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
Slurred R Ascent in V1: Exception to the Rule
Report:Ventricular tachycardia 168/min Comment:The contour of V1 suggests a rabbit in profile, with overlapping ears â not very helpful. If one, more properly, imagines looking at the rabbit from behind, there is a suggestion of larger right ear â no
Accelerated Idioventricular Rhythm (AIVR)
Report: Accelerated idioventricular rhythm (AIVR) 88/min Comment: The RRâ complexes with taller left rabbit ear in V1, the bizarre (indeterminate, northwest, nonsense) axis and the QRS duration of > 0.16â establish the ectopic ventricular origin of t
Alternate Cycle Antecedent P Waves
Report:Ventricular tachycardia 125/min Probable 2:1 retrograde conduction Comment:The diagnosis of VT is supported by the QRS duration of 0.18â, the indeterminate abnormal axis and the left rabbit ear in V1 being taller than the right. The relativel
Northwest Axis of Ventricular Tachycardia
Report: Ventricular tachycardia 167/min Comment: The diagnosis of VT rests on monophasic R wave in V1, rS in V6 and the bizarre, âNorthwestâ axis in the limb leads. In V1 there is a soupçon of rabbit ears, with the left one taller than the right. I
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 0.14â (in basic RBBB morpholog
Ventricular Tachycardia: Pseudo P Waves at Either Complex End
Report:Sinus rhythm 84/min. Ventricular tachycardia 132/min. Complete AV dissociation. Comment:The broad-complex tachycardia has QRS duration 0.20", extreme "Northwest" axis and, best of all, taller left rabbit ear in V1 to declare its ventricular orig
Monomorphic Ventricular Tachycardia: Minuscule V1 Rabbit Ears
Report:Monomorphic ventricular tachycardia 188/min Comment:The monophasic R complex in V1 has two small ârabbit earsâ; the left one is mostly taller than the right (looking at the rabbit from behind). This is a classic marker of ventricular ectopic o
