观察对象为冠心病68例,均系男性,年龄40～68(平均52.9)岁,诊断符合世界卫生组织拟订的标准。正常人40例,均为男性,年龄40岁以上,平均47.1岁,均经详细询问病史、体验、胸部X线、常规心电图及运动试验、超声心动图、血脂等检查,确定无心血管病、肺部疾病及内分泌、代谢性疾病、结缔组织疾病和可能影响心功能的因素。采用Manolas氏提出的心尖搏动图各振幅及振幅指数a/H、a/D、TARTi、DATi等为指标,通过食管心房调搏负荷观察受检查者的舒张功能改变。调搏心率以160次/分为终止点。结果见表1,2。
The observation object was coronary heart disease in 68 cases, all male, aged 40-68 (mean 52.9) years old, the diagnosis was in line with the standard set by the World Health Organization. Normal 40 cases, all men, aged 40 years of age, average 47.1 years old, were asked in detail about history, experience, chest X-ray, ECG and exercise tests, echocardiography, blood lipids and other tests to determine no cardiovascular disease, lung Department of disease and endocrine, metabolic diseases, connective tissue diseases and may affect cardiac function. The amplitude and amplitude index a / H, a / D, TARTi, DATi and other indexes of apex beat pulsation proposed by Manolas were used as indexes to observe the change of diastolic function of the subjects through esophageal atrial pacing load. Pacing heart rate to 160 times / points for the termination. The results are shown in Tables 1 and 2.
