Concealed Non-Conduction
Report: Atrial tachycardia 186/min 3:1 AV block Comment: Can one really tell? The descent of some T waves is sharper than expected or shallowly notched; the same cycles also have a notch immediately following the end of the preceding QRS complex. Someth
Second Degree AV Block
Report: Sinus rhythm One cycle episode of second degree AV block Comment: The patient kept no diary, but it is safe to presume she was asleep at 4 am. What is one to make of her blocked P waves (there was another, below)? Probably nothing, given that no
Wenckebach AV Block in Sinus Tachycardia
Report: Sinus tachycardia 106/min Right atrial abnormality (RAA) Second degree AV block, Möbitz 1 Up to 0.48â PR Intervals Junctional escape beat (third last QRS) LVH with ST/T changes Comment: The 4:3 and 5:4 Wenckebach cycles seen from beginni
Wenckebach AV Block in Marked Sinus Tachycardia
Report: Sinus tachycardia 138/min Second degree AV block, Möbitz 1 Probable acute inferior infarction Comment: It is unwise, generally, to diagnose infarction from rhythm strips, but this one has all three indicative changes of acute infarction: Q wav
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
Notched P Wave
Report: Sinus rhythm Left atrial abnormality (LAA) Widely notched P wave Sino-atrial exit block Probable atrial infarction Comment: The wide P wave (0.18â) is produced by an atrial conduction defect, usually involving the interatrial tract (Bachm
Sinus Rhythm Faster Than Itself
Report: Nonparoxysmal junctional tachycardia (NPJT) 98-100/min Sinus rhythm 94-96/min Left atrial abnormality Sinus capture beats AV dissociation with interference Left ventricular hypertrophy with ST/T changes (incomplete LBBB) Comment: Paradoxical
VEBs: Concealed Retrograde Conduction
Report: Sinus rhythm Left atrial abnormality VEBs, uniform; couplets[!xe "VEBs:concealed conduction:couplets" \b \i!][!xe "VEBs:couplets" \b \i!] Concealed retrograde conduction Comment: Despite a slight sinus arrhythmia it is possible to map out un
SVEBs in Bigeminy or 2:1 AV Block?
Report: Sinus rhythm 72/min Second degree AV block, 2:1 Ventriculophasic sinus arrhythmia Left bundle branch block Comment: The ventriculophasic effect is so marked that one cannot be completely certain that the atrial complexes at the end of T wave
Möbitz 2 AV Block
Report: Sinus rhythm Advanced second degree AV block, Möbitz 2 Ventricular pacemaker Intermittent failure to xsense Intraventricular conduction defect, unspecified Comment: The pacemaker was stopped after the first beat in the upper strip, turned on
