本文用 CTS—16超声心动图对从我院1650名健康检查者中筛选出的37例老年前期及老年期陈旧性心肌梗塞患者作了左室室壁活动异常、左室收缩及舒张功能的微机分析。超声心动图所观察到的室壁活动异常与心电图的梗塞定位是一致的;此外超声心动图还可以观察到较心电图定位更为广泛的受累部位,如心尖部在各型心肌梗塞中均易受累。对于心电图异常而超声检查无异常的患者,可能与心脏功能恢复较好有关。Q 计数与超声结果相比显示 Q 计数越高,梗塞范围越大。与对照组相比,心肌梗塞患者的收缩及舒张功能不同程度受损。因此,使用超声心动图微机分析陈旧性心肌梗塞,精度高、速度快,对于确立诊断,判断梗塞范围以及估计患者预后等方面有一定的诊断价值。
In this paper, CTS-16 echocardiography from our hospital 1650 health screening in 37 cases of elderly patients with senile and elderly patients with myocardial infarction were left ventricular wall abnormalities, left ventricular systolic and diastolic function of the computer analysis. Echocardiography observed wall abnormalities and ECG infarction positioning is consistent; in addition to echocardiography can be observed more widely than the electrocardiographic location of the affected parts, such as the apex in all types of myocardial infarction are susceptible . Patients with abnormal ECG without abnormalities may be associated with better cardiac function. Q count compared with ultrasound results showed that the higher the Q count, the greater the infarct range. Contrast and control groups, myocardial infarction patients with varying degrees of impaired systolic and diastolic function. Therefore, the use of echocardiography computer analysis of old myocardial infarction, high precision, fast, for the establishment of diagnosis, determine the extent of infarction and prognosis of patients with certain diagnostic value.
