Keyword:  晕厥心律失常心电描记术;
Abstract: 目的:探讨动态心电图在晕厥病因诊断中的应用价值.方法:对56例疑为严重心律失常所致的1次或多次晕厥的患者观察24 h动态心电图.嘱其尽量以诱因促使晕厥发作,并记录发作时间.结果:(1)56例经动态心电图均检出有严重心律失常,13例(23%)晕厥发作与心律失常有关,其中尤其是与缓慢心律失常关系密切.心源性晕厥的发生系停搏或心动过速时间过长,有效心搏出量减少致脑部供血不足所致.(2)能够引起心源性晕厥的心律失常多见于40岁以上的患者,并随着年龄的增加而增多.结论:动态心电图检查可为心源性晕厥患者获得可靠的病因诊断.临床对发作性晕厥患者,尤其是中老年患者有必要进行动态心电图检查以明确病因,并给予及时治疗.
