摘要
本文报告应用动态心电图监测42例 Lown Ⅳ级 A、B 型室性心律失常并对其进行3～50月(21.9±19.75月)随访。结果表明,21例短阵室速中有6例死亡,5例为心性猝死;21例成对室早有3例猝死。在8例猝死中,有6例呈缺血性 ST 段改变,提前指数≤1者5例。基础病变分别为陈旧性心梗4例,心肌病2例,风心病1例,冠心病心衰1例。伴有心衰者共4例。认为短阵室速和成对室早的预后与其基本心脏病的严重程度、心功能状态、心肌缺血和提前指数≤1等因素有关。
Forty—two patients with nonsustained ventricular tachycardia(≥triplets)and ventricular couplets were identified retrospectively from a population of 720 consecutive patients referred for 24 hour ambulatory electrocardiography monitoring and studied to determine the prog- nostic significance.Eight of these 42 patients suffered from sudden cardiac death during a mean follow—up of 21.9+19.75 months,suggesting that prognostic significance of Patients with nonsustained ventriculer tachycardia and ventriculer couplets were associated with un- derlying cardiac diseases,cardiac function,cardiac isehemia and prematurity index(RR'/QT) of the initiating beat(≤1).Thus,Patients with old myocarcial infarction or dilated cardiomy- opathy and congestive heart failure accompanying nonsustained paroxysmal ventricular tachycardia and ventricular couplets are a high risk for sudden death and are ideal candidates for prophylactic interventions.
