Bidirectional Ventricular Tachycardia
Report: Bidirectional ventricular tachycardia Probable digoxin toxicity Supraventricular rhythm of uncertain origin ? atrial fibrillation VEB Multiform ventricular tachycardia Comment: Despite the adverse prognosis and her age, she was discharged hom
Alternating Ventricular Tachycardia
Report: Ventricular tachycardia 136/min Alternating QRS morphology throughout Comment: This is a good example of how alternating and bidirectional tachycardia are basically the same. This one would be called bidirectional if only the negative axis in
Slow Bidirectional Tachycardia
Report: Bidirectional tachycardia 104/min Retrograde VA conduction Junctional escape beats AV dissociation Sinus rhythm 95 â 98/min Overdrive (post-ectopic) SA suppression Comment: The rhythm is obviously bigeminal, with narrow rSRâ complexes
Bidirectional AIVR
Report: Alternating (bidirectional in some leads) accelerated idioventricular rhythm Comment: At first glance, the trace suggests RBBB and ventricular bigeminy. It is quite regular and no definite atrial activity can be discerned, except for the wrinkle
