1. An ECG measurement method for a vehicle, comprising:
recognizing contact of a body of a driver with a first electrode in contact with the body of the driver, and outputting a first electrode signal from the first electrode;
recognizing contact of the body of the driver with a second electrode, and outputting a second electrode signal from the second electrode;
outputting an ECG signal by differentially amplifying the first electrode signal and the second electrode signal;
evaluating quality of the ECG signal; and
adjusting impedance compensation of the first electrode signal or the second electrode signal based on evaluating the quality of the ECG signal and vehicle information,
wherein the vehicle information includes at least one of global positioning system (GPS) information, a vehicle speed, a temperature, or humidity.
