We present an update on clinical and electrophysiological criteria used for the differential diagnosis of regular supraventricular tachycardias. Although several electrocardiographic clues may assist in the differential diagnosis, this is usually accomplished at electrophysiology study, and most often, the differential diagnosis is between atrioventricular nodal reentrant tachycardia, atrioventricular reentrant tachycardia due to a concealed accessory pathway, and atrial tachycardia. Atrial and ventricular pacing maneuvers during sinus rhythm or tachycardia have been used with various success rates. In clinical practice, these techniques cannot be applied to all cases, and multiple criteria must be used for the differential diagnosis of narrow-complex tachycardias with atypical characteristics.
我们对用于鉴别诊断规则性上性心动过速的临床和电生理标准进行了更新。尽管一些心电图线索可能有助于鉴别诊断，但这通常是在电生理研究中完成的，而且通常情况下，鉴别诊断是在房室结折返性心动过速、隐匿性旁路引起的房室折返性心动过速和房性心动过速之间进行的。在窦性节律或心动过速期间进行心房和心室起搏操作已被用于各种不同的成功率。在临床实践中，这些技术不能应用于所有病例，并且必须使用多种标准来鉴别诊断具有非典型特征的窄 QRS 心动过速。
