心机械图测定舒张功能(DTI)和收缩功能(STI),是心脏病学非侵入性检查技术之一,可间接反映左心功能,对某些心脏病特别是冠心病的诊断及预后判断有一定价值,又可作为评定药物及手术疗效的指标,对心脏杂音及附加音的鉴别亦有帮助,因此,常用来评定左心功能。传统的测定方法是借助昂贵的多道生理记录仪,既费时又不便于推广,用微型计算机记录和处理势在必行。本文报道用西安深秦电子公司生产的
Cardiac mechanical measurements of diastolic function (DTI) and systolic function (STI), is a cardiological noninvasive examination of technology, can indirectly reflect left ventricular function, for some heart disease, especially coronary heart disease diagnosis and prognosis are A certain value, but also as a measure of the efficacy of drugs and surgical indicators of heart murmur and additional sound identification is also helpful, therefore, commonly used to assess left ventricular function. The traditional method of determination is to use expensive multi-channel physiological recorder, both time-consuming and not easy to promote the use of micro-computer recording and processing is imperative.
