Claim 0:
1. A vagus nerve stimulator for treating chronic cardiac dysfunction, comprising:
an implantable neurostimulator comprising:
a pair of helical electrodes;
a nerve stimulation therapy lead electrically coupled to the pair of helical electrodes;
a pulse generator configured to deliver electrical therapeutic stimulation comprising a stimulation waveform applied to both of the helical electrodes via the nerve stimulation therapy lead; and
a recordable memory configured to store stimulation parameters comprising a programmable ON-time during which the pulse generator delivers the electrical therapeutic stimulation, a programmable OFF-time during which the electrical therapeutic stimulation is inhibited, and a periodic duty cycle comprising a percentage calculated from a ratio of the ON-time to the OFF-time;
wherein the periodic duty cycle is within a duty range selected based on a targeted therapeutic efficacy and an extent of potential side effects; and
wherein the pulse generator is further configured to operate under the stimulation parameters stored in the recordable memory.
