Claim 0:
1. An electrocardiogram measurement apparatus, comprising:
a first electrode and a second electrode configured to receive two electrocardiogram voltages of two body parts in contact therewith, respectively;
two amplifiers configured to receive the two electrocardiogram voltages from the first electrode and the second electrode, respectively;
one electrode driver configured to output a driving voltage;
a third electrode configured to receive the output of the electrode driver and transmit the output of the electrode driver to a third body part in contact therewith;
a current detector connected to an electrode among the first, second, and third electrodes;
an AD converter connected to an output terminal of each of the two amplifiers to convert output signals of the two amplifiers into two digital signals;
a microcontroller configured to receive the two digital signals of the AD converter;
a communication means configured to transmit the two digital signals; and
a case of the electrocardiogram measurement apparatus,
wherein:
the microcontroller is supplied with power from a battery;
the microcontroller controls the AD converter and the communication means;
the two amplifiers each receive and amplify one electrocardiogram voltage simultaneously;
using the two electrocardiogram voltages, four electrocardiogram voltages are additionally obtained to obtain a total of six electrocardiogram voltages;
the six electrocardiogram voltages are displayed on a smartphone screen;
the case is flat and one side is longer than the other; and
two electrodes among the first, second, and third electrodes are arranged on the upper surface of the case, and an electrode among the first, second, and third electrodes is arranged on the lower surface of the case.
