Paediatric heart rhythm disorders

It is well known that heart rhythm disorders (arrhythmias) occur in adults, but few are aware that it is also a significant problem among many South African children. Children may be born with a heart disorder that causes electrical and functional problems in the heart. In some cases, parents may not realise their child has a debilitating heart disorder until it is diagnosed by a paediatric cardiologist.

Symptoms of paediatric heart rhythm disorders

Fainting can be an indication that your child is suffering from a heart rhythm disorder. You should always seek medical attention if your child faints. Other symptoms may include heart palpitations, dizziness, light headedness, discomfort in the chest, or general weakness. A child with an inherited heart rhythm disorder may fail to thrive.

Causes of paediatric heart rhythm disorders

Heart damage and rhythm disorders may be caused by several factors including certain infections and rheumatic heart disease. However heart rhythm problems are particularly common among babies born with a complex congenital, or inherited, heart defect.

Treatment of paediatric heart rhythm disorders

In addition to conservative treatments such as medication, paediatric cardiologists offer a range of services for the diagnosis and treatment of heart rhythm disorders. These include electrophysiology studies and minimally invasive catheter based ablation procedures to correct certain heart rhythm problems.

Cardiologists who have specialised in electrophysiology for adults can also treat children with rhythm disorders through interventions such as cardiac ablations to correct abnormalities and restore a coordinated, regular heartbeat.
