Erythromycin Torsade de Pointes
Report:Sinus tachycardia 122/min Nonspecific T wave changes Prolonged QT interval Comment:This is one of those tracing where inspection is better than attempts at precise measurement and QTc calculation: there is a clear-cut long ST segment and the T w
Echo Beats
Report: Sinus rhythm (7 beats) Ventricular tachycardia (4-beat run) VEBs, couplet (two beats) Reentry (echo) beats of ventricular origin (two beats) Comment: There are more QRS complexes of ventricular than supraventricular origin here - 8 vs. 7. Both

Report: Sinus rhythm (7 beats) Ventricular tachycardia (4-beat run) VEBs, couplet (two beats) Reentry (echo) beats of ventricular origin (two beats) Comment: There are more QRS complexes of ventricular than supraventricular origin here - 8 vs. 7. Both
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
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,
Ventricular Tachycardia in a Patient with Permanent Pacemaker
Report: Ventricular tachycardia 154/min ?Retrograde VA conduction Comment: The QRS is a monophasic R wave in V1, just over 0.16â long: both the morphology and the QRS duration support the diagnosis of VT. The duration criterion is > 0.14â for V1 pos
Shifting Rabbit Ears in VT
Report: Ventricular tachycardia 152/min Possible old anterior infarction Comment: There is a monophasic R, possibly a qR, in V1, with northwest axis in the standard leads and QSs in V5-6. The patient in fact had an old anterior MI (Fig 106a below, in AF
