Abstract: 目的:探讨西宁地区藏族急性心肌梗死(急性心梗)患者碎裂QRS波与近期预后的关系.方法:对143例确诊为“急性心梗”的藏族患者,根据是否出现碎裂QRS波分为两组,分别统计其发生近期死亡事件(RDI)、室性心律失常事件(VAI)、B型钠尿肽(BNP)、左室射血分数(LVEF)及左室舒张末期内径(LVDD)值,比较两组间差异.结果:碎裂QRS波发生率21.7%.两组间VAI、RDI、BNP、LVEF有显著差异;两组间LVDD无显著差异.结论:西宁地区藏族急性心梗患者碎裂QRS波发生率较低;常规12导联心电图上存在碎裂QRS波是急性心梗患者近期死亡和室性心律失常事件、左心功能受损的强有力指标.
