快速心房颤动时心电图示ST段压低42例临床分析

Clinical study of 42 patients with ST-segment depression during rapid atrial fibrillation

目的探讨快速心房颤动(房颤)时心电图示ST段压低对冠心病的诊断价值。方法选取阵发性快速房颤患者42例,行活动平板运动试验及冠状动脉造影检查。结果 42例患者行活动平板运动试验阳性28例,占全部患者的66.7%;冠状动脉造影阳性20例,占全部患者的47.6%。结论快速房颤时心电图ST段压低作为冠心病的诊断标准无特异性,此类患者应考虑行活动平板运动试验及冠状动脉造影检查,以便早期发现和治疗。

Objective To explore the significance of ST-segment depression during rapid atrial fibrillation in the diagnosis of coronary heart disease. Methods Forty-two patients with ST-segment depression during rapid atrial fibrillation, who need to undergo treadmill exercise testing and coronary angiography, were enrolled. Results Of the 43 patients, 28 （66.7%） were positive in treadmill exercise and 20 （47.6%） were positive in coronary angiography. Conclusion ST-segment depression during rapid atrial fibrillation is not predictive for the presence of coronary heart disease. Treadmill exercise testing and coronary angiography are necessary for patients with ST-segment depression during rapid atrial fibrillation for early diagnose and treatment of coronary heart disease.
