PROBLEM TO BE SOLVED: To provide a device that allows a cardiac murmur that may indicate a disease such as aortic stenosis to be automatically detected without requiring experience.SOLUTION: A systolic phase cardiac murmur detection device includes an electrocardiogram signal reception part for receiving an electrocardiogram signal, a cardiac sound signal reception part for receiving a cardiac sound signal, a systolic phase extraction part for extracting a time of a cardiac systolic phase from the electrocardiogram signal, and a systolic phase cardiac murmur determination part for detecting whether or not a sound other than the first sound and/or the second sound is present in a cardiac sound in the time extracted by the systolic phase extraction part from a cardiac sound signal, and determines whether or not a cardiac murmur is present based on the detection result.SELECTED DRAWING: Figure 5【課題】経験がなくても、自動的に大動脈弁狭窄症等の疾患の恐れがある心雑音を検出できる装置を提供することを課題とする。【解決手段】収縮期心雑音検出装置として、心電図信号を受け付ける心電図信号受付部と、心音信号を受け付ける心音信号受付部と、前記心電図信号から心臓の収縮期の時間を抽出する収縮期抽出部と、前記心音信号から、前記収縮期抽出部が抽出した時間において心音における一音及び／又は二音以外の音が存在するかどうかを検知し、当該検知結果に基づいて心雑音が存在するかどうかを判定する収縮期心雑音判定部とを設ける。【選択図】 図５
