Patent ID: 7054686

Claim:
A process for stimulating tissue selected from the group consisting of cardiac tissue, nerve tissue, brain tissue, and combinations thereof, comprising: delivering an electrical stimulating signal to the tissue, the electrical stimulating signal having about 10 to about 1,000 individual pulses, the individual pulses forming a first set of pulses and a second set of pulses, each individual pulse having a duration of from about one microsecond to about 100 microseconds, the individual pulses being discontinuous, with a spacing between adjacent pulses of at least from about 1 microsecond to about 100 microseconds, and the individual pulses each having a voltage of from about 10 millivolts to about 100 volts, the first set of pulses having a first voltage of about 10 millivolts to about 100 volts, the second set of pulses having a second voltage of about 10 millivolts to about 100 volts, the first voltage being different from the second voltage.
