A system for long-term non-invasive heart monitoring includes (1) a disposable unit that has built-in electrodes, a built-in wire antenna, a watertight chamber that can be opened and closed, and an adhesive surface for cutaneous mounting (2) an electronic controller that can acquire, process and store physiological signals, and can be fitted into the disposable unit to establish electrical contact with the built-in electrodes and (3) a portable communication unit that can wirelessly communicate bi-directionally with the electronic controller, and further communicate bi-directionally with a remote service center.
