PROBLEM TO BE SOLVED: To provide a vital reaction recording device by solving the problems that, while a medical value of a mechanocardiogram is recognized as high, a mechanocardiogram recording device is large and extremely expensive, and the measurement performance thereof is also poor, and that at least two medical professionals are required for performing the measurement only in a special environment such as a sound proof room so that effective data for a measured living body truly needing the diagnosis using the mechanocardiogram cannot be obtained, and the mechanocardiogram recording device is not considered useful for the diagnosis of a circulatory system.SOLUTION: There is provided a vital reaction recording device that is small-sized and inexpensive like a notebook-sized personal computer capable of measuring an apex cardiogram, etc. fully utilizing a two-dimensional sensor capable of measuring a pressure change in a plurality of places adjacent to a living body simultaneously with respect to one pulsation to be measured, an electronic device of a personal computer level, and a memory, storing and using the temporal course of the living body information, and displaying the living body information as a digital image.SELECTED DRAWING: Figure 1
