Abstract: A receiver apparatus adapted to have coupled thereto intentionally transmitted signals, each being characterized as having a predetermined number of pulsations, which are transmitted over a communication link such as the standard switched telephone network and, at times, noise signals which are introduced into the communication link. The receiver includes measuring means arranged to measure the time interval between successive signals coupled thereto, and signal verification means to verify that each signal coupled to the receiver is either an intentionally transmitted signal or a noise signal. In the event that a noise signal is coupled to the receiver, the signal verification means is arranged to abort measurements of the measuring means. Measurements not aborted are indicative of the time interval between each two successive intentionally transmitted signals coupled to the receiver.

Abstract: Apparatus is provided for sensing physiological potentials of a living body. There is provided a first band for at least partially encircling a part of the living body and having a first electrode mounted thereon. The first electrode is adapted for connection to an instrument for amplifying the physiological potentials of the living body. A second band is provided for at least partially encirling another part of the living body and has a second and a third electrode located thereon. The second and third electrodes each are adapted for connection to the instrument for amplifying the physiological potentials of the living body.

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.
