1. A drug delivery system comprising:
- a cardiac device comprising a sensing channel for sensing electrical activity occurring in a patient'"'"'s heart and generating sensing signals in accordance therewith, circuitry for extracting information from the sensing signals, circuitry for detecting a particular medical condition from the extracted information and generating a command signal if the medical condition is present, a telemetry interface for receiving and transmitting radio frequency signals, and circuitry for modulating the radio frequency signals with information relating to the command signal; and
, an external drug delivery device for affixation to a patient having incorporated therein a telemetry interface for receiving and transmitting radio frequency signals, circuitry for demodulating radio signals to derive a command signal therefrom, and circuitry for controlling the drug delivery device in order to deliver a drug in accordance with the command signal.

Abstract
A drug delivery system incorporated into a cardiac device for delivering a dose of a drug to a patient upon detection of a particular medical condition. The cardiac device may be, for example, an implantable cardioverter/defibrillator, cardiac pacemaker, or combination device that communicates via a radio frequency link with a drug delivery device. The drug delivery device is preferably an electrically modulated transdermal drug delivery device for delivering the drug transdermally in accordance with a signal received from the cardiac device.
