本文对45例冠状动脉造影正常而有胸痛患者的左室造影进行详细研究,观察有无室壁运动异常。方法:45例左室压力、容量和冠状动脉造影均正常的患者,按记分法评定是否心绞痛。体征注意第三、四心音和二尖瓣返流的收缩期杂音,以及心电图变化。左室造影用电子计算机系统逐帧数字化,得出,(1)舒张末期容量和喷血分数。(2)重叠的心腔轮廓图,以观察有无室壁运动减少区域和有无
In this paper, 45 cases of coronary angiography with chest pain in patients with left ventricular angiography in detail to observe whether there is abnormal wall motion. Methods: 45 patients with left ventricular pressure, volume and coronary angiography were normal, according to scoring method to determine whether angina pectoris. Signs of attention to the third and fourth heart sounds and systolic murmur of mitral regurgitation, and ECG changes. Left ventricular angiography was digitized on a frame-by-frame basis using computerized computer systems and concluded that (1) end-diastolic volume and spurt score. (2) Overlapping cardiac chamber profiles to see if there is room reduction and presence or absence of wall motion
