Analiza emisji akustycznej serca – zastosowanie w diagnostyce kardiologicznej

Summary
Heart auscultation is widely accepted procedure in the diagnosis of cardio-vascular diseases. Together with technical progress, precise tools have been created letting precise registration and analysis of the acoustic signal – stethoscope, phonocardiograph.
However, sounds that are processed by human ear constitute only a part of the acoustic emission of the heart. Device constructed by authors lets for spectrum analysis, in low-frequency scope. Performed measurements show that in infra-sound scope, heart accoustic spectrum reach the highest power. Research performed by authors is an introduction to the project, evaluating the adaptation of heart acoustic emission analysis in detection and monitoring of disease process, proceeding with the damage of the heart muscle.
