Dear , This is in reference to your application for correction of your naval record pursuant to Title 10, United States Code, Section 1552. After careful and conscientious consideration of relevant portions of your naval record and your application, the Board for Correction of Naval Records (Board) found the evidence submitted was insufficient to establish the existence of probable material error or injustice. Consequently, your application has been denied. Although your application was not filed in a timely manner, the Board found it in the interest of justice to waive the statute of limitations and consider your case on its merits. A three-member panel of the Board, sitting in executive session, considered your application on 22 October 2020. The names and votes of the members of the panel will be furnished upon request. Your allegations of error and injustice were reviewed in accordance with administrative regulations and procedures applicable to the proceedings of this Board. Documentary material considered by the Board consisted of your application, together with all material submitted in support thereof, relevant portions of your naval record and applicable statutes, regulations and policies. A review of your record shows that you entered active duty with the Marine Corps on 6 April 1987. Within 10 days of commencing training, you reported symptoms of dizziness and heart palpitations. An electrocardiogram determined you suffered from a low heart rate and you reported a three year history of fainting spells. As a result, a medical board diagnosed you with preexisting Bradycardia Secondary to Hypervagal Tone and recommended you for administrative separation. On 15 May 1987, you were discharged for a disability condition that existed prior to entry with an uncharacterized entry level separation. The Board carefully considered your arguments that you deserve a disability discharge. You assert that you had no history of the disability condition prior to entering the Marine Corps and submitted evidence of preservice physical activities. Unfortunately, the Board did not agree with your rationale for relief. In reviewing your record, the Board concluded the preponderance of the evidence supports the medical board findings in your case. Your medical history of preservice fainting spells was documented as being provided by you. The Board found no evidence this medical history was erroneous or fabricated by the medical board. While the Board considered your history of physical activities prior to entering the Marine Corps, the Board found the medical board report credible. After weighing the evidence, the Board determined the evidence of your preservice activities did not preclude a finding that you performed those activities with your Bradycardia condition. As documented in the medical board report, you had a three-year history of fainting spells that was apparently intermittent and would have allowed you to participate in physical activities prior to entering the Marine Corps. Accordingly, the Board found insufficient evidence of error or injustice to warrant a change to your record. Regarding your request for a personal appearance, the Board determined that a personal appearance with or without counsel will not materially add to their understanding of the issues involved. Therefore, the Board determined that a personal appearance was not necessary and considered your case based on the evidence of record. It is regretted that the circumstances of your case are such that favorable action cannot be taken. You are entitled to have the Board reconsider its decision upon submission of new matters, which will require you to complete and submit a new DD Form 149. New matters are those not previously presented to or considered by the Board. In this regard, it is important to keep in mind that a presumption of regularity attaches to all official records. Consequently, when applying for a correction of an official naval record, the burden is on the applicant to demonstrate the existence of probable material error or injustice. Sincerely,
