Procedure and means for telemetric measuring of heartbeat and ECG signal, using a magnetic proximity field
First Claim
1. A method for telemetric measurement of heartbeat signals whereby a person'"'"'s heartbeat signal is measured from a suitable part of the body and the signal generated is transmitted from a transmitter to a receiver by telemetric data transmission comprising the steps of:
- (a) applying electrodes attached to the transmitter against a person'"'"'s skin for detecting a heartbeat signal in said person'"'"'s body;
(b) amplifying the detected heartbeat signal, through amplifier means and generating a periodic low frequency signal dependent upon the detected and amplified heartbeat signal;
(c) generating a periodic three-dimensional low frequency magnetic proximity field by feeding said low frequency periodic signal to three mutually perpendicular magnetic coils provided in the transmitter.(d) detecting by means of an inductive coupling, said three dimensional magnetic field with a receiver having a magnetic coil structure similar to that of said transmitter;
(e) amplifying the signal received as induced in said receiver coils by a magnetic field generated by said transmitter coils;
(f) converting the received and amplified signal by known means to computer readable data;
(g) calculating the heartbeat value from said computer readable data by means of a computer interfaced with said receiving; and
(h) displaying the heartbeat value on means interfaced with said computer.

Abstract
A procedure and a means for telemetric measurement of heartbeat and ECG signal, according to the procedure a person'"'"'s heartbeat or ECG signal being measured in a suitable part of the body and transmitted from a separate transmitter means to a separate receiver means. The telemetric data transfer is carried out, using the magnetic proximity field, by controlling magnet coils in the transmitter unit, with the heartbeat or ECG signal detected in the body and amplified, the magnetic field produced by the magnet coils being essentially multidimensional, and by detecting in the receiver the magnetic field with a coil structure having at least partially an equivalent directional pattern of the magnetic field.
