It's the ECG's that george rejects that makes George's ECG's the best.
Sino-Atrial Wenckebach
Report: Sinus rhythm Left atrial abnormality (LAA) 5:4 and 4:3 sino-atrial exit block, Möbitz 1 Normal QRS/T Comment: In each pause, an entire P-QRS-T sequence is missing; the pause itself is less long than two sinus cycles. There is slight accelera
A Unique LBBB Aberrancy
Report: Probable supraventricular tachycardia 182/min Right axis deviation +110o LBBB Comment: The QRS complexes in V1-2 take almost 0.08” to reach the nadir of their S waves, but this is not immediately obvious on inspection. The initial QRS in V1 is
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
SVT: Pre-existing RBBB/LAHB
Report: Tachycardia 102/min ? origin Onset of supraventricular tachycardia 190/min Right bundle branch block Left anterior hemiblock Anterior infarction, probably old Comment: Frontal plane axis of –90o and the monophasic R wave in V1 bode ill for th
SVT with Right Bundle Branch Block Aberrancy
Report:SVT 212/min. Right bundle branch block (RBBB). Right axis deviation +120o probably left posterior hemiblock (LPHB). Comment:The likelihood of aberrancy rests with the rSR’ morphology in lead V1 and the absence of any bizarre features. Verapamil
Runs of Aberrant SVT
Report: Sinus rhythm Incomplete right bundle branch block SVEBs, some in couplets, of atrial origin SVEBs, single, of junctional origin, dissociated Short runs of atrial tachycardia Aberrant conduction, RBBB type, variable Comment: The QR morphology
SVT or VT?
Report: Broad-complex tachycardia 154/min Comment: The tachycardia has unusual RAD, possibly a qR morphology in V1 and virtually concordant positive precordial pattern; yet it resembles RBBB and there appears to exist a 1:1 atrial activity (best seen as
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)
SVT with Pre-Existing Left Bundle Branch Block
Report:Supraventricular tachycardia 200/min[! XE "Supraventricular tachycardia:LBBB:QRS0.16\"" !] Northwest axis +230o Small voltage in frontal leads Left bundle branch block Comment:This is a difficult trace to diagnose with certainty: the main featu
SVT or Verapamil-Responsive VT?
Report:SVT or VT 156/min. Right bundle branch block. Left anterior hemiblock. Comment:The tachycardia has a typical RBBB/LAHB morphology consistent with aberrantly conducted SVT. The rate varies slightly; this has no diagnostic significance. The probl
