Historias eléctricas singulares: Taquicardia ventricular bidireccional y otros eventos

Bidirectional ventricular tachycardia is a rarely seen arrhythmia; resulting from a triggered activity alternatively originated in the left anterior and posterior fascicles with a beat-to-beat rightward alternation of the frontal plane axis, thus causing bidirectional appearance. Two patients with this atypical arrhythmia along with their electrocardiographic tracings are presented in this article.
