Abstract
Abstract A monitor apparatus is disclosed for monitoring electrical stimulation signals due to either natural or artificial electrical stimulation of a body part via a communication link such that the repetition rate of the electrical stimulation signals can be determined. The monitor apparatus comprises the subsystems: a transducer; a communication link or network; and a reciever. The transducer is adapted to sense the electrical stimulation signals generated either naturally or by an electronic organ stimulator, such as an implanted cardiac pacer, and to convert the electrical stimulation signals to audible signals such as tone bursts. These audible tone bursts are then transmitted over a communication link such as the standard telephone network to the receiver located at a remote telephone station, typically a cardiologist''s office. The receiver is adapted to measure the time interval between received tone bursts. The receiver is further adapted to display or indicate to an observer the time interval between received tone burst. If desired, the receiver can be adapted to indicate directly the repetition rate of the stimulation signals. The information is then utilized by an observer for diagnostic purposes. The monitor apparatus also includes a test means for testing the integrity of the apparatus including the transducer, the communication link and the receiver.
