<p>The present invention relates an electrocardiography system having an isolated measurement head from which are electrodes attached to a patient so that the accuracy of the electrocardiographic test may be improved without an electric shock. An electrocardiography according to the present invention comprises: a measuring head for receiving electrocardiographic signals sensed by the sensing electrodes and for generating difference voltages signals from the received electrocardiographic signals, wherein the isolated measuring head is driven by a first power supply; a transmission link for transmitting the difference voltage signals; and an induced voltage generator for receiving difference voltages signals via the transmission link and for generating induced voltage signals, wherein the measuring head is electrically isolated from the induced voltage generator and wherein the induced voltage generator is driven by a second power supply.</p> |
