Basis of Presentation	Sep. 30, 2016
Basis of Presentation [Abstract]
Basis of Presentation	1. 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 condensed 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, 2015 filed with the SEC on March 10, 2016. 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, 2015 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 (_EPS_)

Earnings per Share ("EPS")	Sep. 30, 2016
Earnings per Share ("EPS") [Abstract]
Earnings per Share ("EPS")	2. 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. For the three and nine months ended September 30, 2016 and 2015 all shares are anti-dilutive. For this reason the EPS table has been removed.

On December 4, 2015, the Company entered into a Letter of Intent to sell its two unoccupied buildings, with a total of approximately 52,000 square feet, and land, at its Fitchburg, Massachusetts campus. On January 13, 2016, the Company entered into a Purchase and Sale Agreement to sell these two buildings which have been classified as Assets Held for Sale at September 30, 2016 and December 31, 2015. The carrying value of the properties ($665,000) approximated the fair value less the cost to sell. The Company originally expected the sale of the properties to be completed by the end of 2016; however, due to ongoing renegotiations, the Company now expects the sale to occur by the end of 2017. The Company does not expect any material impact on the statement of operations.

Bank Debt

The revolving line of credit (the "revolver"), equipment line of credit, commercial term loan, and three equipment term loans are all under the terms of a multi-year credit facility with a bank as detailed below. The debt is secured by substantially all assets of the Company with the exception of real property.

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% (3.75% at September 30, 2016). The revolver has a maturity date of June 2017. Amounts available to borrow under the revolver are $398,528 at September 30, 2016.

Commercial term loan

The commercial term loan has a five year term with a maturity date in March 2018. The commercial loan requires monthly payments of approximately $28,000, consisting of principal and interest at a fixed rate of 4.25%.

Equipment line of credit and equipment term loans

On March 29, 2013, 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 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 as 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 as 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 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 20, 2016 and the then outstanding balance on the equipment line of credit of $881,701 was converted to an equipment term loan with a five-year term, maturing as of June 19, 2021. The equipment term loan requires monthly payments of approximately $17,000, consisting of principal and interest at a fixed rate of 4.68%.

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 for the first two years, increasing to 12% per annum in December 2015. 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. The Company recorded $6,921 and $20,763 for the three and nine months ended September 30, 2016 and 2015 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 $6,102 at September 30, 2016 and $26,865 at December 31, 2015.

In October 2016, certain of these promissory notes and the unexercised warrants were amended to extend their maturity dates to December 2018 (Note 11).

Six of the seven investors agreed to extend the maturity dates of their respective Notes, in the aggregate amount of $450,000, from December 18, 2016 to December 31, 2018. Additionally, the December 18, 2016 expiration date of the 70,000 unexercised Warrants was also extended to December 31, 2018. The terms of the $50,000 Note of the investor electing not to extend remains unchanged and remains payable on December 18, 2016. This investor has no unexercised Warrants. The extended Notes will bear interest on the unpaid principal at a simple annual interest rate equal to 10% per annum during the extension period, December 19, 2016 to December 31, 2018. Interest only shall be payable in cash on a quarterly basis. Each investor entered into a Subordination Agreement with the initial offering which remains in effect throughout the extension period. The Subordination Agreements provide that the indebtedness pursuant to the Notes shall be subordinated to all indebtedness of the Company pursuant to its multi-year credit facility with a Massachusetts based bank. The initial offering provided that for every $50,000 in principal amount of Note, each investor received a Warrant to purchase 10,000 shares of common stock. The Warrants as amended are exercisable during the period commencing six months after issuance and for five years from issuance, at an exercise price equal to $3.51 per share, namely, the closing market price of the Company’s common stock on the day prior to the closing date of the offering. The Company calculated the incremental fair value of extending the expiration date of the Notes and Warrants and determined that the amendment represented a debt modification in accordance the guidance outlined in ASC-470, “Debt”. Using the Black-Scholes model, and the 10% test, the Company determined that the incremental fair value of the warrants to be $15,818, which will be recorded as a discount against the Notes Payable and an increase in Additional Paid-in Capital. Bank debt In October 2016, the Company received a commitment letter from its Massachusetts based bank which outlines proposed terms to refinance the Company’s term debt subject to the terms and conditions and assumptions outlined therein. The proposed terms include consolidating the Company’s outstanding commercial term loan, three equipment term loans and $500,000 from the revolver to create a single term note of approximately $2.6 million. In addition the proposal includes a new $1.0 million equipment line of credit and a $500,000 revolver over-advance feature which is contingent upon approval of a working capital guarantee program through the Massachusetts economic development and finance agency. The over-advance feature will provide guarantees to the bank on advances on accounts receivable aged between 90 and 180 days. Some of the Company’s off-shore product deliveries take weeks to arrive at foreign ports and the related credit terms are extended accordingly. The over-advance feature is beneficial to the Company because it adds these type of accounts to the Company’s borrowing base. The proposed agreement is expected to contain both financial and non-financial covenants that are substantially the same as the existing bank agreement. The Company expects to close on the new agreement in the fourth quarter of 2016.
