临床医学考虑运动后心电图(ECG)表现ST段下降是心肌缺血的阳性反应。妇女一生中由于性激素变化使其ECG的改变很明显,孕酮含量及雌、孕激素比例变化使青年妇女对运动试验起阳性反应,妇女绝经后服雌激素替代治疗时也有异常的ST段表现。妊娠期雌激素水平高,其血容量和心输血量增加,但妊娠期对运动的ECG反应至今尚无报告。作者的此项研究旨在证明妇女孕期和非孕期对运动的ECG改变。
Clinical Considerations Post-exercise ECG (electrocardiogram) performance ST-segment depression is a positive response to myocardial ischemia. Changes in women’s life because of sex hormones to ECG changes obvious, progesterone content and changes in the ratio of estrogen and progesterone so that young women from the exercise test positive reaction, women’s postmenopausal estrogen replacement therapy also have abnormal ST segment performance. Estrogen levels during pregnancy are high, and their blood volume and blood transfusions are increased. However, no ECG response to exercise during pregnancy has been reported. The authors’ study was designed to demonstrate changes in ECG in women during pregnancy and non-pregnancy.
