STOCKHOLDER EQUITY (Details) [Line Items]                              
Preferred Stock, Dividend Payment Terms   declared a dividend of one preferred share purchase right for each outstanding share of BioSig’s common stock to stockholders of record on July 27, 2020, and one right will be issued for each new share of common stock issued thereafter. Each right will initially trade with common stock, and will allow its holder to purchase from BioSig one one-thousandth of a share of Series F Junior Participating Preferred stock                          
Preferred Stock, Par or Stated Value Per Share (in Dollars per share)   $ 0.001         $ 0.001     $ 0.001   $ 0.001   $ 0.001 $ 0.001
Preferred Stock, Redemption Price Per Share (in Dollars per share)   $ 50.00                          
Preferred Stock, Voting Rights   In the event that a person or group acquires beneficial ownership of 12% or more of BioSig’s then outstanding common stock, subject to certain exceptions, each right would entitle its holder (other than such person or members of such group) to purchase additional shares of BioSig’s common stock having a market value of two times the exercise price of the right. In addition, at any time after a person or group acquires 12% or more of BioSig’s outstanding common stock (unless such person or group acquires 50% or more), the Board may exchange one share of BioSig’s common stock for each outstanding right (other than rights owned by such person or group, which would have become void). The Rights Plan could make it more difficult for a third party to acquire control of BioSig or a large block of our common stock without the approval of our board of directors. The rights will expire on July 13, 2021, unless terminated earlier by our board of directors.

Preferred Stock, Redemption Terms                       The Series C Preferred Stock contains triggering events which would, among other things, require redemption (i) in cash, at the greater of (a) 120% of the stated value of $1,000 or (b) the product of (I) the variable weighted average price of our common stock on the trading day immediately preceding the date of the triggering event and (II) the stated value divided by the then conversion price or (ii) in shares of our common stock, equal to a number of shares equal to the amount set forth in (i) above divided by 75%. As of September 30, 2020, the aggregate stated value of our Series C Preferred Stock was $105,000. The triggering events include our being subject to a judgment of greater than $100,000 or our initiation of bankruptcy proceedings. If any of the triggering events contained in our Series C Preferred Stock occur, the holders of our Series C Preferred Stock may demand redemption, an obligation the Company may not have the ability to meet at the time of such demand.  The Company will be required to pay interest on any amounts remaining unpaid after the required redemption of our Series C Preferred Stock, at a rate equal to the lesser of 18% per annum or the maximum rate permitted by applicable law. Accordingly, the Company has classified the Series C Preferred Stock as a mezzanine obligation in the accompanying consolidated balance sheets.
