【摘要】 目的 探讨24h动态心电图(Holter)评价冠心病患者无痛性心肌缺血的价值。 方法 应用Holter监测200例冠心病患者心肌缺血发作阵次、每次缺血发作时间和ST段最大压低值,以及昼夜缺血次数。 结果 无痛性心肌缺血(SMI)130例,占65%;伴典型心绞痛12例,占6.0%;心肌缺血发作时,快频率依赖者126例,占63%。昼夜发作规律为6:00~12:00发生最高,检出970阵次,占58.3%。 结论 Holter对心肌缺血和心律失常种类、发作时间、数量与日常活动的关系、变化规律以及药物的疗效进行详细的观察,是监测心肌缺血和心律失常有效方法之一。【关键词】 冠心病;心肌缺血;心律失常;动态心电图
