Negative Concordant Precordial Pattern in VT
Report: Ventricular tachycardia 170/min Comment: All the chest leads show negative QRS complexes. In VT, this used to be one of the criteria distinguishing it from aberrantly conducted SVT; now only positive concordance is still held valid as a VT criter
Complete AV Block in Shock
Report:Atrial flutter 375/min Complete (3rd degree) AV block Junctional rhythm 65/min Right axis deviation +90o ?LPHB Right bundle branch block Acute inferior and anteroseptal infarction Leads V3-6 probably right-sided: right ventricular infarction
Möbitz I & II Combined: Arrhythmia Simulator
Report:Sinus rhythm. Möbitz 1 [Wenckebach] second degree AV block, with 3:2 and 4:3 periods [top strip]. Möbitz 2 second degree AV block, with 3:2 and 4:3 periods. Complete RBBB coincident with Möbitz II block. Complete AV block [bottom strip]. Co
Iatrogenic Ventricular Standstill
Report: Sinus rhythm 100/min Ventricular standstill (asystole) Comment: Hereby hangs a tale: The ECG technician ran to my (reporting) room in New York pale and trembling, clutching this trace in obvious fear. A senior Cardiologist saw her taking the ro
Monomorphic Ventricular Tachycardia
Report:Ventricular tachycardia 150/min Comment:In lead V1 the QRS is a monophasic R wave with left rabbit ear taller than the right, with duration just over 0.14â. These features, along with bizarre frontal plane axis, are sufficient to diagnose ventri
Large Rabbit Ears and Prominent A-V Dissociation with Positive Concordant Precordial Pattern
Report: Sinus rhythm 82/min Ventricular tachycardia 158/min Complete A-V dissociation Left atrial abnormality (LAA) Comment:This title contains three major features of ectopic ventricular tachycardia and is well suited to teaching beginners in electro
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:
Ventricular Tachycardia : Useless Rabbit Ears
Report: Ventricular tachycardia 152/min Comment: The diagnosis is based on the monophasic R waves in V1 and the bizarre, indeterminate, no-manâs land or north-west axis; it is supported by the QRS duration of 0.18â. It is further strengthened by the
Multiform & Monomorphic Ventricular Tachycardia
Report: Multiform ventricular tachycardia 180-210/min Comment: The tachycardia becomes (or looks) uniform in some leads, as is often the case in both torsades de pointes and other types of multiform ventricular tachycardia. It starts with what Marriott a
Onset of Multiform VT
Report: Sinus tachycardia 110/min Intraventricular conduction delay, probably RBBB VEBs, possibly fusion beats Small voltage in frontal leads Multiform ventricular tachycardia 160 â 290/min Comment: First, third and sixth beats may be fusion beats,
