ABSTRACT:
There are provided an electrocardiograph with an extended lead function and an extended lead ECG deriving method capable of easily deriving an ECG signal of an extended lead ECG by an arithmetic operation, based on ECG signals of a standard 12-lead ECG measured by a potential detector10. An ECG memory12stores the ECG signals measured as the standard 12-lead ECG by the potential detector10. An extended lead ECG calculator16calculates extended lead ECGs V7-V9from the ECG signals stored in the ECG memory12, using coefficients α representing a relationship among leads. The extended lead ECGs V7-V9calculated are displayed through an extended lead ECG waveform outputting device18on a display monitor20.
