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-grad
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
Complete AV Block
Report:Third degree AV block Sinus bradycardia 42/min Junctional beats (top strip) Atrial fibrillation Junctional escape rhythm 36/min Pacemaker rhythm 82/min Short QT interval ? digoxin toxicity Comment:The varied atrial activity has no effect on
Ventriculophasic Sinus Arrhythmia
Report:Sinus rhythm. Second degree AV block, Möbitz 1 Ventriculophasic sinus arrhythmia. Phasic aberrant conduction Comment:The âshortâ complexes are aberrantly conducted sinus beats. The promotion from 2:1 to 3:2 block has produced a long-short
Carotid Sinus Massage: 2o AV Block
Report: Sinus rhythm ?Accelerated conduction (PR interval 0.11â) Second degree AV block Comment: The massage was performed in the hope of unmasking WPW conduction, of which there is a soupçon in the initial slurring of the QRS. Instead of broadening
