EXPLANATORY NOTE





Hypertension Diagnostics, Inc. (the company) is filing this amendment (the Form 10-Q/A) to our Quarterly Report on Form 10-Q for the quarter ended December 31, 2009 (the Form 10-Q), filed with the U.S. Securities and Exchange Commission on March 25, 2010, solely to correct an error on the certifications contained in Exhibit 31.1. Pursuant to Item 601(b)(31) Regulation S-X, the certifications did not contain the required introductory language in paragraph 4 of the certification that refers to the certifying officers’ responsibility for establishing and maintaining internal control over financial reporting for the company and also did not include paragraph 4(b) which refers to the design of the company’s internal control over financial reporting.





The certifications of this Form 10-Q/A correctly include the required introductory language in paragraph 4 of the certification that refers to the certifying officers’ responsibility for establishing and maintaining internal control over financial reporting for the company and now includes the language as prescribed in paragraph 4(b) which refers to the design of the company’s internal control over financial reporting.  This Form 10-Q/A should be read in conjunction with the original Form 10-Q, which continues to speak as of the date of the Form 10-Q. Except as specifically noted above, this Form 10-Q/A does not modify or update disclosures in the original Form 10-Q. Accordingly, this Form 10-Q/A does not reflect events occurring after the filing of the Form 10-Q or modify or update any related or other disclosures.
