PROBLEM TO BE SOLVED: To provide an electrocardiographic processor capable of ensuring prescribed processing such as heart rate computing processing even when base line oscillation has occurred to an electrocardiographic signal. SOLUTION: This electrocardiographic signal processor is provided with heartbeat detecting electrodes 31, 32, 33 installed in a bathtub B to detect the electrocardiographic signals of a bathing person; a heart rate computing unit 40 for computing the heart rate of the bathing person on the basis of the electrocardiographic signals detected by the heartbeat detecting electrodes; and an operating remote control for a bath water heater displaying the heart rate of the bathing person prepared by the heart rate computing unit 40. The heart rate computing unit 40 has a differential amplifying circuit 42 for differentially amplifying the electrocardiographic signals from the heartbeat detecting electrodes 31, 32, 33, and a reference level stabilizing circuit 47 composed of a negative feedback circuit which applies negative feedback to the input side in the reversed sign state of a frequency component lower than the electrocardiographic signal, from the output of the differential amplifying circuit 42. |
