目的探讨女性体表心电图ST-T改变的临床意义。方法对70例体检女性体表心电图ST-T改变者行心得安试验和冠状造影结果进行分析。结果70例女性中,56例年龄25～58岁,心得安试验阳性42例(75%)。14例年龄59～75岁,行冠状动脉造影,阳性4例(28%)。结论多数女性ST-T改变是植物神经功能紊乱所致,为功能性改变,女性临床依据体表心电图ST-T改变诊断冠心病要慎重。 Objective To investigate the clinical significance of ST-T changes in female body surface electrocardiogram. Methods 70 cases of physical examination female body surface electrocardiogram ST-T changes were tested and coronary angiography results were analyzed. Results Of the 70 women, 56 were aged 25-58 years old and 42 were tested positive for propranolol (75%). Fourteen patients aged 59-75 years underwent coronary angiography, 4 were positive (28%). Conclusion Most female ST-T changes are caused by dysfunction of autonomic nervous system. For functional changes, women should be cautious in diagnosing coronary heart disease based on ST-T changes of body surface electrocardiogram.
