Möbitz 2 Block with Narrow QRS Complexes
Report:Sinus rhythm 90/min Second degree AV block, Möbitz 2 Borderline ST segment depression Comment:This is quite unusual but fulfils perfectly the simplest and most useful definition of Type 2 block: all the PR intervals are the same. Below (Fig 144
Long Latency
Report: Sinus rhythm Latent (first degree) AV block PR 0.90” Left anterior hemiblock Right bundle branch block Old anterior infarction Comment: This is the longest sustained first degree AV block I have seen. It is possible that the rhythm is other
Cherchez le P!
Report: Sinus rhythm Second degree AV block, Möbitz 1 Acute inferior infarction Comment: The title is part Marriott’s famous phrase on how to tackle arrhythmias95; it paraphrases the once even more famous cherchez la femme, now squashed by the politica
PAT with Block: Pacemaker Lead
Report:Atrial tachycardia 138/min Second degree AV block, Möbitz 1; 2:1 & 3:2 block Right atrial electrode recording (bottom strips) Comment:The question is a "trick" one, designed to implicate the spurious change in the heart rate in the patient's pro
Classical Wenckebach Trigeminy
Report:Sinus rhythm 98/min Second degree AV block, Möbitz 1, with 4:3 conduction Trigeminy Left atrial abnormality (LAA) Left bundle branch block Atypical repolarisation pattern suggests ischæmia Comment:The Wenckebach sequences show the classical p
Post-Ectopic SA Depression Mime of SA Wenckebach
Report:Sinus rhythm 87/min SVEBs, blocked First degree AV block Right bundle branch block Comment:Acceleration before pauses is the hallmark of SA Wenckebach exit block. This would be a good example if the pauses were not generated by premature block
Junctional Escapes in Wenckebach Pauses
Report:Sinus rhythm Second degree AV block, Möbitz 1 Junctional escape beats Non-phasic aberrant conduction Comment:The ectopic complexes can be either premature or late (escape) beats. Here the Wenckebach pauses are interrupted by junctional escapes,
Vagal Vagaries
Report:Sinus rhythm Second degree AV block, Möbitz 1 Ventriculophasic effect in 2:1 conduction (top strip) Period of advanced (high-grade) second degree AV block Comment:Either Wenckebach (Möbitz 1) or Möbitz 2 AV block can progress from "low-grade"
Dual Conduction
Report:Sinus rhythm First degree AV block (PR intervals 0.24" and 0.40") SVEB (atrial premature beat, with P’R = 0.48” (?? blocked SVEB, with junctional escape) VEB Dual AV conduction (pathway) Comment:Manifest dual conduction13 in the same recordi
2:1 AV Block
Report:Sinus tachycardia 112/min 2:1 AV block Comment:The term "advanced" or "high-grade" AV block is used to describe 50% or less conduction. It is not a useful term except for the fact that it is used! Marriott is right in suggesting the term be used
