Title: Implantable cardiac stimulation system providing high output far-field pacing and method

Abstract: An implantable cardiac stimulation device provides therapy for hearts having severe conduction abnormalities such as hearts suffering from congestive heart failure. The implantable cardiac stimulation device includes a pulse generator that provides pacing pulses having energies greater than about 0.1 millijoules and a lead system including a far-field electrode configuration that applies the pacing pulses to the heart. The lead system may further provide a near-field pacing electrode configuration and the device switches between the near-field pacing electrode configuration and the far-field pacing electrode configuration responsive to the measurement of a hemodynamic parameter such as QRS width.
