1. A method for cardiac pacing, said method comprising directing vibrational pacing energy at one or more regions of the left ventricle, wherein the vibrational energy selectively stimulates the left ventricle, wherein the vibrational pacing energy is delivered as single or multiple bursts having a frequency from 20 kHz to 5 MHz, a pulse duration from 0.12 μ
- sec to 13 msec, a duty cycle from 0.1% to 100%, and an intensity greater than 0.2 W/cm2.

Abstract
Systems for pacing the heart include a vibrational transducer which directs energy at the heart, usually at at least a ventricle, to pace the heart and to promote synchronized contraction of the ventricles. Optionally, additional vibrational and/or electrical stimulation may be provided. The vibrational transducers are usually implantable at a location proximate the heart.
