<P>PROBLEM TO BE SOLVED: To provide a low frequency therapeutic apparatus which outputs therapeutic pulses synchronized with rhythm of the autonomic nerve with a heartbeat as a base. Ž<P>SOLUTION: The low frequency therapeutic apparatus detects R, P, T, Q, S waves from an electrocardiographic waveform acquired by an electrocardiographic waveform detection part 2 (normally, an electrocardiograph) and produces respective gate signals in a gate signal generation part 4, corresponding to: (1) PQ time that is the systole of the atrium and a period wherein the influence of the parasympathetic nerve on an atrioventricular node is large; (2) RT time that is the systole of the ventricle and a period wherein the influence of the sympathetic nerve on a blood discharge amount is large; and (3) TP time that is the diastole of the ventricle and a period wherein a venous return is transmitted via the parasympathetic nerve. Actually required gate signal and interrupt signal are generated in an interrupt control part 5 according to output timing of the pulse set via a user interface 7. During a time when the gate signal is asserted, a main controller 6 having received the interruption drives a pulse generation circuit 8, an amplification circuit 9, and an output circuit 10 to output low frequency pulses to the subject.
