Summary:
Our cosideration: sinusoidal pacing of a sick sinus node in the heart is to be preferred over a train of pulses one. We concentrate on some stimulation on a BVP system, and on the complex Yanagihara-Noma-Irisawa system. The interesting results obtained are: 1) For a range of forcing frequencies the phase trajectory deforms near the bottom left and the upper right corners which gradually develop into "bulges"; 2) The time spent in the part of the trajectory not including the bulges remains constant for a whole range of stimulating periods.
