VA Disability Rating for Sick Sinus Syndrome: Codes, METs, and TDIU

The VA disability rating for sick sinus syndrome ranges from 10% to 100%, assigned under whichever cardiac diagnostic code best matches the veteran’s predominant symptoms. There is no standalone code for the condition itself. Instead, the VA uses Diagnostic Code 7010 when fast rhythms (supraventricular tachycardia) dominate, Diagnostic Code 7009 when symptomatic bradycardia requiring a pacemaker dominates, and Diagnostic Code 7018 in the month following a pacemaker implantation. The percentage depends on how often the veteran needs treatment for episodes, whether a pacemaker has been implanted, and how much physical exertion the veteran can tolerate before cardiac symptoms appear.1Cornell Law Institute. 38 CFR § 4.104 – Schedule of Ratings, Cardiovascular System

Which Diagnostic Code Applies

Sick sinus syndrome can produce fast rhythms, slow rhythms, or both alternating (tachy-brady). Because more than one arrhythmia code could fit, the regulation directs the VA to assign a single evaluation under the code that reflects the “predominant disability picture.”1Cornell Law Institute. 38 CFR § 4.104 – Schedule of Ratings, Cardiovascular System

DC 7010 — Supraventricular Tachycardia

When the fast-rhythm side of the condition is predominant (paroxysmal atrial fibrillation, atrial flutter, or other supraventricular tachycardia), the VA rates under DC 7010. The current criteria are:

  • 30%: confirmed by ECG, with five or more treatment interventions per year.
  • 10%: confirmed by ECG, with one to four treatment interventions per year; or confirmed by ECG with continuous oral medication or vagal maneuvers used to control the condition.

A “treatment intervention” means an instance where a symptomatic patient requires intravenous pharmacologic adjustment, cardioversion, or ablation for symptom relief.2GovInfo. 38 CFR § 4.104 – Diseases of the Heart The older “episodes per year” standard that appears in some earlier Board decisions has been replaced by this treatment-intervention language.

DC 7009 — Bradycardia Requiring a Pacemaker

When the slow-rhythm side dominates and the veteran needs a permanent pacemaker, DC 7009 applies. Sinus bradycardia is explicitly listed among the bradyarrhythmias covered. Asymptomatic bradycardia is a medical finding only, not a compensable disability; the bradycardia must be symptomatic and must require permanent pacemaker implantation to qualify.1Cornell Law Institute. 38 CFR § 4.104 – Schedule of Ratings, Cardiovascular System Once the pacemaker is in, the rating shifts to the DC 7018 framework.

DC 7018 — Implantable Cardiac Pacemakers

A pacemaker implantation or re-implantation earns a temporary 100% rating for one month after hospital discharge. After that month, the VA re-evaluates the condition under DC 7010, DC 7011 (ventricular arrhythmias), or DC 7015 (atrioventricular block), depending on residual symptoms. The minimum permanent rating for a veteran with an implanted pacemaker is 10%.2GovInfo. 38 CFR § 4.104 – Diseases of the Heart

How METs Drive the Higher Ratings

Once the case runs under the General Rating Formula for Heart Diseases (which applies after pacemaker implantation and to several other cardiac codes), the percentage is set by metabolic equivalents, or METs. One MET equals the energy cost of standing quietly at rest. The examiner identifies the workload at which the veteran begins to experience cardiac symptoms such as breathlessness, fatigue, angina, dizziness, or syncope:1Cornell Law Institute. 38 CFR § 4.104 – Schedule of Ratings, Cardiovascular System

  • 100%: symptoms at a workload of 3.0 METs or less.
  • 60%: symptoms at 3.1 to 5.0 METs.
  • 30%: symptoms at 5.1 to 7.0 METs, or evidence of cardiac hypertrophy or dilatation on echocardiogram or equivalent imaging.
  • 10%: symptoms at 7.1 to 10.0 METs, or continuous medication required for control.

A veteran who can jog before symptoms appear will rate lower than one who gets winded crossing a room.

If exercise stress testing is medically unsafe, the VA allows an interview-based METs estimate. The examiner asks about daily activities (walking a block, climbing stairs, household tasks) and assigns a METs level from those answers.3Department of Veterans Affairs. Heart Conditions Disability Benefits Questionnaire One caveat: the METs limitation must be attributable to the heart condition. A low result caused by an unrelated problem like back pain cannot be used to justify a higher cardiac rating.4Department of Veterans Affairs. BVA Decision, Citation Nr 22002979

Left ventricular ejection fraction is no longer a factor. Older Board decisions and secondary sources still cite LVEF thresholds, but a correcting amendment published in November 2021 removed LVEF from the General Rating Formula. Current ratings turn on METs and associated symptoms, not ejection fraction percentages.5Federal Register. Schedule for Rating Disabilities; The Cardiovascular System (Correction)

What Each Rating Pays

Monthly VA disability compensation rates as of December 1, 2025, for veterans without dependents:6Department of Veterans Affairs. VA Disability Compensation Rates

  • 10%: $180.42
  • 30%: $552.47
  • 60%: $1,435.02
  • 100%: $3,938.58

Veterans with dependents receive higher amounts, and the rates are adjusted annually for cost of living.

