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 investigate the relationship between R-P and R-T and ventricular tachycardia, 40 cases of inpatient and ECG monitoring, definite diagnosis of ventricular tachycardia, complete electrocardiogram data, and records of onset and termination of seizures Case, a clinical and ECG analysis. Found that R fall P on the induced ventricular tachycardia, compared with R fall T is more common, but R fall T induced ventricular tachycardia, more serious clinical symptoms, Asperger’s syndrome and higher incidence of ventricular fibrillation R falls on the P group. The paper also discusses the significance of premature exponential (R-R ’/ QT), vulnerability index (pre-cycle × basal QT / R-R’) in the diagnosis of ventricular tachycardia.
