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
Skipped and Blocked SVEBs
Report:Sinus tachycardia 100/min Blocked atrial premature beats interrupting Wenckebach sequences Over the top conduction (skipped Pâ waves) Post-ectopic sinoatrial depression VEB Left atrial abnormality (LAA) Small voltage in frontal leads Nonsp
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
Möbitz 2 AV Block & Right Bundle Branch Block
Report:Sinus rhythm 90/min Second degree AV block, Möbitz 2 Right bundle branch block Borderline left atrial abnormality (LAA) Comment:All the PR intervals, before and after the block, are 0.16â. This is type 2 block, intraventricular: the LBB is b
Concealed Extrasystoles & Pseudoblock
Report:Multifocal atrial rhythm VEBs, multiform Fusion beat Second degree AV block, probable pseudoblock Comment:This would have been a multifocal atrial tachycardia (MAT) if the rate was over 100/min. AV block is uncommon in MAT and should be even le
Dual Conduction
Report:Sinus rhythm First degree AV block (PR intervals 0.24" and 0.40") SVEB (atrial premature beat, with PâR = 0.48â (?? blocked SVEB, with junctional escape) VEB Dual AV conduction (pathway) Comment:Manifest dual conduction13 in the same rec
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
Concealed Conduction: Atrial Flutter
Report:Sinus rhythm Left atrial abnormality (LAA) Second degree 2:1 AV block Atrial flutter 300/min Third degree AV block Idioventricular escape rhythm 41/min Inferoposterolateral MI, age uncertain, probably old Comment:The flutter maintains a stat
Sino-Atrial Wenckebach
Report:Sinus rhythm Sino-atrial exit block, Möbitz 1 Left atrial abnormality (LAA) AV block, Möbitz 1, incomplete sequences Prolonged QT interval Comment:This is an example of one form of block preventing the full expression of another: the AV nod
Scary Pauses in Congenital AV Block
Report:Sinus arrhythmia Third degree AV block Junctional escape rhythm 5.52" pause Comment:Most patients with (idiopathic) congenital heart block have a reasonably fast junctional pacemaker and can get by without pacing. Presence of prolonged pauses m
