    • PROBLEM TO BE SOLVED: To provide an electrocardiac signal processing apparatus by which predetermined processes such as heart rate calculating process or others can surely be carried out without being affected by the electroconductivity of the warm water stored in a bathtub. SOLUTION: The apparatus comprises the heart rate detecting electrodes 31, 32, 33 located within the bathtub B for detecting the electrocardiac signal of a bather, the heart rate calculating unit 40 calculating the heart rate of the bather based on the electrocardiac signal detected by the these heart rate detecting electrodes 31, 32, 33, and the remote controller for a bath hot-water supply device displaying the heart rate of the bather calculated by the heart rate calculating unit 40. The heart rate calculating unit 40 comprises the amplifying circuit 44 amplifying the electrocardiac signal capable of varying the amplification rate, the microcomputer 45 calculating the heart rate from the amplified electrocardiac signal, and the electroconductivity sensor 47 for measuring the electroconductivity of the hot water storing in the bathtub B. The microcomputer 45 is adapted to automatically vary the amplification rate of the amplifying circuit 44 in response to the electroconductivity of the hot water storing the bathtub B.
