Arrhythmia Research Technology, Inc. Announces Results for First Quarter 2008

FITCHBURG, MA--(Marketwire - May 15, 2008) - Arrhythmia Research Technology, Inc. (the "Company") (AMEX: HRT) and its wholly owned subsidiary Micron Products, Inc. ("Micron") reported total revenue of $5,460,000 and net income of $149,000 for the quarter ended March 31, 2008 compared to total revenue of $5,009,000 and net income of $234,000 for the same quarter of 2007. Net income per share for the three months ended March 31, 2008 decreased to $ 0.06 per share from $ 0.09 per share for the same period in 2007.

Increases in the cost of manufacturing and price erosion in the highly competitive sensor and custom injection molding markets are the primary cause for the over 30% decrease in net income and earnings per share for the quarter ending March 31, 2008 compared with the same period in 2007. Additionally, in preparation for Sarbanes Oxley Section 404 compliance, the Company is experiencing an increase in corporate costs. This includes an enterprise management software system implementation and Section 404 compliance specific costs which we began to expend in the fourth quarter of 2007 and which will continue through at least the third quarter of 2008.

James E. Rouse, the Company's President and CEO commented, "Although we are encouraged by our increase in revenue, management is focused on improving gross margin on existing product lines through technological and process improvements along with developing new business with higher gross margin potential. We remain very confident that our long term diversification strategy, including acquisitions, and our investment in capital equipment and resources will result in continuing growth. Higher profit from projects and programs in development or early stage production are expected to positively affect our margins over the long term."

The Company, through Micron, manufactures silver plated and non-silver plated conductive resin sensors and distributes metal snaps used in the manufacture of disposable ECG, EEG, EMS and TENS electrodes. Micron's NEM division manufactures custom injection molded products for medical, electronic, industrial and consumer applications. Micron's MIT division provides end-to-end product life cycle management through a comprehensive portfolio of value-added services such as design, engineering, prototyping, manufacturing, machining, assembly and packaging.
