Abstract

A method of estimating pulmonary artery pressures of a patient, comprising: detecting second heart sounds; determining pulmonary components and aortic components responsive to the second heart sounds; determining a splitting interval between the pulmonary components and the aortic components; determining a cardiac interval of the patient; determining a normalized splitting interval responsive to the splitting interval and the cardiac interval; and determining pulmonary artery pressure responsive to the normalized splitting interval.
