Interpolated VEBs & Couplets
Report:Sinus rhythm VEBs, some interpolated, some (bottom strip) in couplets (pairs) Comment:In the top strip, the first VEB blocks the ensuing sinus P wave, creating a fully compensatory pause. The other two penetrate the AV junction retrogradely (conc
R-on-P Bigeminy
Report:Sinus rhythm 93/min First degree AV block (PR 0.28â) VEBs, bigeminal Early transition (counterclockwise rotation) Nonspecific ST/T changes Comment:The VEBs are easily recognised for what they are, with obvious dissociation from the preceding
Idioventricular Rhythm in Advanced AV Block
Report: Sinus rhythm Advanced (high-grade) second degree AV block Left bundle branch block Idioventricular escape rhythm Right bundle branch block morphology Ventricular fusion beats Comment: The escape rhythm originates from the distal left bundle
Reentry (Echo) Beats of Ventricular Origin
Report: Sinus rhythm VEBs Bigeminal Couplets & triplets Retrograde VA conduction First degree VA block Wenckebach conduction Reentry Post-ectopic sino-atrial depression Junctional escape beats Comment: There are two reentry beats: third last in
VEB-Induced AV Block
Report: Sinus rhythm. VEBs Second-degree AV block, advanced. Junctional escape beats. Intraventricular conduction delay, QRS 0.12". Comment: All the occurrences of the AV block follow the VEBs. This is âan extremely rare phenomenonâ, with only th
Atrial or Ventricular Fibrillation?
Report: Top: Atrial fibrillation with third degree AV block, or ventricular fibrillation Ventricular standstill Middle: Atrial fibrillation Third degree AV block Junctional rhythm 68/min Bottom: Sinus rhythm 98/min Third degree AV block Junction
Alternate Cycle Antecedent P Waves
Report:Ventricular tachycardia 125/min Probable 2:1 retrograde conduction Comment:The diagnosis of VT is supported by the QRS duration of 0.18â, the indeterminate abnormal axis and the left rabbit ear in V1 being taller than the right. The relativel
Escape-Capture Quadrigeminy
Report: Sinus rhythm First degree AV block (PR 0.28â) Incomplete right bundle branch block (Slightly) accelerated ventricular (fascicular) rhythm 69 - 72/min Sinus capture beats Comment: The PR interval would probably be shorter without the inter
Accelerated Idioventricular Rhythm in Complete AV Block
Report: Sinus tachycardia 120/min Accelerated idioventricular rhythm 65/min Third degree AV block Comment: One can confidently diagnose complete AV block when the atrial rate is so much faster than the ventricular, without any captures, the ventricular
Complex Complex of Complex Complexes
Report: Ventricular (fascicular) tachycardia 139/min Retrograde VA block , Möbitz 1 Incomplete Wenckebach sequences Reentry (echo) beats of ventricular origin Comment: As shown on the laddergram below, the longest retrograde RP interval in each tripl
