Sinoatrial Block: CVA
Report:Sinus rhythm Sinus pauses - probable Wenckebach exit block Junctional escape beats and rhythm Atrial fusion beats SVEB. Comment:The sinus cycles tend to shorten before the pause, a characteristic of Möbitz 1 (Wenckebach) exit block. There is
Empty Wenckebach Pauses
Report: Sinus rhythm SVEB (second QRS, bottom strip) Second degree AV block, Möbitz 1 Junctional beats, non-conducted ?Reentry beats of sinus origin Atrial fusion beats, non-conducted Comment: In the upper strips, the Wenckebach sequences are termi
Non-Sustained Ventricular Tachycardia: Fusion and Narrow Capture Beats
Report:Sinus tachycardia 108/min Runs of ventricular tachycardia 134/min Fusion beats Possible old inferior infarction Nonspecific ST/T changes Comment:The diagnosis of ventricular tachycardia is based on (i) R or qR complexes in V1; (ii) A-V dissoci
Accelerated Idioventricular Rhythm
Report:Accelerated idioventricular rhythm 96/min AV dissociation Fusion beat Sinus rhythm 98/min Anterior infarction ?age Comment:This has, at times, been called slow VT. There is no such thing: the term is a contradictio in adjecto. There can be no
Fusion VEBs in Trigeminy
Report:Sinus tachycardia VEBs in trigeminy Fusion beats Comment:The degree of fusion varies with the P-VEB interval. With only a minor degree of ventricular contribution to fusion, the late-diastolic VEBs may pass unnoticed or be mistaken for effects o
Idioventricular Rhythm & AV Block
Report: Sinus rhythm 84/min Second degree AV block, Möbitz 1 (Wenckebach) Idioventricular rhythm 43/min AV dissociation Fusion beats (4th beat in the top strip, last in second strip) VEBs, small, possibly also fusion beats (bottom strip) Comment: D
Good Torsade, Wrong Components
Report: Sinus tachycardia 112/min Left bundle branch block Ventricular tachycardia 118/min Ventricular fusion beats Probable 1:1 retrograde conduction Junctional escape beats (bottom) Comment: The two panels are almost identical and one has to compa
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
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
