FITCHBURG, MA--(Marketwire - February 22, 2010) - Arrhythmia Research Technology, Inc. (the "Company" or "ART") (NYSE Amex: HRT) is pleased to announce it has entered into a multi-year software license agreement with Nihon Kohden Corporation ("Nihon") (TSE: 6849) of Tokyo, Japan. Under the agreement the Company has granted Nihon a non-exclusive and restricted right and license to use, sell and sub-license the Company's proprietary signal-averaging electrocardiography (SAECG) software, PREDICTOR, customized for exclusive use in Nihon's electrocardiogram and other ECG-related products.

James E. Rouse, the Company's President and CEO commented, "We are very pleased to announce that Nihon is the first OEM to license our customizable PREDICTOR SAECG analysis software. This agreement, which has an initial term of five years, is the result of a long and cooperative development project between our two companies. Signal-averaged electrocardiographic analysis is a very valuable risk stratification tool for electrophysiologists and cardiologists in the management of post myocardial infarction patients. ART's PREDICTOR software is considered by the American College of Cardiology and the American Heart Association to be the 'Gold Standard' in signal-averaged electrocardiography analysis. We are very proud that PREDICTOR and the ART name are now associated with Nihon, Japan's largest manufacturer and supplier of medical electronic equipment. Fees associated with this agreement are expected to contribute to revenues beginning in the second quarter of 2010."

A signal-averaged electrocardiogram detects cardiac microvolt signals. Signal averaging, which improves the signal to noise ratio, is a well-recognized technique for detecting and analyzing such cardiac microvolt signals including ventricular late potentials. High resolution acquisition equipment is used to collect the microvolt signals and transfer the data to an analytical system. ART's patented PREDICTOR software filters and analyzes the data to present the signal-averaged ECG for interpretation by a cardiologist.
