A device for obtaining an electrocardiogram of a user includes a contralateral arm electrode for independent contact with one of a left arm and a right arm of the user； an ipsilateral arm electrode for independent contact with an other of the left arm and the right arm of the user； a leg electrode for independent contact with a leg of the user； a controller configured to sense electric potentials between the left arm, the right arm, the left leg, and/or a common electric point, representative of a central terminal； and determine one, or multiple components, of a frontal plane, six-lead electrocardiogram of the user based on the resulting signals of the sensed electric potentials.
