It's the ECG's that george rejects that makes George's ECG's the best.
Post-Ectopic SA Depression Mime of SA Wenckebach
Report:Sinus rhythm 87/min SVEBs, blocked First degree AV block Right bundle branch block Comment:Acceleration before pauses is the hallmark of SA Wenckebach exit block. This would be a good example if the pauses were not generated by premature b
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 intraven
Wrong Footprints
Report:Sinus rhythm Non-conducted SVEBs Trigeminy Left bundle branch block Comment:Surprising number of staff reported these strips as Wenckebach (Möbitz 1) second degree AV block. The reason may be the memory of Marriott's injunction to "recogn
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
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 “phenomenon”) Lower strip: Sinus rhythm SVEBs, probably of atrial origin RBBB aberrancy Couplet, second SVEB non-conducted Comment:Looking at the rabbit from behind, if the
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 0.26”) Right bundle branch block (QRS 0.14”) 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 the ‘
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 – probably of junctional origin – after the first, fi
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 0.14” (in basic RBBB morphology)
