A few words of thanks would be greatly appreciated.

Wolff-Parkinson-White syndrome - Definition


Wolff-Parkinson-White syndrome is a cardiological disorder. It manifests as paroxysmal supraventricular tachycardia episodes where the heart rate suddenly quickens. This syndrome is secondary to an abnormality in the conduction of electrical impulses, with an abnormal conduction pathway. It can be serious and lead to more worrying heart problems, such as atrial fibrillation or even ventricular fibrillation. Diagnosis is established using heart monitor, such as an electrocardiogram or ECG, which reveals an abnormal wave called a delta wave, characteristic of this syndrome. Other more specific tests are also available in order to determine whether medicinal treatment using anti-arrhythmic drugs will suffice, or if the conduction pathway must be ablated using radiofrequency.
