1. Basis of Presentation (Notes)	9 Months Ended
1. Basis of Presentation (Notes)	Sep. 30, 2014
Basis of presentation [Abstract]
Basis of presentation	Basis of Presentation The consolidated financial statements (the "financial statements") include the accounts of Arrhythmia Research Technology, Inc (“ART”) and its subsidiary, Micron Products, Inc. ("Micron" and together with ART, the “Company”). ART discontinued operations of it’s wholly-owned Pennsylvania subsidiary, RMDDxUSA Corp. (“RMDDxUSA”) and that subsidiary’s Prince Edward Island subsidiary, RMDDx Corporation (“RMDDx” and collectively with RMDDxUSA,“WirelessDx”) in the third quarter of 2012. The WirelessDx results are presented herein as discontinued operations. All intercompany balances and transactions have been eliminated in consolidation. The unaudited interim consolidated financial statements and related notes have been prepared pursuant to the rules and regulations of the Securities and Exchange Commission (the "SEC"). Accordingly, certain information and footnote disclosures normally included in complete financial statements prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") have been omitted pursuant to such rules and regulations. These financial statements and related notes should be read in conjunction with the consolidated financial statements and notes thereto included in the Company's Annual Report on Form 10-K for the year ended December 31, 2013 filed with the SEC on March 21, 2014. Certain reclassifications have been made to prior period amounts to conform to the current year presentation. The results of operations for interim periods are not necessarily indicative of the results to be expected for the full year. The Company's balance sheet at December 31, 2013 has been derived from the audited financial statements at that date, but does not include all the information and footnotes required by GAAP for complete financial statements. The information presented reflects, in the opinion of the management of the Company, all adjustments necessary for a fair presentation of the financial results for the interim periods presented. The preparation of financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the financial statements, and the reported amounts of revenues and expenses during the reporting period. Actual results could differ from those estimates.

Earnings Per Share [Abstract]

Earnings Per Share

Earnings per Share ("EPS")

Basic earnings (loss) per share is computed by dividing net income (loss) available to common shareholders by the weighted average number of common shares outstanding. The computation of diluted earnings (loss) per share is similar to the computation of basic earnings (loss) per share except that the denominator is increased to include the average number of additional common shares that would have been outstanding if the dilutive potential common shares had been issued. In addition, the numerator is adjusted for any changes in net income (loss) that would result from the assumed conversions of those potential shares.

The following table presents the calculation of both basic and diluted EPS.

Intangible Assets, Net [Abstract]

Intangibles

Intangible Assets, Net

The Company assesses the impairment of long-lived assets and intangible assets with finite lives whenever events or changes in circumstances indicate that the carrying value may not be fully recoverable. In the third quarter of 2014, the Company reviewed unamortized patent costs for patents pending. As a result of this review, the Company determined that the patents pending related to the Ambulatory Physiological Monitoring with Remote Analysis were no longer patentable and recorded an impairment charge of $56,237 for the full cost of these patents pending. The impairment charge is included as a component of general and administrative expense on the statement of operations for the three and nine months ended September 30, 2014 and is reflected in the statement of cash flows within depreciation and amortization.

Additionally, in 2014, the Company removed the fully-amortized gross and accumulated amortization balances for the discontinued operations of WirelessDx. Intangible assets consist of the following:



		September 30, 2014						December 31, 2013
	Estimated Useful Life (in years)	Gross		Accumulated Amortization		Net		Gross		Accumulated Amortization		Net
Patents and trademarks	12	$	414,437	$	393,931	$	20,506	$	476,390	$	454,566	$	21,824

Amortization expense, including the $56,237 impairment charge, for the three and nine months ended September 30, 2014 was $57,231 and $66,067, respectively, and was $994 and $122 for the three and nine months ended September 30, 2013. Amortization expense for the nine months ended September 30, 2013 also reflects adjustments to correct year to date accumulated amortization in the second quarter of 2013.

Subordinated promissory notes	$	438,531	$	417,769

The revolving line of credit, equipment line of credit, equipment term loan and the commercial term loan are all under the terms of a multi-year credit facility with a bank entered into on March 29, 2013. The bank facility contains both financial and non-financial covenants.

Revolving line of credit

The revolving line of credit provides for borrowings up to 80% of eligible accounts receivable and 50% of eligible raw materials inventory. The interest rate on the revolver is calculated at the bank's prime rate plus 0.25% (3.50% at September 30, 2014). The revolver has a maturity date of June 2015.

