Apparatus and method for remotely monitoring implanted cardioverter defibrillators
First Claim
1. An apparatus for remotely interrogating and monitoring the operation of a cardioverter defibrillator of the type which emits, upon enablement, audio tone signals coincident with sensed events, said apparatus comprising:
- a) telephone communication means for receiving differing commands from a central monitoring facility by way of a telephone communication channel thereby providing differing telephone received commands and transmitting data to said central monitoring facility by way of said telephone communication channel;
b) means for acquiring differing patient electrocardiogram signals and coupling same to said telephone communication means for transmission to said central monitoring facility;
c) detector means, responsive to said differing telephone received commands received from said central monitoring facility by way of said telephone channel, for selectively enabling the emission of said audio tone signals wherein said audio tone signals are representative of selected electrocardiogram signals of said acquired electrocardiogram signals thereby providing said remote interrogating and monitoring of said cardioverter defibrillator by said central monitoring facility; and
,d) means for detecting said audio tone signals and coupling same to said telephone communication means for transmission to said central monitoring facility.

Abstract
An apparatus for remotely monitoring the performance of an implanted cardioverter defibrillator includes a remote apparatus adapted which receives commands from and transmits data to a central monitoring facility over telephone communication channels. The remote apparatus includes equipment for acquiring a patient'"'"'s ecg waveform and transmitting that waveform to the central facility over the telephone communication channel. The remote apparatus also includes a segment, responsive to a command received from the central monitoring facility, for enabling the emission of audio tone signals from the cardioverter defibrillator. These audio tones are detected and sent to the central monitoring facility via the telephone communication channel. The remote apparatus also includes patient alert devices which are activated by commands received from the central monitoring facility over the telephone communication channel.
