Wolff-Parkinson-White (WPW) syndrome is a congenital heart condition causing the heart to beat abnormally fast for periods of time.
It is not as rare as many might think and affects between one and three in every 1,000 people.
What is the cause of Wolff-Parkinson-White (WPW) syndrome?
There is an extra electrical connection in the heart and is usually present at birth. Despite the fact that it is comgenital the symptoms may not develop until later in life.
Quite often such cases are diagnosed in otherwise healthy adults aged between 20 and 40. This extra electrical connection might not cause any symptoms and sudenly picked up in an electrocardiogram (ECG) test that had been carried out for completely different reason.
Further tests will need be carried to determine if or what treatment is required.
Patientsl experience episodes where their heart suddenly begins to race, before suddenly stopping or slowing down abruptly. This rapid heart rate condition is called supraventricular tachycardia (SVT).
