What it is
A cardiac genetic counselor is a healthcare professional with specialized training in genetics and counseling who focuses on inherited heart conditions. They help people understand what genetic information may mean for them and their families. They are not a substitute for a cardiologist, and they don't diagnose conditions on their own.
Their work often centers on family history, the reasons someone might consider genetic heart testing, and what test results can and cannot tell you. Genetic tests show risk or carrier status. They do not diagnose heart disease by themselves, and results need to be read alongside personal and family history, a physical exam, imaging and bloodwork.
Genetic counselors work in many settings, including cardiology clinics, hospitals and independent practices. Licensing and credentialing requirements for genetic counselors vary by state, so it's reasonable to ask any counselor about their training and whether they work with a cardiologist or electrophysiologist.
How it’s traditionally been approached
Traditionally, care for inherited heart conditions has been a team effort. A cardiologist or electrophysiologist evaluates the heart, and a genetic counselor helps with the genetic side of the picture. This includes gathering a detailed family history, often drawn as a family tree, and discussing whether testing may be worth considering.
Counseling has typically happened both before and after testing. Before testing, the conversation often covers what a test can and cannot show, possible result types, and how results might affect relatives. After testing, it often covers what the result means and what questions may be worth bringing back to the cardiologist.
When a disease-causing variant is found, cascade testing is a traditional next step. This means offering testing to biological relatives who may also carry the variant. A negative result doesn't rule out risk, and a variant of uncertain significance is not a diagnosis. Counselors commonly help people understand these distinctions.
How the right cardiologist may help
The right cardiac genetic counselor may help you make sense of a complicated topic in plain language. A first visit is often a conversation. You may be asked about your health, your relatives' heart health, and any history of heart events or sudden loss in the family. It can help to gather what you know ahead of time, and to talk with relatives if you're comfortable doing so.
They may also help you think through the practical side of testing. One example is privacy. In the US, GINA (the Genetic Information Nondiscrimination Act) protects against genetic discrimination in health insurance and employment. It does not cover life, disability or long-term-care insurance, so it's worth asking about those before you test. Coverage for genetic testing also varies by insurer, state and diagnosis, so confirm with your insurer and provider.
Questions you might bring: Is genetic heart testing appropriate for my situation? What could the possible results mean? How might results affect my family? Who will interpret the results with my cardiologist? What happens to my data? A qualified cardiologist, electrophysiologist or counselor can guide you, and no test or visit can promise a particular outcome.
The whole-person view
Your heart, body and mind are connected, and learning about inherited risk can bring up real feelings, such as worry, guilt or relief. Many people feel stress about what results could mean for their children or siblings. Those feelings are common and valid, and they can affect sleep, tension and overall well-being.
Some people find that body-based support, such as the approaches offered through Somatic Experiences, helps them feel more settled while they navigate health uncertainty. Others value talk therapy through Therapists.plus to process difficult news. Every approach has a place, and a counselor can often point you to additional support if you'd like it.

Keep in mind
- Genetic heart testing is educational information here, not medical advice, and results do not diagnose heart disease on their own.
- A negative result does not rule out risk, and a variant of uncertain significance is not a diagnosis. Licensed professionals should guide your care.
- Ask about genetic counseling before and after testing, and about cascade (family) testing if a disease-causing variant is found.
- For emergencies such as chest pain, fainting or trouble breathing, call 911. If you're in emotional crisis, call or text 988.

Frequently asked questions
What does a cardiac genetic counselor do?
A cardiac genetic counselor helps people understand how inherited factors may relate to heart conditions. They review family history, explain what genetic heart testing can and cannot show, and help interpret results alongside your cardiology care. They don't diagnose conditions on their own.
Do I need a referral to see a cardiac genetic counselor?
It depends on the clinic, your insurer and your state. Some practices accept self-referrals, while others ask for a referral from a cardiologist or primary care provider. Ask the counselor's office and your insurer what is required.
Is a cardiac genetic counselor the same as a cardiologist?
No. A cardiologist is a physician who evaluates and manages heart conditions, while a genetic counselor specializes in genetics and counseling. They often work together, and a cardiologist or electrophysiologist generally interprets genetic results with the full clinical picture.
What happens at a genetic counseling visit for heart conditions?
Visits usually involve a conversation about your health and family history, and about whether genetic heart testing may be worth considering. The counselor may explain possible results and the privacy and insurance questions involved. What happens next is a decision made with you and your clinicians.
Does a genetic test diagnose heart disease?
No. Genetic tests show risk or carrier status, and they don't diagnose heart disease on their own. Results must be interpreted with personal and family history, an exam, imaging and bloodwork by a qualified professional. A negative result doesn't rule out risk, and a variant of uncertain significance is not a diagnosis.
Will genetic testing affect my insurance?
In the US, GINA protects against genetic discrimination in health insurance and employment. It does not cover life, disability or long-term-care insurance, so ask about those before testing. Coverage for the testing itself also varies, so confirm with your insurer and provider.
