Inherited cardiac conditions

Diagnose genetic heart disorders

Some heart conditions are passed down through the parents’ genes to their children. There are a number of heart diseases that can be passed on genetically through a faulty or mutated gene.

Some of these conditions can be life-threatening. Inherited cardiac conditions (ICCs) can be hard to spot, as they do not always present with symptoms. It can be helpful to draw up a family tree of conditions with a specialist who can help you to understand any risks.


The main symptoms of some ICCs that you should be aware of are:

  • Palpitations (where you can feel your own heartbeat strongly)
  • Fainting or blackouts (syncope)

If you experience either of these symptoms regularly, it is important that you make an appointment with a cardiologist to check your heart health and understand any potentially underlying conditions.

Common inherited heart conditions

Some of the most common inherited heart conditions include:

  • Hypertrophic cardiomyopathy (HCM), idiopathic or familial dilated cardiomyopathy (DCM)
  • Arrhythmogenic right ventricular cardiomyopathy (ARVC)
  • Left ventricular non-compaction cardiomyopathy
  • Restrictive cardiomyopathy

All of these conditions can lead to heart failure. There are also a number of arrhythmias that can be passed on genetically, including Long QT syndrome (LQTS), Brugada syndrome, Catecholaminergic Polymorphic Ventricular Tachycardia (CPVT), and Short QT Syndrome (SQTS).

A cardiologist can help you to diagnose, treat, and manage any of these inherited conditions which can affect the muscles and rhythm of the heart.

What to do next

If you are concerned about your family’s history of heart disease, or if you are experiencing any heart-related symptoms, do not hesitate to speak to one of our specialists.

A close family member has a cardiac condition, but I am fit and well. Should I get checked out?

Some heart disease does not present with symptoms. You can feel well, but still have an underlying condition. It is always best to get evaluated by a specialist if you have a strong family history of heart disease, as the more you know about the risks, the more you can reduce them.

What are the main symptoms of inherited cardiac conditions (ICC)?

The main symptoms of an ICC can be subtle, such as palpitations, or more noticeable, such as fainting, or blacking out.

Why is it important to check for an ICC?

Although the symptoms may not always be severe, or even noticeable, ICCs can be life-threatening as they can cause heart failure. The more information you can get about any potential conditions will help you to stay healthier in the long run.
