恶性快速性室性心律失常的发作方式及其临床意义

探讨恶性快速性室性心律失常的发作方式及其临床意义,分析64例在入院后至少发生≥1次由室性早搏(简称室早)诱发的恶性快速性室性心律失常患者发作时与发作前后的常规12导联心电图或持续心电监护心电图。结果:根据诱发恶性快速性室性心律失常的室早的联律间期及其前间歇的长短,64例的发作方式大致可分为以下几种类型:①单纯室早诱发;②长间歇依赖性室早诱发,此型根据基础心律QT(U)间期的长短又可分为:a.QT间期正常;b.长QT(U)间期两种形式。不同发作方式之干预措施亦异。结论:恶性快速性室性心律失常是由不同形式的室早所诱发的,他们具有不同的临床、心电学特征及干预措施。

Mode of Onset and Clinical Significance of Malignant Rapid Ventricular Arrhythmia

To explore mode of onset and clinical significance of malignant rapid ventricular arrhythmia, the conventional 12 leads electrocardiogram or sustained electrocardiomonitor graph were analysed in 64 patients, they had malignant rapid ventricular arrhythmia caused by ventricular extrasystole once or more after who were admited to hospital. Results: According to long or short of coupling interval of the ventricular extrasystole and the interval in front of it ,The mode of onsent of the malignant rapid ventricular arrhythmia were individed into the following types: ①caused by the ventricular extrasystole with normal QT interval;②caused by the ventricular extrasystole of dependent on long interval ,and they were again individed into two types accordiog to QT interval of basic heart rhythm: with normal and long QT interval. The different mode of onset had different interventional measures. Conclusion:The malignant rapid ventricular arrhythmia bring out ventricular extrasystole of the different pattern, which have different clinical and electrocardiographic characteristics and interventional measures.
