Claim 15:
16. An electrocardiogram measurement apparatus, comprising:
a first electrode, a second electrode, and a third electrode configured to receive three electrocardiogram voltages of three body parts in contact therewith, respectively;
three amplifiers configured to receive the three electrocardiogram voltages from the first electrode, the second electrode, and the third electrode, respectively;
an electrode driver configured to output a driving voltage;
a fourth electrode configured to receive the output of the electrode driver and transmit the output of the electrode driver to a fourth body part in contact therewith;
a current detector connected to at least one of the four electrodes;
an AD converter connected to an output terminal of each of the three amplifiers to convert output signals of the three amplifiers into three digital signals;
a microcontroller configured to receive the three digital signals of the AD converter; and
a communication means configured to transmit the three digital signals,
wherein:
the microcontroller is supplied with power from a battery;
the microcontroller controls the AD converter and the communication means;
the three amplifiers each receive and amplify one electrocardiogram voltage simultaneously; and
a case of the electrocardiogram measurement apparatus is flat and one side is longer than the other.
