standstill Comment:Normally, the right atrium is the last part of human heart to stop beating. This is not possible to diagnose from surface electrocardiogram
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
Complete Heart Block in Atrial Fibrillation
Report:Atrial fibrillation Third degree AV block Junctional escape rhythm 44/min LVH with ST/T changes ? incomplete LBBB Comment:At times there is a suggestion of flutter-like organised atrial activity, but the baseline is too variable for flutter. Th
Complete Heart Block in Atrial Flutter
Report:Atrial flutter 240/min Third degree AV block Junctional escape rhythm 36/min LVH with ST/T changes ? incomplete LBBB Comment:One would think the patient would have been paced by now. Perhaps there were sound clinical reasons for delaying the de
