Abstract:
1. A handheld device adapted for placement against the body of a patient in a measurement position to thereby extract special ECG signals for combining with a predetermined calibration matrix in order to construct an ECG, the handheld device comprising: at least three integrated active electrodes, including first and second integrated active electrodes adapted to electrically contact the chest of the patient in the measurement position, and a third integrated active electrode adapted to electrically contact the left hand of the patient in the measurement position; and a integrated fourth electrode adapted to electrically contact the right hand of the patient in the measurement positions wherein said integrated active electrodes and integrated fourth electrode are disposed in the device such that, when in the measurement position, said contact with the chest of the patient by the first and second integrated active electrodes, with the left hand of the patient by the third integrated active electrode, and with the right hand of the patient by the integrated fourth electrode, is operative to achieve maximum recording point vector orthogonality, to thereby optimize ECG reconstruction.
