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
Parasystole[!xe "Parasystole" \t "See Ventricular parasystole"!]
Report: Sinus rhythm Ventricular parasystole 41 - 43/min Comment: The diagnostic feature, unrecognised by the xylocaine pushers, is the variable coupling interval and the fixed interectopic one. And the fusion beat. Parasystole is, generally, resistant
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
AF with Regular Response?
Report: Atrial fibrillation Accelerated (idio)junctional rhythm Comment: Verapamil is known to âregulariseâ the ventricular response to atrial fibrillation. Completely regular rhythm, however, implies AV block and the presence of an escape pacemaker
Pseudoblock: Concealed Extrasystoles
Report: Sinus rhythm & arrhythmia Junctional premature beats Antegrade block in first and third manifest beats (blocked SVEBs) Concealed junctional extrasystole AV pseudoblock Incomplete RBBB Comment: Some junctional (presumably, main-stem, or bundl
Repetitive VT
Report:Sinus rhythm ? rate Borderline 1o AV block Repetitive VT 120/min Non-specific ST/T changes Comment:This patient later sustained acute inferior infarction (Fig 198a). The RCA was opened by PTCA and the ST segment elevation in the inferior leads
