Item 1.01 Entry into a Material Definitive Agreement.

As of April 4, 2012, Arrhythmia Research Technology, Inc. (“ART”) and its wholly owned subsidiary, Micron Products, Inc. (“Micron”) (collectively, the “Company”) entered into an Amended and Restated Loan and Security Agreement (the “Agreement”) and an Amended and Restated Revolving Demand Note (the “Note” and with the Agreement, the “Loan Documents”) with RBS Citizens, N.A., a national banking association (“RBS”) (successor by merger to Citizens Bank of Massachusetts) with respect to modification of the $3 million revolving loans and letters of credit available to Micron. The Agreement amends and restates the Unsecured Revolving Demand Line of Credit Agreement entered into in December 2003 between Micron and Citizens Bank of Massachusetts. Pursuant to the Agreement, ART was added as a Borrower on a joint and several basis with Micron and certain assets of the Company serve as collateral to secure the repayment of any revolving loans outstanding from time to time, namely, among other things, accounts receivable, inventory, cash and deposit accounts, together with proceeds thereof and records, insurance proceeds, refunds and rebates.

Each advance under the Loan Documents shall be the Company's choice of a LIBOR Rate Loan or a LIBOR Advantage Loan, as such terms are defined in the Loan Documents, and is repayable upon demand by RBS. LIBOR Rate Loans outstanding shall accrue interest equal to the Adjusted LIBOR Rate (determined by dividing the LIBOR Rate by 100% minus the LIBOR Reserve Percentage under regulations of the Board of Governors of the Federal Reserve System) plus a LIBOR Rate Margin of 200 basis points or 2% per annum. LIBOR Advantage Loans outstanding shall accrue interest at a per annum rate of 200 basis points, or 2%, above the LIBOR Advantage Rate (the offered rate for delivery in two London Banking Days of deposits of U.S. dollars which the British Bankers' Association fixes as its LIBOR Rate).

The agreement contains covenants which relate to various matters including limitations on further secured indebtedness, consent of RBS for dividends or redemptions or purchases of stock in excess of $500,000 in any fiscal year, investments or advances to or investments in any person (other than currently existing subsidiaries) exceeding $500,000 in any fiscal year, merger or consolidation, limitation on Change of Control (as defined) without the consent of RBS and sales of assets other than in the normal course of business.
