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
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
Sino-Atrial Exit Block
Report:Sinus rhythm 52 â 54/min Sino-atrial exit block Bigeminy Nonspecific T wave changes Comment:There are two long cycles. One is slightly longer, the other slightly shorter than twice the preceding P-P cycle. Allowing for some sinus arrhythmia,
Ventricular Escapes in Wenckebach Pauses
Report: Sinus rhythm Second degree AV block, Möbitz 1 (Wenckebach)[!xe "AV block:second degree:Möbitz 1:ventricular escape beats" \b!] VEBs[!xe "VEBs:escape beats:accelerated, in 2o AV block" \b!] Comment: The VEBs increase the length of Wenckebach p
Failed Pacemaker?
Report: Sinus tachycardia 104 - 124/min First degree AV block[!xe "PR interval:long" \t "See AV block, first degree"!] Second degree AV block, probably Möbitz 2 Third degree AV block Ventricular standstill Junctional escape rhythm, ventricular escap
Unusual Wenckebach Sequences
Report:Sinus arrhythmia Second degree AV block, Möbitz 1 Bradycardia-dependent LBBB (4th beat in the top strip) ? Respiratory artefact ? Bradycardia-dependent incomplete LBBB ? Junctional escape beats with non-phasic aberrant conduction Comment:T
Verapamil Wenckebach
Report: Sinus rhythm Möbitz 1 (Wenckebach) second degree AV block Comment: This is a very low-grade block and the patient is monitored anyway. Nothing needs be done immediately. In the long term, an antihypertensive without AV blocking properties shoul
