患者女,37岁。因体检发现Ⅱ、Ⅲ、aVF导联ST段压低0.10mV,心率75次/min,自诉无上感和其他不适。20d后复查平静心电图表现同前。10d后再做心得安试验,一次性口服心得安20mg,1h后心电图表现:心率56次/min,电轴不偏,频发室性早搏,偶发室上性早搏,ST段恢复正常。嘱爬楼梯3min后心电图表现:心率66次/min,电轴不偏,频发室性早搏,偶发室上性早搏,ST段正常。2h后心电图表现:心率68次/min,电轴不偏,频发室性早搏(部分呈联律和间位性出现),偶发室上性早搏,ST段仍然正常。4.5h后心电图表现:心率70次/min,电轴不偏,偶发室性早搏,ST段改善不明显。上述过程中患者未感不适。
Female patient, 37 years old. Due to physical examination found that Ⅱ, Ⅲ, aVF lead ST segment depression 0.10mV, heart rate 75 beats / min, prosecution supreme sense and other discomfort. 20d after the review of calm electrocardiogram with the former performance. 10d and then do experience trial, a one-time oral propranolol 20mg, 1h after ECG: heart rate 56 beats / min, the electric axis is not partial, frequent premature ventricular contractions, premature supraventricular premature beats, ST segment returned to normal. Instruct the staircase after 3min electrocardiogram performance: heart rate 66 beats / min, the electric axis is not partial, frequent premature ventricular contractions, premature supraventricular premature beats, ST segment normal. 2h after ECG performance: heart rate 68 beats / min, the electric axis is not partial, frequent premature ventricular contractions (some were law and metaplasia), premature supraventricular premature beats, ST segment is still normal. 4.5h after ECG performance: heart rate 70 beats / min, the electric axis is not partial, premature ventricular premature beats, ST-segment improvement is not obvious. The patient does not feel discomfort during the above process.
