Abstract
Disclosed in an implantable cardioverter having the capability of communicating with its wearer. In one specific embodiment, the cardioverter is an automatic, fully implantable ventricular defibrillator including an electrical stimulator to deliver a mild shock to the wearer to inform the wearer, for example, that fibrillation has been sensed. In another embodiment, communication from the implanted defibrillator to the wearer is by means of an implanted audio transducer. And in a third embodiment the implanted defibrillator communicates with the wearer by issuing a mechanical vibration. Also disclosed is a mechanism whereby the wearer is able to disenable the defibrillator, and prevent the delivery of a defibrillating pulse.
