Inherited heart conditions and coronavirus (COVID-19)

Brugada syndrome

Detecting and treating fever is important for patients with Brugada syndrome.

Follow the government's advice regarding social distancing and self-isolation.

A temperature higher than 38°C is a fever and should be treated using paracetamol or ibuprofen. If you have a high fever (40°C or higher) which does not come down after treating it, and if you do not have an implantable cardioverter-defibrillator (ICD), please go to your local emergency department for an electrocardiogram (ECG). You may need to be admitted for cardiac monitoring.

If you have Brugada syndrome, continue to follow the usual advice we give:

Long QT syndrome

Please follow our usual advice if you have:

  • long QT syndrome
  • a prolonged QT on your electrocardiogram (ECG) even when a definite diagnosis of an inherited condition has not been made

It is important to continue beta-blocker medicines if these have been prescribed by your doctor. Avoid medicines that can cause QT prolongation. Treat diarrhoea and vomiting promptly (for example with Dioralyte) to avoid low potassium levels.

Fever does not generally seem to cause a problem in long QT syndrome (but a possible exception is patients with long QT syndrome type 2). These patients should take paracetamol to reduce a fever (or antibiotics if appropriate for a bacterial infection).


We aim to improve the diagnosis, treatment and outcome of patients with inherited heart disease. We provide:

  • diagnosis
  • high-quality care
  • psychological support for you and your family

We offer clinics at Guy's and St Thomas' and King's College Hospitals. These clinics combine clinical, familial and genetic assessment. We aim to minimise the number of visits you make to hospital.

We work closely with our children's heart services team at Evelina London to provide a smooth transition of care from childhood, to adolescence through to adulthood.

Inherited cardiac conditions are family disorders that can affect the heart muscle and the heart rhythm. Our team of doctors and other healthcare professionals provide treatment and support for a range of conditions.

Inherited heart muscle conditions are also known as cardiomyopathies. These can lead to heart failure.

They include:

Inherited heart rhythm conditions are also known as inherited arrhythmia syndromes. These conditions can cause problems with the heart rate and rhythm.

They include:

Other conditions we see include:

  • muscular dystrophies associated with heart involvement:
    • myotonic dystrophy
    • limb girdle muscular dystrophy
    • Emery-Dreifuss muscular dystrophy
    • Becker muscular dystrophy
    • Duchenne muscular dystrophy
  • inherited aortopathies

  • inherited metabolic disease with heart involvement such as mitochondrial disorders and Anderson-Fabry disease

We have access to a number of tests for the heart and genetic tests.

Research and clinical trials

We are part of King's Health Partners Academic Health Sciences Centre. This brings together research, clinical excellence and world-class teaching to deliver advances in healthcare.
