LBBB-Like VT in Patient with LBBB
Report:Ventricular tachycardia 125/min 1:1 retrograde conduction Spontaneous termination Sinus rhythm VEBs, one couplet Comment:The QS complexes in V1 take a very long time to reach the S wave nadir; the upstroke is quite sharp. This is the only reli
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
Bigeminal Ménage à Trois
Report: Sinus tachycardia 105/min Intraventricular conduction delay QRS 0.12â VEBs, couplets Bigeminy Ventricular fusion beats Comment: The conducted sinus beats, with the VEBs, come in three varieties: âpureâ sinus or âpureâ ectopic bea
AV Dissociation in VT
Report: Sinus tachycardia 127/min Left atrial abnormality (LAA) First degree AV block (PR 0.22â) Axis -100o (Northwest, no-manâs land, ânonsenseâ axis) Probable left anterior hemiblock Right bundle branch block VEB, probably fusion beat (5th
VEBs: (Con)fusion Bigeminy
Report: Sinus rhythm VEBs, late-diastolic, in bigeminy Ventricular fusion beats Comment: There are, depending on the VEBsâ timing, different degrees of fusion. Note how the sinus contribution is proportional to the PR interval of the fusion beat: t
VEBs: Couplets & Concealed Retrograde Conduction
Report: Sinus rhythm Left atrial abnormality (LAA) PR interval 0.20â Intraventricular conduction delay (QRS 0.12â) VEBs in couplets Triplet (or more, end of bottom strip) of ventricular tachycardia 102/min Concealed retrograde conduction Comm
VT, then SVT
Report: Sinus rhythm 90/min PR 0.20â Triplet of polymorphous ventricular tachycardia 120/min 5-beat run of atrial tachycardia 118/min Left anterior hemiblock Old anterior infarction Comment: Following the VT, an atrial escape beat is followed b
Complex Trigeminy: Quadrigeminy in Disguise
Report: Sinus rhythm 73/min VEB couplets in trigeminy Ventricular fusion beats (second in each couplet) Concealed retrograde conduction Comment: The first VEB is interpolated between the preceding sinus beat and a fusion beat; hence the fusion beats h
Ventricular Fusion Rhythm
Report: Sinus rhythm Accelerated idioventricular rhythm (AIVR) AV dissociation Ventricular fusion beats Comment: The periods of AIVR in the upper strips are introduced or terminated by fusion complexes; the 8-beat run in the bottom strip consists enti
Ventricular Fibrillation
Report: Sinus tachycardia 118/min VEB Ventricular fibrillation DC cardioversion artefact (middle of third strip) CPR artefact Junctional rhythm Sinus rhythm and tachycardia, VEB & SVEBs (bottom strip) Marked ST segment elevation post-cardioversion
