本文比较运动后和经食道心房调搏中两维超声心动图(2-DE)检出冠心病的可行性和价值.78例受检者因胸痛而作冠状动脉造影,经剔除瓣膜性心脏病和心肌病,且静息时2-DE图象清晰.负荷试验前停用心脏活性药物72小时.卧位蹬车试验直到出现心绞痛、呼吸困难或疲劳为止.经鼻孔向食道内插入双极导管,逐渐加快心房调搏速率直到出现心绞痛或心率达得150次/分.运动停止后15～20秒和调搏中,患者取左侧卧位,记录相互正
This article compares the feasibility and value of two-dimensional echocardiography (2-DE) detection of coronary heart disease after exercise and transesophageal atrial pacing in 78 patients with coronary artery angiography due to chest pain, after valvular heart disease And cardiomyopathy, and 2-DE images were clear at rest. Cardiac active drug withdrawal 72 hours prior to loading test. , And gradually speed up the atrial pacing rate until angina pectoris or heart rate reached 150 beats / min. 15 to 20 seconds and pacing after the exercise stopped, the patient take the left lateral position, record each other
