本文评价了核听诊器测定心功能指标的临床应用价值与限制。对18名正常人及40例心肌梗塞、14例心绞痛、7例充血型心肌病、3例风湿性心脏病患者的研究结果表明:凡主要累及心肌收缩功能的心脏病,用该法测得的心功能指标,有助于判断患者有无心功能不全及对心功能不全的程度进行半定量分析。观察运动前后心功能指标的改变趋势,可了解患者的心脏储备能力。但累及瓣膜的风湿性心脏病,由于心室内容积产生异常的增加或减少,故用该法测得的容积指标的可靠性降低。为克服病人及测定两方面的干扰因素,应合理掌握适应证,操作标准化,可进一步提高临床应用价值。
This article evaluates the clinical value and limitations of nuclear stethoscope in the determination of cardiac function. 18 normal subjects and 40 cases of myocardial infarction, 14 cases of angina pectoris, 7 cases of congestive cardiomyopathy, 3 cases of rheumatic heart disease in patients with the results showed that: the main involvement of myocardial systolic heart disease, measured by the method Cardiac function indicators help to determine whether patients with or without cardiac insufficiency and semi-quantitative analysis of the extent of cardiac insufficiency. Before and after exercise to observe the changing trend of cardiac function indicators, patients can understand the heart’s reserve capacity. However, rheumatic heart disease involving the valve, due to abnormal increase or decrease of the ventricular volume, the reliability of the volumetric index measured by this method is reduced. To overcome the interference of patients and determination of two factors, should be a reasonable grasp of indications, standardization of operations, can further enhance the clinical value.
