Electrocardiograph and additional lead ECG derivation method with additional guidance function

摘要

PROBLEM TO BE SOLVED: To provide an electrocardiograph with an additional lead function and an additional lead electrocardiogram (ECG) deriving method capable of easily deriving an ECG signal of an additional lead ECG through an arithmetic operation, based on ECG signals of a standard 12-lead ECG measured by a potential detector.;SOLUTION: An ECG memory 12 stores the ECG signals measured as the standard 12-lead ECG by the potential detector 10. An additional lead ECG calculating means 16 calculates extended lead ECGs V7-V9 from the ECG signals stored in the ECG memory 12, using coefficients α representing relationship among leads. The additional lead ECGs V7-V9 calculated are displayed on a display monitor 20 through an additional lead ECG waveform outputting means 18.;COPYRIGHT: (C)2008,JPO&INPIT
