The index of suspicion for accessory atrioventricular conduction pathways must be high in patients with paroxysmal tachycardias in order to avoid overlooking subtle delta waves or short PR intervals. The existence of many different types of accessory AV conduction syndromes can make therapy difficult. Understanding the physiology of each patient's tachycardia can make successful management more rapid, and empiric therapy should not be pursued indefinitely if early drug regimens are unsuccessful. Electrophysiologic study may elucidate the mechanism of the tachycardia and simplify the selection of an ideal drug regimen.
对于阵发性心动过速患者，必须高度怀疑存在房室旁道，以免忽略细微的δ波或短PR间期。多种不同类型的房室旁道传导综合征的存在会使治疗变得困难。了解每位患者心动过速的生理机制可使成功治疗更加迅速，如果早期药物治疗方案不成功，不应无限期地采用经验性治疗。电生理研究可阐明心动过速的机制，并简化理想药物治疗方案的选择。
