Rate-Dependent LBBB
Report: Sinus rhythm 90/min SVEBs, blocked, in bigeminy Left bundle branch block, rate-dependent Comment: The blocked atrial extrasystoles are discretely etched on the onset of the T wave. In the upper strip, the last LBBB complex has a distinctive nip
Xylocaine Reflex
Report: Top & middle: Atrial fibrillation Rate-dependent left bundle branch block VEB Bottom: Sinus rhythm SVEBs with LBBB aberration Comment: This is a fine example of xylocaine reflex, compounded by two 200 Joule shocks! There was no need for it:
Rabbit Ears For and Against
Report:Upper strip: Sinus tachycardia 104/min VEBs, late-diastolic (R-on-P âphenomenonâ) Lower strip: Sinus rhythm SVEBs, probably of atrial origin RBBB aberrancy Couplet, second SVEB non-conducted Comment:Looking at the rabbit from behind, if
Short Compensatory Pauses?
Report:Sinus rhythm. VEBs, some in pairs (couplets). SVEBs, couplet, following the last VEB couplet. Comment:The single VEB in the middle of the strip appears to have the usual, fully compensatory pause, being contained in a space of two sinus cycles.
Rule of Bigeminy: VEBs & SVEBs
Report: Sinus rhythm First degree AV block (PR 0.26â) Right bundle branch block (QRS 0.14â) VEBs SVEBs, junctional Comment: All four SVEBs follow, after one cycle, the VEBs and the last VEB in the bottom strip follows a SVEB, perhaps reflecting t
Mixed Bigeminy
Report: Sinus rhythm 74/min SVEBs, blocked VEBs Left ventricular hypertrophy with ST/T changes Comment: The diagnosis of sinus bradycardia is refuted by the negative (in the inferior leads) P waves â probably of junctional origin â after the first
Ventricular Tachycardia Rightly (Mis)diagnosed
Report:Ventricular tachycardia 170/min Comment:There is nothing against the diagnosis of VT in this trace, and a lot in its favour: monophasic R waves in V1 with left rabbit ear taller than the right and QRS duration over 0.14â (in basic RBBB morpholog
