Abstract: An apparatus and method for receiving digitized electrocardiographic (ECG) data, converting that data into a form suitable for reception by a facsimile device, and transmitting the data over a standard telephone line to a remote facsimile device. The apparatus includes an encased unit having modular connectors facilitating ready hookup to a telephone, a wall-type phone jack, a power source and a recording unit. The unit remains interconnected between the telephone and phone line, but is transparent to the operator and outside callers during normal telephone use. To facilitate easy use by the operator, a remote programmability feature is provided so that various user parameters stored in the apparatus may be accessed and reprogrammed from a remote touch-tone telephone.

Abstract: A portable apparatus having electronic circuitry for selectively monitoring and recording a user's electrocardiographic (ECG) data signals, wherein a first conductive electrode is disposed on a first surface of the apparatus casing for contact with an ECG lead position on the user's body and second and third paste-on electrodes are attached on the user's chest in positions which form the second and third electrodes in the standard Eindhoven triangle formation. A wristband is provided for securing the apparatus to the user's wrist and a microprocessor controls the electronic circuitry such that the user's ECG signal is monitored/recorded from six standard input channels. A modem device is attachable to the apparatus for effecting burst mode transmission of data to an external receiver.

Abstract: A portable apparatus having electronic circuitry for selectively monitoring and recording a user's ECG signals, wherein a first conductive electrode is disposed on a first surface of the apparatus casing for contact with an ECG lead position on the user's body and second and third electrodes are disposed on at least one other surface of the casing for ease of contact by a thumb and finger, respectively, of the user's hand. One of the second and third electrodes provides a ground signal source for the electronic circuitry. A wristband is provided for securing the apparatus to the user's wrist and a microprocessor controls the electronic circuitry such that the user's ECG signal is monitored/recorded only when the user grasps the second and third electrodes. A separate modem device is attachable to the apparatus for effecting burst mode transmission of data to an external receiver.
