Portable ECG monitor/recorder
First Claim
1. A system for selectively monitoring and recording a user'"'"'s ECG data and transmitting such data to an external receiving station, comprising:
- a portable recording unit having a casing which encloses electronic elements, including processing means, a power source and a first memory, and which carries three conductive electrodes that are electrically coupled to the electronic elements, a first one of the electrodes being disposed on a first surface of the casing for contact with an ECG lead position on the user'"'"'s body and the other two electrodes being disposed on at least one other surface of the casing and positioned for ease of contact by the user with a thumb and finger, respectively, of a hand, whereby the unit monitors and processes the user'"'"'s ECG data and stores it in memory only when the first electrode contacts a body lead position and the second and third electrodes are grasped by the user; and
a modem which is adapted for electrical connection to the recording unit, comprising circuit means for processing the ECG data into a format which can be transmitted for analysis to the external receiving station and means for transmitting the processed ECG data to the external receiving station.

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.

15. A system for selectively monitoring and recording a user'"'"'s electrocardiographic (ECG) data and transmitting such data to an external receiving station, comprising:
-
a wrist-worn recording unit having a casing with front, back and side surfaces which encloses electronic elements, including processing means, a power source and a first memory, and which carries a pair of conductive electrodes that are electrically coupled to the electronic elements, one of the electrodes being disposed on the back surface of the casing such that it lies in continuous electrical contact with the user'"'"'s wrist and the second electrode being disposed on a surface of the casing other than the back surface and positioned for ease of contact by the user with the hand opposite the contacted wrist, whereby the unit monitors and processes the user'"'"'s ECG data and stores it in memory only when the user touches the second electrode; and a modem adapted to receive ECG data from the first memory of the recording unit, comprising circuit means for processing the ECG data into a format which can be transmitted for analysis to the external receiving station and means for transmitting the processed ECG data to the external receiving station. - View Dependent Claims (16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26)

27. A system for selectively monitoring and recording a user'"'"'s electrocardiographic (ECG) data and transmitting such data to an external receiving station, comprising:
-
a wrist-worn recording unit having a casing which encloses electronic elements, including a processing means, a power source and a first memory, and which carries first and second conductive electrodes that are electronically coupled to the electronic elements, the electrodes being disposed on different exterior surfaces of the recording unit, whereby the unit monitors and processes the user'"'"'s ECG data and stores it in memory only when the user touches both of the electrodes; and a modem adapted to receive ECG data from the first memory of the recording unit, comprising circuit means for processing the ECG data into a format which can be transmitted for analysis to the external receiving station and means for transmitting the processed ECG data to the external receiving station. - View Dependent Claims (28, 29, 30, 31, 32, 33)
