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
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
Respiratory & Ventriculophasic Sinus Arrhythmia
Report: Sinus rhythm Respiratory sinus arrhythmia Ventriculophasic sinus arrhythmia Second degree AV block, Möbitz 1 Period of 2:1 conduction + one 5:4 cycle LVH with ST/T changes ± digoxin effect Comment: The ventriculophasic effect â P-P inter
Idioventricular Rhythm in Complete AV Block
Report: Sinus arrhythmia & bradycardia Junctional rhythm 48/min, also blocked Third degree AV block Idioventricular escape rhythm 10 â 30/min Comment: The (blocked) sinus rhythm is slow and irregular. Eventually it is replaced by somewhat more const
Interpolated VEBs in Advanced AV Block
Report: Sinus tachycardia 108/min Second degree, advanced (4:1, 3:1) AV block VEBs, multiform, interpolated Left bundle branch block Comment: The ætiology of the block remained unknown; it could have been due to polyarteritis nodosa through its assoc
Trigeminal Bradycardia
Report: Sinus tachycardia Advanced second degree AV block 9 second pause Junctional escape beats Comment: Some sinus beats are probably conducted, e.g., first two in the top strip. The long pause is terminated by a junctional escape (first beat in the
Advanced AV Block Following VEBs
Report: Sinus rhythm VEBs Triplet of ventricular tachycardia Advanced second degree AV block Comment: The episodes of ventricular standstill all follow the VEBs. The VEBs appear to have retrograde conduction, which may account for sinus rates being
