Sinus Tachycardia with Unusual Bigeminy
Report: Sinus tachycardia 112/min First degree AV block Second degree AV block[!xe "AV block:second degree:2-1 advanced" \b!] 2:1 in top & bottom strips Advanced in middle strip Junctional escape beats Escape-capture bigeminy [!xe "Escape-capture b
R-on-T VEB: Ventricular Fibrillation
Report: Sinus rhythm 92/min (top) R-on-T VEB Ventricular fibrillation DC defibrillation (third strip) Post-countershock sinus bradycardia, VEB Sinus tachycardia 115/min (bottom) Comment: A reperfusion arrhythmia is not expected a day after. At any r
Sinus-Junctional Escape-Capture Bigeminy
Report:Sinus rhythm 84/min Borderline left atrial abnormality (LAA) Second degree AV block, unspecified Junctional escape beats Escape-capture bigeminy LVH with ST/T changes Comment:Only every third sinus P wave is conducted, with a PR interval just
Ventricular Standstill in Sinus Tachycardia
Report:Sinus tachycardia 113/min Second degree, mostly 2:1 AV block Complete AV block â ventricular standstill Intraventricular conduction delay (known LBBB) Comment:This is almost certainly Möbitz 2 AV block in view of the associated bundle branch
Slow Junctional Escape in Complete AV Block
Report:Sinus rhythm 90/min Third degree AV block Junctional escape rhythm 19/min Anterior infarction ? incomplete LBBB QT/T wave changes consistent with ischæmia or preceding syncope. Comment:As in the previous case, the escape pacemaker, although a
Dig the Break!
Report: Sinus rhythm 96/min Second degree AV block, 2:1[!xe "AV block:concealed:dig the break" \b!] SVEB[!xe "SVEBs:unmasking 2o AV block" \b!] Left bundle branch block Comment: The blocked alternate P waves are almost completely hidden by the descend
Atrial Fibrillation with Complete AV Block
Report:Atrial fibrillation Third degree AV block VEB Junctional escape rhythm 42/min Possible old inferior MI Diffuse ST/T changes Comment:The ventricular rate is completely regular and slow, disturbed only by a single VEB. The VEB looks like LBBB,
Alternating Retrograde Conduction in Accelerated Junctional Rhythm
Report:Accelerated junctional rhythm 92/min 2:1 retrograde block Right axis deviation Lateral infarction, acute or recent Borderline small voltage in frontal leads Electrical alternans V1 Comment:One would be tempted to say that this trace is an exa
Sinus Bigeminy
Report: Sinus rhythm 98/min (top) Sino-atrial 3:2 Möbitz 1 exit block?[!xe "Sino-atrial exit block:bigeminy" \b!] Bigeminy[!xe "Bigeminy:sinus" \b!] Comment: The differential diagnosis includes SVEBs in bigeminy (where Pâ waves look different to sin
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
