Objective To quantitatively evaluate the recovery extent of left ventricular damage in acute coronary syndromes ( ACS ) after percutaneous coronary intervention ( PCI ) by ST-segment changes ( elevation and depression ) combining echocardiography ( ECHO ) .

目的应用ST段改变（抬高和 压低）联合超声心动图（ECHO）评价经皮冠状动脉介入（PCI）术后急性冠脉综合征（ACS）患者左 心室损害恢复程度。

To Acute Left Ventricular Failure as the First Performance of the Universal-type ST-segment Depression Myocardial Infarction Clinical Analysis of 20 Cases

以急性左 心衰竭为首发表现的普遍ST段 压低型心肌梗死20例临床分析

Results The heart rate of 90.55 % of the patients increased during the procedure which included sinus tachycardia ventricular premature beat or atrial premature beat . The main changes of ST-T segment were T wave flattening or inversion or ST segment depression .

结果胃镜术中90.55%的病人出现心率增快，出现的心律失常以窦性心动过速、 室 性期前收缩及房性期前收缩多见，STT改变以T波低平及ST段 压低 为主。

Heart failure ( CHF ) is due to ventricular dysfunction caused by a clinical syndrome characterized by cardiac output showed a decline in ventricular filling pressure increases can cause respiratory depression fatigue and edema .

心力衰竭（简称心衰）是由于心室功能不全引起的一种临床综合征，其特点表现为心输出量减少， 心室充填压增加，可产生呼吸 困难、疲劳及水肿等 症状。
