Abstract
A multi-lead electrocardiogram detection method and an electronic device. The method includes: obtaining potential signals of surfaces of two upper limbs and a lower limb of a human body and six equivalent positions on a chest of the human body in response to a user operation, and determining electrocardiogram signals corresponding to twelve leads based on the potential signals. The user operation is an operation that first and second detection electrodes are in contact with the two upper limbs of the human body, and the third detection electrode is in contact with the lower limb of the human body and the six equivalent positions on the chest in sequence.
