It's the ECG's that george rejects that makes George's ECG's the best.
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
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:
Pædiatric SVT
Report: Orthodromic atrioventricular re-entrant tachycardia 333/min Possible flutter with 1:1 conduction Left bundle branch block ?Wolff-Parkinson-White syndrome ( see below) Comment: The rate is very fast, but an infant’s flutter can be much faster s
Positively Concordant Trigeminy
Report: Sinus tachycardia 130/min VEBs in trigeminy Left atrial abnormality Minor T wave changes Comment: The VEBs are monophasic R complexes from V1 through V6. This is diagnostic of ventricular ectopic origin. A regular run of such beats, however, w
Two Wrongs Making Two Rights!
Report: Sinus tachycardia 110/min Left bundle branch block Left axis deviation Runs of ventricular tachycardia 150 - 160/min AV dissociation Ventricular fusion beats Comment: This is from Schamroth himself: two wrongs sometimes make a right60. The t
SVT with LBBB
Report: Supraventricular tachycardia 152/min Left bundle branch block Comment: The rS complexes in lead V1 are perfectly ‘normal’ LBBB complexes in that the initial R wave is narrow, the S downstroke is sharp and the upstroke slurred. The frontal plane
Atrial Tachycardia with LBBB Aberrancy
Report: Sinus rhythm SVEB (first beat) 4-beat run of atrial tachycardia Left bundle branch block aberrancy Comment: The first beat of the tachycardia is normally conducted, the other three are conducted with LBBB. While the initiating beat is atrial
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 intraventr
LBBB: Old Myocardial Infarction
Report:Sinus rhythm 64/min Third degree AV block Junctional escape rhythm 36/min Left bundle branch block QRS 0.22” Probable old anterior infarction Comment:The patient had LBBB since his original infarction; the present morphology is identical to
Incongruous BBBB
Report: Sinus rhythm 84 – 88/min Advanced second degree AV block 3:1 & 4:1 AV block Right bundle branch block PR interval 0.32” Left bundle branch block PR interval 0.20” Comment: This is quite rare. The two bundle branch blocks have different but
