Arrhythmia Research Technology, Inc. Announces Delay in Finalizing Fourth Quarter and 2011 Year End Results

FITCHBURG, MA--(Marketwire - April 17, 2012) - Arrhythmia Research Technology, Inc. (NYSE Amex: HRT) (the "Company") reported today that it was unable to file its annual report on Form 10-K for the fiscal year ended December 31, 2011 within the automatic extension of its due date to April 16, 2012 afforded by its filing of a Form 12b-25 Notification of Late Filing with the Securities and Exchange Commission.

The delay in filing is due to an ongoing internal review by the Audit Committee and auditors relating to the adjustments to the calculation of the tax deferred assets in the Company's Canadian subsidiary, RMDDx Corporation, for the fiscal year ended December 31, 2011.

As of today's date, the audit is not complete. However, for the year ended December 31, 2011, the Company preliminarily expects to report the following:

                                 Preliminary   
                                 12/31/2011    
                              ---------------- 
Consolidated Revenues         $     24,256,373 
Net Loss                            (1,709,672)
Total Assets                        19,249,230 
Total Liabilities                    3,768,994 
Total Stockholders' Equity          15,480,236 

Consequently, the Company is unable to determine with reasonable certainty at this time the significance of any such adjustments and their effect on the net loss and total liabilities and stockholders' equity. Management is working diligently with its Audit Committee, the Audit Committee's outside experts and the Company's independent auditor to determine whether any potential adjustments are required and the extent thereof. The Company expects to finalize the 10-K by April 27, 2012. However, until the review is complete and a final determination is made, the Company cannot provide further assurance regarding the results of operations for the affected periods or whether adjustments will be required.

James E. Rouse, the Company's President and Chief Executive Officer, stated "We want our stockholders to know that it is of paramount importance to us to provide confidence and transparency in our financial statements and that we are doing everything possible to ensure that this a one-time only event."
