本文7例冠脉痉挛均发生于冠心病。其中变异型心绞痛4例(2例分别于35天、60天转为 AMI)。胸痛发作时均有 ST 段抬高0.1～0.8mv,建议冠脉痉挛 ECG诊断标准为:①胸痛发作时 ST 段明显抬高,并在短时内恢复正常。②胸痛发作时ST 段明显抬高,虽在短时内未恢复正常,但 ST 段上升幅度随着心绞痛有较明显动态演变。③胸痛时 ST 段明显抬高伴其他导联缺血性下移,均在短时内恢复。④胸痛时伴暂时性 Q 波而无酶学改变者。
Seven cases of coronary spasm occurred in coronary heart disease. Including variant angina in 4 cases (2 cases in 35 days, 60 days converted to AMI). ST segment elevation during chest pain 0.1 ~ 0.8mv recommended coronary artery spasm ECG diagnostic criteria: ① ST segment was significantly elevated during chest pain and returned to normal within a short time. ST segment was significantly elevated during the onset of chest pain, although not returned to normal in a short time, but the ST segment increased with the angina more obvious dynamic evolution. ST segment was significantly elevated chest pain with other lead ischemic down, were recovered within a short time. ④ chest pain with temporary Q wave without enzymatic changes.
