3:2 Möbitz 2 AV Block
Report: Sinus tachycardia 106/min Left atrial abnormality (LAA) Möbitz 2 second degree AV block, 3:2 conduction, with bigeminy Indeterminate axis â140o Right bundle branch block Anteroseptal infarction, probably old Comment: In all instances of t
Congenital Heart Block
Report: Respiratory and ventriculophasic sinus arrhythmia Right atrial abnormality (RAA) Left atrial abnormality (LAA) Second degree AV block, unspecified Junctional rhythm 65/min AV dissociation with interference Comment: Congenital heart blocks ar
Long Wenckebach Pauses
Report: Sinus rhythm 56 â 66/min Second degree AV block, Möbitz 1 3:2 conduction with bigeminy Left ventricular hypertrophy voltage Comment: Wenckebach pauses are normally less than two sinus cycles in length. When, as here, they coincide with the
Sudden Ventricular Standstill
Report: Sinus tachycardia 100/min Borderline first degree AV block Left bundle branch block Third degree AV block Ventricular escape beats (bottom) Comment: This is a typical example of AV block in acute anterior infarction: RBBB or LBBB (as here) fo
Alternate-Beat Wenckebach Caused by VEBs
Report:Sinus rhythm 92/min VEBs, couplets and triplets R-on-T phenomenon Wenckebach second degree AV block for alternate P waves Acute or recent inferior infarction Comment:The first two consecutively conducted P waves show slight but definite PR int
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
Sinus Arrhythmia or SA Exit Block?
Report: Sinus rhythm Sino-atrial exit block Comment: All the groups display the characteristic acceleration before the pause. This is the hallmark of Wenckebach (Möbitz 1) sino-atrial exit block, only slightly modified by true (respiratory) sinus arrhy
