Regular narrow QRS complex tachycardias are a common problem encountered by general internists or family practitioners. Although such tachycardias often occur in patients with a normal heart and seldom represent life-threatening conditions, they may cause bothersome symptoms. The key to approaching the diagnosis of these arrhythmias is identifying atrial activity (P waves) on the surface electrocardiogram and classifying the tachycardia as long RP or short RP. On the basis of that information, a differential diagnosis can be generated, logical therapy can be delivered for termination of the tachycardia, and a plan can be developed to prevent recurrence. Because intravenously administered adenosine alleviates 90% of the episodes of supraventricular tachycardias and has minimal side effects, it has become the drug of choice for termination of most types of narrow QRS complex tachycardias.
规则的窄QRS波群心动过速是普通内科医生或家庭医生常见的问题。虽然这类心动过速常发生于心脏正常的患者，且很少代表危及生命的情况，但它们可能会引起令人烦恼的症状。诊断这些心律失常的关键是在体表心电图上识别心房活动（P波），并将心动过速分类为长RP或短RP。基于这些信息，可以进行鉴别诊断，采取合理的治疗措施终止心动过速，并制定预防复发的计划。由于静脉注射腺苷可缓解90%的室上性心动过速发作，且副作用极小，它已成为终止大多数类型窄QRS波群心动过速的首选药物。
