摘要：
The present disclosure relates to a method, an apparatus and a computer program for noninvasively determining a cause of a blood pressure change. The method includes at least: obtaining maximum amplitudes of heart sounds； monitoring changes in the maximum amplitudes； estimating change amounts of indexes on a myocardial contractile force and on vascular resistance, based on increasing or decreasing of a blood pressure of the patient, and the changes in the maximum amplitudes； and determining the cause of the blood pressure change of the patient as an effect of at least one of alpha action, alpha blockage, beta action and beta blockage, based on results of the estimation of the first change amount of the first index, the second change amount of the second index and the third change amount of the third index.
