ABSTRACT:
The present invention provides a cardiac pacing system based on biological activities, comprising: a) at least one nerve activity sensing means which senses nerve activity of a cardiac sympathetic nerve and/or a vagal nerve, and outputs a plurality of input nerve activity signals; b) a calculating means which receives the input nerve activity signals, calculates a transfer function by computing a Fourier transform of normal nerve activity signals and a normal heart rate signal from normal cardiovascular system, calculates an impulse response by computing an inverse Fourier transform of the transfer function, calculates a plurality of pacing signals for control of a heart rate using a convolution integral between the input nerve activity signals and the impulse response, and outputs the pacing signals; and c) a pacing means which receives the pacing signals, and stimulates the heart based on the pacing signals such that heart rate is regulated.
