Abstract
A system for detection of frequency power for diagnosing coronary artery disease (CAD), comprising: an acoustic sensor to be placed on the chest of a patient to generate acoustic signals S: a memory adapted to store acoustic signals S; a control unit adapted to receive said acoustic signals S; the control unit comprising: an identification unit to identify diastolic or systolic periods in a predetermined time period and to generate a period signal S, a filtering unit adapted to apply a filter to said identified periods to generate a low frequency band signal Sindicating low frequency bands of identified periods; a calculation unit to estimate the power in said low frequency band of identified periods, to calculate a low frequency power measure and to generate a low frequency power measure signal S. The invention also relates to a stethoscope and a method for detection of low frequency power.
