Abstract
Abstract A method of diagnosing the heart condition of a living body moving in the water, in which an electrocardiogram recorded by the steps of hermetically contacting electrodes on the skin surface of the body moving under water, detecting an electrocardiac signal by the electrodes, leading the detected electrocardiac signal through lead wires to a wireless transmitter on the living body, remotely receiving the radio electrocardiac signal transmitted from the transmitted by a receiver, and recording the electrocardiogram on the basis of the radio electrocardiac signal received by the receiver.

Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
165 words
A method of diagnosing the heart condition of a living body during exercise in water comprising the steps of: (a) providing at least one suction disc having mounted thereon a hermetically sealed electrode surrounded by an annular body surface adherent strip, said sealed electrode being in non-contacting circumferential relationship with said annular strip; (b) placing said suction disc with said hermetically sealed electrode on a living body to be moving in the water, the disc being held firmly to the moving body by vacuum forces effected from the suction disc and adhesive forces effected circumferentially around said sealed electrode due to said adherent strip; (c) detecting an electrocardiac signal from said hermetically sealed electrode while said body is moving in the water; (d) leading the detected electrocardiac signal from the electrode through lead wires to a radio transmitter mounted on the living body; (e) receiving the radio-transmitted electrocardiac signal by a receiver; and (f) recording an electrocardiograph derived from the signal received by the receiver.
