1. A method of rapid noninvasive measurement of parameters of diastolic function of left ventricle and automated evaluation of the measured profile of left ventricular function at rest and with exercise, wherein: the patient performs an isometric exercise through an external device, an external pressure transducer and heart sounds microphone are applied as noninvasive sensor units on the thoracic wall to obtain a noninvasive left ventricular pressure mirroring curve (pressocardiogram) and simultaneously the heart sounds (phonocardiogram); and and an external utilization unit determines and calculates characteristic diastolic parameters derived from the pressocardiographic curve and phonocardiogram at rest, during and after exercise, converts each said pressocardiogram into a digital waveform in the time domain, and automatically categorizes the mentioned characteristic parameters based on exact categorization criteria for defining at least one of the following differentialforms of diastolic dysfunction of left ventricle in human beings: a) a diastolic Hypertensive differentialform; b) a diastolic Coronary differentialform; c) a diastolic Cardiomyopathic differentialform; d) a diastolic Congestive differentialform; e) a diastolic Advanced differentialform.
