The value and limitations of phonocardiography, systolic time intervals, apex cardiography and kinetocardiography in the diagnosis of impaired cardiac function during rest and haemodynamic stress were critically reviewed on the basis of studies carried out in our laboratory, as well as reports in the literature. When compared with invasively-obtained measurements, none of the above-mentioned techniques allows the prediction of heart function quantitatively in a single given patient. However, when one considers the broad overlap of mechanocardiographic measurements in normal subjects and patients with heart disease and defines an abnormal mechanocardiogram accordingly, these methods may be used to diagnose abnormal cardiac function with adequate specificity though low sensitivity.
基于我们实验室开展的研究以及文献报道，对心音图、收缩期时间间期、心尖搏动图和心动动力学图在静息和血流动力学应激期间心脏功能受损诊断中的价值和局限性进行了批判性综述。与通过侵入性获得的测量结果相比，上述技术均无法在单个特定患者中定量预测心脏功能。然而，当考虑正常受试者和心脏病患者的心机械图测量存在广泛重叠并据此定义异常心机械图时，这些方法可用于以足够的特异性（尽管敏感性较低）诊断心脏功能异常。
