Abstract:
1. Heart control apparatus for modifying the activity of at least part of a heart, comprising: (a) a sensor adapted for sensing a parameter characterizing the activity of at least part of the heart; (b) circuitry adapted to determining at least one of the parameters of a stimulus, said parameters being selected from the group comprised of the magnitude, shape, duty cycle, phase, frequency, duration, and time of application of said stimulus, wherein said determining is responsive to said sensed characterizing parameter and said circuitry is adapted to generate a stimulus comprising at least one non-excitatory portion, which is applied after a delay from the activation time of the portion at which said stimulus is applied, and is unable to generate a propagating action potential or prevent propagation of a propagating action potential and is adapted to modify contraction of said heart; and (c) at least one stimulus applying element adapted to apply said stimulus.
