摘要 目的分析心肌梗死后胸导联ST段持续抬高与左心室室壁瘤、左心室射血分数的关系。方法对52例陈旧性心肌梗死伴ST段抬高者行左心室造影,比较各ST段抬高组的差别V1~V3、V1~V4(∑ST〈8mm及I〉8mm,∑ST:每例患者ST段抬高的毫米总数),V1~V5±V6导联组。结果V1~V4 ST段抬高〈8mm组有3(3/12)例室壁瘤,而≥8mm组有12(12/16)例,二者比较差异有显著性(P〈0.05),V1~V5±V6组14例均有室壁瘤。卵段抬高总毫米数与左室射血分数(LVEF)呈显著负相关(r=-0.65397,P〈0.001),各组的LVEF比较差异有显著性(F=12.99,P〈0.01)。结论ST段抬高在V1~V4以上,∑ST〉8mm,对诊断室壁瘤的价值较大,ST段抬高的程度可作为左心室收缩功能降低的判断指标。
