Abstract: A signal measurement method and a signal measurement apparatus (1000) are provided. A mode selection switch (11) may be used to enable a multi-lead measurement mode, to obtain signals of a plurality of leads and a status of a user. When quality of the signals of the plurality of leads is good or the user is in a static state, extracted features of the signals of the plurality of leads are output. When the signals of the plurality of leads are poor and the user is in a moving state, the mode selection switch (11) is used to switch to a single-lead mode with right leg drive, to obtain a signal of a single lead. A common-mode signal is eliminated from the signal of the single lead by using a negative feedback of a right leg drive electrode, and a feature of the signal of the single lead is output.
