Polymorphic ventricular tachyarrhythmias are highly lethal arrhythmias. Several types of polymorphic ventricular tachycardia have similar electrocardiographic characteristics but have different modes of therapy. In fact, medications considered the treatment of choice for one form of polymorphic ventricular tachycardia, are contraindicated for the other. Yet confusion about terminology, and thus diagnosis and therapy, continues. We present an in-depth review of the different forms of polymorphic ventricular tachycardia and propose a practical step-by-step approach for distinguishing these malignant arrhythmias.
多形性室性心动过速是高度致命性的心律失常。几种类型的多形性室性心动过速具有相似的心电图特征，但治疗方式不同。事实上，被认为是一种多形性室性心动过速首选治疗药物的药物，对另一种则是禁忌。然而，术语混淆，以及由此导致的诊断和治疗仍然存在。我们对不同形式的多形性室性心动过速进行了深入的回顾，并提出了一种实用的逐步方法来区分这些恶性心律失常。
