SHUNT MURMUR ANALYSIS DEVICE, SHUNT MURMUR ANALYSIS METHOD, COMPUTER PROGRAM, AND RECORDING MEDIUM

摘要

A shunt murmur analysis device comprising: an acquisition means (110) that obtains shunt murmur information relating to shunt murmurs at a shunt formation site in a measurement subject; a calculation means (130) that calculates, on the basis of the shunt murmur information, both the size of shunt murmurs at a first frequency and the size of shunt murmurs at a second frequency that is lower than the first frequency; and an output means (140) that outputs evaluation information relating to evaluation of shunt murmurs, on the basis of the size of shunt murmurs at the first frequency and the size of shunt murmurs at the second frequency. As a result, diagnosis of stenosis at shunt formation sites can be suitably supported.
