Abstract

Abstract An electrocardiographic data transmission system using a telephone equipment includes an electrocardiograph (6) detecting a body surface potential signal varying with heart beats of the subject person (1) and outputting a sound pressure signal converted from the body surface potential signal into the telephone equipment (3), and a signal converter (10) coupled to the telephone equipment (5) of the specified hospital (4) receiving the sound pressure signal from the electrocardiograph (6), and outputting the body surface potential signal converted from the sound pressure signal to the display (11, 12). The system enables immediate diagnosis by transmitting the electrocardiographic data of the subject person (1) who falls into an urgent condition outside of the hospital (4) via telephone equipment (3, 5, 7, 8, 9) in real time to the cardiographic data analyzer (11) of the hospital.

Claims Analysis

Total Claims: 3
Claim 1
Independent Claim 134 words
An electrocardiographic data transmission system for use with telephone equipment comprising: an electrocardiograph (6) provided with electrodes for detecting a body surface potential signal varying with heart beats of a subject person (1) and outputting a sound pressure signal converted from the detected body surface potential signal and which can be transmitted via a telephone (3); a signal converter (10) for connection to telephone equipment (5) to receive the sound pressure signal transmitted via the telephone system (7, 8, 9) from the electrocardiograph (6) and outputted from the receiving telephone equipment (5) and to output a body surface potential signal converted from the sound pressure signal; and a display (11, 12) which receives the body surface potential signal outputted from the signal converter (10) and displays the electrocardiographic wave of the subject person (1).
Claim 2
Dependent Claim 79 words
An electrocardiographic data transmission system according to claim 1, further comprising a first telephone equipment (3) at the side of the subject person for transmitting via a telephone line (7, 9) the sound pressure signal from the electrocardiograph (6) set on a telephone transmitter (3A), and a second telephone equipment (5) for receiving the sound pressure signal in correspondence with the call from the telephone equipment (3) at the side of the subject person (1) via the telephone line.
Claim 3
Dependent Claim 28 words
An electrocardiographic data transmission system according to claim 1 or 2 wherein the cardiograph (6) is adapted to be attachable to a telephone transmitter (3A) with one touch.
