PROBLEM TO BE SOLVED: To provide a cardiac sound measuring apparatus in which the measurement of murmur in two or more parts is unnecessary, and that can perform the analysis of the presence or absence of the heart disorder based on a second cardiac sound included in a cardiac sound signal measured in one location.SOLUTION: In the cardiac sound measuring apparatus, a second cardiac sound signal from a cardiac sound signal that a cardiac sound sensor 2 outputs is detected by a cardiac sound band extraction section 3, and a second cardiac sound division detector 5 detects the condition concerning the division of the second cardiac sound, including at least the presence or absence of the division of the second cardiac sound based on the second heart sound signal. Meanwhile, a second cardiac sound pattern storage 6 memorizes beforehand the information in which the heart disorder condition including the presence or absence of the heart disorder and the division condition of the second cardiac sound including the presence or absence of the division of the second cardiac sound are mutually related. A heart disorder determination section 9 determines the heart disorder condition including the presence or absence of the heart disorder based on: the condition concerning the division which the second cardiac sound division detector 5 has detected and the information memorized in the second cardiac sound pattern storage 6 beforehand.COPYRIGHT: (C)2012,JPO&INPIT【課題】複数箇所での心雑音の測定が不要で、一箇所で測定した心音信号に含まれる第2心音に基づいて心疾患の有無を解析できる心音測定装置を提供する。【解決手段】この心音測定装置では、心音帯域抽出部3によって、心音センサ2が出力する心音信号から第2心音信号を検出し、第2心音分裂検出部5が上記第2心音信号に基づいて、少なくとも上記第2心音の分裂の有無を含む上記第2心音の分裂に関する状態を検出する。一方、第2心音パターン記憶部6は、心疾患の有無を含む心疾患状態と第2心音の分裂の有無を含む第2心音の分裂状態とを互いに関連付けた情報として予め記憶している。心疾患判定部9は、第2心音分裂検出部5が検出した分裂に関する状態と、第2心音パターン記憶部6に予め記憶された上記情報とに基づいて、心疾患の有無を含む心疾患状態を判定する。【選択図】図1
