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.
