Portable ECG monitor/recorder
First Claim
1. A wrist-worn, encased apparatus having electronic circuitry for selectively monitoring, recording and transmitting a user'"'"'s electrocardiographic (ECG) signals, wherein an electrode arrangement is provided for acquiring said ECG signals, said arrangement comprising:
- a first conductive electrode 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 conductive electrodes disposed on at least one other surface of the apparatus casing and positioned for ease of contact by the user'"'"'s hand when the first electrode is placed in contact with an ECG lead position on the user'"'"'s body, wherein one the second and third electrodes provides a ground signal source for the electronic circuitry, and wherein the electronic circuitry is activated only when the user touches the three electrodes.

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.
