Provided is a circular breathing function measurement device mainly suitable for diagnosing the cardiovascular system including the heart, wherein said device acquires an electrocardiogram signal from an electrocardiogram sensor, and a heart sound signal and a breath sound signal and/or a blood-flow signal that include infrasonic sound (sound at a frequency lower than audible frequencies) from a sound sensor. The present invention comprises: a detection unit (1) provided with a sound sensor (11) and an electrocardiogram sensor (12); a signal processing unit (2) that processes signals from the detection unit (1); and a display unit (3) that outputs signals from the signal processing unit (2) as images. The electrocardiogram signals, the heart sound signals, and the breath sound signals and/or blood-flow sound signals are simultaneously displayed. |
