陈旧性心肌梗塞的超声心动图微机分析

Analysis on Ultrasonic Cardiogram of Obsolete Myocardial Infarction

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。

This paper deals with the microprocessor analysis on the abnormal action of left ventriculon-all and the function of being diastolic and systonic of left ventricule,with the help of CTS—16 typeultrasonic cardiohrams of screened 37 cases,patients with obsolete myocardial infarction in preagedor aged period,from 1650 examinees in our institute.From the ultrasonic cardiogram it is observedthat the abnormal action of ventriculowall is corresponding eith the located infraction in the electrocardiogram;Also the wider diseaased locations can be observed from the ultrasonic cardiogram thanfrom the electrocardiogram,for example,among all typed of the of the myocardial infarction,the tipof heart is diseased eaasily.Besides,for the patients with abnormal electrocardiagram no abnormalby ultra exam may be connected with better recovery of heart function.Compared with the results ofultra exam,the higher the Q count is,the wider the myocardial infarction will be.Again,comparredwith the sample group,the systolic and diastolic function for the myocardial infarction patients de-creases in a certain degree.Therefore analysing ib ultrasonic cardiogram of obsolete myocardial in-farction would get high orecusuib abd great speed to have a certain value in forming the diagnasisand the limit of infarction and the prediction for the patients.
