Abstract:
1. A system for the delivery of antitachycardia pacing to a patient's heart, comprising: at least one implantable receiver-stimulator adapted to contact at least one cardiac stimulation site, wherein the receiver-stimulator is present in a sealed case; and a subcutaneously implantable acoustic controller-transmitter, wherein the controller-transmitter is present in a separate sealed case from that of the receiver-stimulator, wherein the controller-transmitter is adapted to contain an electrogram signal processor and sensing electrodes for processing electrogram signals from the electrodes that are located on the exterior surface of the controller-transmitter and are in contact with tissue, and wherein the controller-transmitter is configured to detect a signal from a separate cardiac pacemaker, wherein the controller-transmitter is adapted to transmit acoustic energy upon detecting the signal from a separate cardiac pacemaker and the receiver-stimulator is adapted to receive the acoustic energy and convert the acoustic energy into cardiac stimulation energy based on both energy and signal information included in the received acoustic energy.
