PROBLEM TO BE SOLVED: To appropriately detect various characteristic portions in a cardiac sound from a cardiac sound signal including a murmur.SOLUTION: A cardiac murmur analyzing signal generation unit 210 generates a cardiac murmur analyzing signal for analyzing a cardiac murmur that constitutes a cardiac sound. A cardiac murmur detection unit 310 detects the cardiac murmur on the basis of the cardiac murmur analyzing signal generated by the cardiac murmur analyzing signal generation unit 210. The cardiac murmur detection unit 310 comprises a cardiac murmur sounding section detection unit 311 and a cardiac murmur contour determination unit 312. The cardiac murmur sounding section detection unit 311 uses the cardiac murmur analyzing signal to detect a cardiac murmur sounding section, and the cardiac murmur contour determination unit 312 determines whether or not the cardiac murmur analyzing signal falls under the cardiac murmur on the basis of the contour of the cardiac murmur in the cardiac murmur sounding section. |
