心机械图应用於临床在测定左心功能方面,近期在国内外篷勃开展、它是目前非侵入性诊断方法中可靠性较高的一种。其中左心室收缩时间间期STI)的测定被认为是简单而可靠的方法,对评价病情转归与药物疗效等有重要价值。本组60例中LVET,PEP,△一LVET,LYETI,PEPI,均有显著性差异及非常显著性差异(P值0.05,0.01),在评价左心功能时无以P/L值为重要依据,我们认为P/L值>0.43以上为不正常。其次根据不同心尖搏动图一起综合判断。因为在冠心病时心肌柔顺性改变,收缩力减退,收缩不协调,因而产生了收缩波形的改变。其中尤对心肌梗塞患者病情演变,转归及预后为一良好的观察指标。虽然心机械图能较正确地反映左心舒张期动态及左心射血功能。但仍存在有对疾病的检出和鉴别的特异性不显著,因此须综合病史,及其它资料,全面分析做出结论。
Cardiac mechanical map used in clinical determination of left ventricular function, the recent booming at home and abroad, it is currently a non-invasive diagnostic method of a higher reliability. Which the left ventricular systolic time interval STI) determination is considered as a simple and reliable method for the evaluation of the outcome of the disease and the efficacy of drugs of great value. The group of 60 cases LVET, PEP, △ a LVET, LYETI, PEPI, there was a significant difference and a very significant difference (P value 0.05,0.01), in the evaluation of left ventricular function without P / L value as an important basis , We think that P / L value> 0.43 is not normal. Second, according to different apical pulsation diagram with comprehensive judgment. Because in the coronary heart disease when the flexibility of the myocardium changes, contractility decreased, contractions are not coordinated, resulting in a contraction of the waveform changes. Especially in patients with myocardial infarction evolution, prognosis and prognosis as a good indicator. Although cardiac mechanical map can more accurately reflect the left ventricular diastolic dynamic and left ventricular ejection function. However, the specificity of the detection and identification of the disease remains insignificant. Therefore, we must make a comprehensive analysis based on the medical history and other data.
