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
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
QRs VEBs in V1
Report: Sinus rhythm VEBs, late-diastolic, in bigeminy Comment: The VEBs have an Rs morphology; the Q wave is in fact a superimposed, dissociated sinus P wave. The dissociation is incomplete in the case of the 6th and the 10th complex, where âa tad of
Sinus Captures in Nodal Rhythm
Report: Junctional rhythm 42/min Sinus capture beats AV dissociation with interference Concealed conduction Comment: The sinus captures are only possible after sufficient distance from the preceding QRS complex has rendered the AV node amenable to con
Xylocaine Tachycardia
Report:Sinus tachycardia 114/min (middle strip) SVEBs Blocked, in bigeminy (top) Aberrantly conducted, in bigeminy (bottom) Comment: Xylocaine has some atropinic effect and may have facilitated AV conduction, impairing at the same time the intraventr
AIVR & Retrograde Conduction
Report: Sinus arrhythmia VEB (second complex in the top strip) Atrial (?junctional) escape complex (9th in the top strip) Accelerated idioventricular rhythm 86-89/min Retrograde conduction Fusion beats Comment: Typically, the retrograde 1:1 conducti
Aberrant Reentry Beats of Junctional Origin
Report: Sinus bradycardia 36/min (middle & end of bottom strip) Sinus arrest, possibly exit block Junctional escape rhythm Reentry (echo) beats of junctional origin Retrograde first degree VA block 0.26â Antegrade first degree AV block 0.26â Lef
