摘要 目的:参照超声心动图检查结果并结合冠状动脉造影(CAG)检查结果,评价心电图右胸导联对急性右心室心肌梗死(ARVI)早期诊断的应用价值。方法:入选ST抬高型下壁心肌梗死(STEIMI)108例经CAG及超声心动图检查确认为ARVI,分为ARVI组(38例)和单纯STEIMI组(62例),对比分析其心电图右胸导联改变情况。结果:指标以Ⅴ4~5 R导联或单独Ⅴ5 R导联ST段上移≥0.1 mV敏感性最高(100%),特异性为74.7%;特异性以Ⅴ5 R导联ST段上移≥0.05 mV最高(100%),而Ⅴ4~5 R导联ST段上移≥0.05 mV为90.3%。结论:ST抬高型下壁心肌梗死(STEIMI)患者需及早记录心电图右胸导联,建议一旦发现Ⅴ5 R导联ST段上移≥0.05 mV应及早明确急性右心室心肌梗死(ARVI)诊断并积极处理。
