摘要
为探讨R落P上与R落T上与室性心动过速的联系,对40例住院及心电图监护,明确诊断为室性心动过速,心电图资料完整,有发作起始及终止的记录的病例,进行了临床及心电图分析。发现R落P上诱发室性心动过速,较R落T上为多见,但R落T上诱发的室性心动过速,临床症状较严重,阿斯综合征及心室颤动发生率高于R落P上组。本文还讨论了过早指数(R-R′/QT)、易损期指数(前周期×基础QT/联律间距(R-R′))在室性心动过速诊断中的意义。
In order to demonstrate whether the“R on P”or the“R on T”phenomenon maybe responsible for the initiation of ventricular tachycardia,40 hospitalized patientswith ventricular tachycardia,on routine ECG or monitoring,were studied.Our datasuggested that the ventricular tachycardia initiated by the“R on P”was more frequentthan that by“R on T”,but the clinical manifestations of the latter cases appearedto be more severe than those of the former.The significance of prematurity index andvulnerability index in the diagnosis of ventrieular tachycardia was discussed.
