Abstract

The present invention discloses a portable system for acquiring, processing, storage, diagnostics, remote alarm transmission and cardiac event in patients, which operates at a sampling rate of a minimum 1 kHz signals, making it quick and effective. The system is non-invasive and capable of detecting more than eight cardiac conditions, unlike other similar devices on the market.