Getting Service Connection First

A rating percentage only matters after the VA agrees the condition is connected to military service. Two paths are available.

Direct Service Connection

The veteran shows that the condition was caused or aggravated by service, typically through evidence that symptoms began during active duty or that an in-service event led to its development. Where service treatment records are incomplete, credible lay evidence of symptoms during service, combined with a medical nexus opinion, can carry a claim. In one Board decision, the veteran was granted service connection for sick sinus syndrome despite missing service treatment records, based on a credible account of in-service symptoms and a medical examiner’s opinion that it was “more likely than not” the condition first manifested during active duty.7Department of Veterans Affairs. BVA Decision, Citation Nr 1526133

Secondary Service Connection

The veteran can also claim sick sinus syndrome as secondary to an already service-connected condition. Under 38 C.F.R. § 3.310(b), the claim must show that the service-connected condition either caused the sick sinus syndrome or aggravated it beyond its natural progression. These claims are not easy to win. In one 2020 decision, a veteran’s claim that his sick sinus syndrome was secondary to diabetes, hypertension, and coronary artery disease was denied after the examiner concluded that sinus node fibrosis (an age-related process) is the most common cause and found no evidence of aggravation.8Department of Veterans Affairs. BVA Decision, Citation Nr 20071046 In another case, the Board remanded for a new examination to address whether chronic hyperinsulinemia from diabetes could cause sinus node dysfunction, showing the kind of specific medical reasoning these claims require.9Department of Veterans Affairs. BVA Decision, Citation Nr 1807796

Agent Orange Does Not Cover It

Ischemic heart disease is a presumptive condition for veterans exposed to Agent Orange. Sick sinus syndrome is not. The Board has expressly ruled that sick sinus syndrome “is not a heart condition that qualifies within the generally accepted medical definition of ischemic heart disease” and so cannot be service-connected on a presumptive basis due to herbicide exposure.10Department of Veterans Affairs. BVA Decision, Citation Nr 21009861 A veteran with herbicide exposure who develops sick sinus syndrome would need to pursue direct service connection or secondary connection through an already service-connected condition.

Evidence That Moves the Rating

Heart claims are evaluated through a Disability Benefits Questionnaire completed by a healthcare provider, either at a Compensation and Pension examination or by the veteran’s own doctor. The items that most directly affect the rating percentage are:3Department of Veterans Affairs. Heart Conditions Disability Benefits Questionnaire

  • ECG and Holter monitor results documenting the type and frequency of rhythm disturbances, which drives DC 7010.
  • METs test results from either exercise or interview-based estimation.
  • Imaging showing cardiac hypertrophy or dilatation, which can support a 30% rating under the General Rating Formula even when METs alone would not.
  • Pacemaker implantation dates, device interrogation data, and hospital discharge records.
  • A current list of continuous cardiac medications, which supports the 10% minimum.
  • A nexus letter tying the condition to service, particularly for direct or secondary claims.
  • A personal statement describing how symptoms affect work and daily life.

Objective documentation matters. A veteran’s own report of symptoms is considered competent lay evidence, but it is generally insufficient on its own to establish the clinical frequency the schedule requires; ECG or Holter records are what substantiate arrhythmia episodes.

Why You Can’t Stack Arrhythmia Ratings

Sick sinus syndrome frequently coexists with atrial fibrillation, and some veterans want to know whether each earns its own rating. Under 38 C.F.R. § 4.14, the VA’s anti-pyramiding rule bars rating the same symptoms under multiple diagnostic codes.11eCFR. 38 CFR Part 4 – Schedule for Rating Disabilities For arrhythmia-related conditions (sick sinus syndrome, atrial fibrillation, atrioventricular block, tachycardia), the VA assigns a single evaluation under whichever code produces the highest rating or best reflects the predominant disability.1Cornell Law Institute. 38 CFR § 4.104 – Schedule of Ratings, Cardiovascular System

A sick sinus syndrome rating does combine with ratings for unrelated, non-cardiac disabilities. The VA uses a “whole person” method: ratings are ordered high to low, each successive rating applies to the remaining non-disabled percentage rather than adding straight across, and the final combined value is rounded to the nearest 10%.12Department of Veterans Affairs.

Reaching 100% Pay Through TDIU

Because DC 7010 caps at 30% and pacemaker cases often settle around 10% to 30% after the temporary 100% month ends, veterans whose sick sinus syndrome severely limits their ability to work sometimes reach the 100% pay rate through Total Disability based on Individual Unemployability. Schedular TDIU requires either a single disability rated at 60% or higher, or a combined rating of 70% or more with at least one condition rated at 40% or above. Veterans who fall short of those thresholds can still apply for extraschedular TDIU, which the Director of Compensation Services reviews case by case.13Chisholm Chisholm & Kilpatrick.