Equipment line of credit and equipment term loan

The equipment line of credit allowed for advances of up to $1.0 million and included a one-year draw period during which payments were interest only. The draw period ended March 29, 2014 and the then outstanding balance on the equipment line of credit of $740,999 was converted to a five-year term loan with a maturity date of March 29, 2019 with monthly payments of $13,890, consisting of principal and interest at a fixed rate of 4.65%.

On June 26, 2014, the Company entered into a new equipment line of credit for $1.0 million under the Company's multi-year credit facility. This equipment line of credit is for the purchase of capital equipment. At September 30, 2014, no amounts had been drawn on the equipment line. The term of this equipment line is six years, maturing on June 26, 2020, inclusive of a maximum one year draw period. Repayment shall consist of monthly interest only payments, equal to the bank's prime rate plus 0.25% as to each advance commencing on the date of the loan through the earlier of: (i) one year from the date of the loan or (ii) the date upon which the equipment line of credit is fully advanced (the “Conversion Date”). On the Conversion Date, principal and interest payments will be due and payable monthly in an amount sufficient to pay the loan in full based upon an amortization schedule commensurate with the remaining term of the loan.

Commercial term loan

The commercial term loan has a five year term with a maturity date in March 2018. The interest rate on the loan is a fixed 4.25% per annum.

Equipment notes

In January 2013, the Company entered into two equipment notes totaling $272,500 with a financing company to acquire production equipment. The notes bear interest at the fixed rate of 4.66% and require monthly payments of principal and interest over a five year term maturing in January 2018.

Subordinated promissory notes

In December 2013, the Company completed a private offering in which the Company sold an aggregate of $500,000 in subordinated promissory notes. The notes are unsecured and require quarterly interest-only payments at a rate of 10% per annum. On the second anniversary following issuance, the interest rate increases to 12% per annum. The notes mature in December 2016 at which point the outstanding balance is due in full. The subordinated promissory notes may be prepaid by the Company at any time following the first anniversary thereof without penalty. The notes are subordinated to all indebtedness of the Company pursuant to the bank credit facility.

In connection with the subordinated promissory notes, the Company issued warrants to purchase the Company's common stock at $3.51 per share. The warrants expire in December 2016. The proceeds were allocated between the notes and warrants on a relative fair value basis resulting in $416,950 allocated to the notes and $83,050 allocated to the warrants as part of Additional-Paid-in-Capital. The total discount on the notes is being recognized as non-cash interest expense over the term of the notes. For the three and nine months ended September 30, 2014, the Company recorded $6,920 and 20,762 of non-cash interest expense, respectively, related to the amortization of the discount. The unamortized discount which is net against the outstanding balance of the subordinated promissory notes is $61,469 at September 30, 2014 and $82,231 at December 31, 2013.

7. Income Taxes	9 Months Ended
7. Income Taxes	Sep. 30, 2014
Income Taxes [Abstract]
Income Taxes	Income Taxes The tax provisions for the three and nine months ended September 30, 2014 and 2013 are attributable to the U.S. Federal, state and foreign income taxes on our continuing operations. No provision was recorded for the three months ended September 30, 2014, as such amounts were determined to be negligible because of the Company’s ability to offset the taxable income with loss carryforwards and the reversal of portions of the valuation allowance on deferred tax assets. The tax provision for the nine months ended September 30, 2013 also includes the impact on tax expense of $2,267,969 associated with the establishment of a full valuation allowance of the Company’s beginning of the year deferred tax assets. The Company has a full valuation allowance against its deferred tax assets at September 30, 2014 and December 31, 2013. Management expects to reevaluate the allowance on its deferred tax assets at December 31, 2014. The Company has federal, state and foreign net operating loss carryforwards totaling $7,420,000, $10,471,000 and $1,039,000 respectively, which begin to expire in 2030. The Company also had federal and state tax credit carryovers of $243,000 and $281,000, respectively. The federal and state tax credits begin to expire in 2026 and 2014, respectively.

- Definition

The entire disclosure for income taxes.

At December 31, 2013, the Company had a $1.0 million liability for an unmet performance obligation related to the discontinued operations. This performance obligation was secured by $1.0 million of restricted cash. The performance guarantee liability was carried on the balance sheet of continuing operations, as the liability was guaranteed by ART.

In May 2014, $975,430 was drawn from the restricted cash, satisfying the guarantee on the performance obligation. The balance of $24,570 was returned to ART and recorded as other income on the condensed consolidated statements of operations.

The assets and liabilities of the discontinued operations are listed below:
