经动态心电图确诊的短阵室速56例中早搏型短阵室速频率较快,面并行型与定性自主节律增高型较慢;经测定绝大部分短阵室速的提前指数>1,而易损指数<1.4.因此,一般不会引起室颤.56例经1--3年随访,短阵速室绝大部分自行消失,未见引起阿-斯综合征发作或死亡。 The fast ventricular tachycardia diagnosed by ambulatory electrocardiogram in 56 cases of premature beat-type short-staged ventricular tachycardia frequency faster, facial parallel type and qualitative autonomic rhythm increased slower; the majority of measured ventricular tachycardia antecedent index> 1, and Vulnerability index <1.4, therefore, generally does not cause ventricular fibrillation .56 cases after 1 - 3 years of follow-up, most of the short-speed room disappear on their own, no cause of Asin’s syndrome or death.
