Abstract
Abstract Method and apparatus for acquiring and processing EKG signals. A plurality of electrodes for measuring a patient's cardiac electrical signals provide analog electrode signals to an analog-to-digital converter via a plurality of electrode wires. The analog-to-digital converter converts the analog electrode signals to corresponding digital electrode signals which are then combined into combined signal leads.
