| 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 its 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. In May 2014, RMDDxUSA filed for bankruptcy and the Chapter 7 discharge order was issued on March 20, 2015 and the case was closed (see Note 10). 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, 2014 filed with the SEC on March 20, 2015. 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, 2014 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 | 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:

| Debt [Abstract] | |||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||||
| Debt | Debt The following table sets forth the items which comprise debt for the Company:
Bank Debt The revolving line of credit (the "revolver"), commercial term loan, two equipment term loans and an equipment line of credit are all under the terms of a multi-year credit facility with a bank as detailed below. The bank facility contains both financial and non-financial covenants, all of which the Company is in compliance with at June 30, 2015. Revolver The revolver 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 June 30, 2015). The original maturity date of the revolver was June 30, 2015, therefore, as of December 31, 2014 the balance of the revolver was classified as a current liability. In June 2015, the revolver was extended for an additional two-year period maturing June 30, 2017 and is therefore classified as a long-term liability on the Company's balance sheet at June 30, 2015. 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, and requires monthly payments of approximately $28,000. Equipment line of credit and equipment term loans The original 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 an equipment term loan with a five-year term, maturing on of March 29, 2019. The equipment term loan requires monthly payments of approximately $14,000, consisting of principal and interest at a fixed rate of 4.65%. On June 26, 2014, the Company entered into an equipment line of credit that 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 June 26, 2015 and the then outstanding balance on the equipment line of credit of $415,785 was converted to an equipment term loan with a five-year term, maturing on of June 26, 2020. The equipment term loan requires monthly payments of approximately $8,000, consisting of principal and interest at a fixed rate of 4.67%. On June 19, 2015, the Company entered into a new equipment line of credit for $1.0 million under the Company's multi-year credit facility. At June 30, 2015, no amounts had been drawn on the new equipment line of credit. The term of this equipment line of credit is six years, maturing on June 19, 2021, 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. Other Debt 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 of approximately $5,000 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 six months ended June 30, 2015 and 2014, the Company recorded $6,921 and $13,842, respectively, of non-cash interest expense related to the amortization of the discount. The unamortized discount which is net against the outstanding balance of the subordinated promissory notes is $40,706 at June 30, 2015 and $54,548 at December 31, 2014. |
