区域性左室功能失调是缺血性心脏病的一种标志,在急性心肌梗塞后数秒内,左室示节段性收缩异常,此现象亦发生于可逆性心肌缺血发作时。本文用二维切面超声图测定运动诱发心肌缺血时引起的左室功能失调。方法:28例患者均示有因心肌梗塞或心绞痛引起的胸痛,均属男性,平均年龄48岁(28～67岁)。在休息时、平卧作踏车运动时、及舌下含硝酸甘油后用30°角超声扫描仪探测心脏各部,超声头主要置于心尖、剑突下及胸骨左缘几个部位,探测心脏部位包括:(1)经心室底部处长轴;(2)经心尖处长轴;
Regional left ventricular dysfunction is a sign of ischemic heart disease, within seconds after acute myocardial infarction showed segmental segmental abnormalities of the left ventricle, this phenomenon also occurs in reversible myocardial ischemia attack. In this paper, two-dimensional incision ultrasound image was used to measure exercise-induced left ventricular dysfunction caused by myocardial ischemia. Methods: All 28 patients showed chest pain due to myocardial infarction or angina pectoris. All were male, with an average age of 48 years (28-67 years). At rest, supine for treadmill exercise, and sublingual nitroglycerin 30 ° angle ultrasound scanner to detect the heart of the Ministry, the ultrasound head is mainly placed in the apical, xiphoid and sternal left edge of several parts of the heart to detect The site includes: (1) the long axis at the base of the ventricles; (2) the long axis at the apex;
