First Claim
1. A biological signal measuring apparatus comprising:
- a first unit measurer configured to measure a first biological signal of a subject based on an electrical characteristic difference between first electrodes contacting the skin of the subject;
a second unit measurer configured to measure a second biological signal of the subject based on an electrical characteristic difference between second electrodes contacting the skin of the subject at positions different from positions of the first electrodes; and
a biological signal generator configured to generate a biological signal by arithmetically summing the measured first and second biological signals based on points on a time axis of a graphical display of the first biological signal or intervals obtained by combining the points, wherein;
the first unit measurer and the second unit measurer are arranged based on characteristics of contact parts of the first and second electrodes,the first electrodes and the second electrodes are located on a line of induction,the first and second biological signals are synchronized in time during the summing such that the sum of their potentials is greater than the potential of either the first biological signal or second biological signal,the points include at least one of a point at which a P wave starts, a point at which the P wave ends, a point at which a Q wave starts, a point at which the Q wave ends, a point at which a R wave starts, a point at which the R wave ends, a point at which a S wave starts, a point at which the S wave ends, a point at which a T wave starts, and a point at which the T wave ends, andthe first and second biological signals are further based on intervals obtained by combining the points among the points on a time axis of a graph of the first biological signal.
