Claim:
1. A method for delivering an electrical stimulation pulse to tissue, said method comprising: directing an acoustic transmission to a receiver-stimulator having circuitry including an envelope detector, wherein the acoustic transmission comprises an envelope and is powered by circuitry including an energy storage capacitor; producing an electrical stimulation pulse, by the receiver-stimulator, wherein the electrical stimulation pulse is configured with a voltage proportional to the amplitude of the envelope of the acoustic transmission; and delivering the electrical stimulation pulse to tissue using electrodes having a tissue-electrode impedance; wherein the capacitance of the energy storage capacitor is selected to produce an acoustic transmission with an envelope of decreasing amplitude, wherein the stimulation pulse is delivered to cardiac tissue to effect pacing and wherein the acoustic transmission has an envelope selected to compensate for the tissue-electrode impedance.
