Pre-excitation syndrome or Wolff-Parkinson-White syndrome (WPW) occurs when the electrical impulse in the heart spreads directly from the atria to the ventricles, bypassing the AV node and the Hiss bundle, and through the accessory bundle. This can cause serious arrhythmias.
This disease is often asymptomatic and is recognized only on the basis ofEKG . The most common symptoms arepalpitations- i.e. fast or irregular beatsheartscaused byarrhythmias- atrial tachycardia or fibrillation . In addition to palpitations, arrhythmia can also cause weakness, shortness of breath, chest pain, fainting and unconsciousness.
Pre-excitation syndrome - diagnosis
WPW syndrome is diagnosed on an ECG. Additionally, it is possible to perform ECHO, Holter and electrophysiological examination of the heart.
Pre-excitation syndrome - treatment
Surgical treatment is recommended, during which an ablation procedure is performed, which consists in cutting an additional bundle (Kent's bundle). Propranolol is administered to prevent tachycardia. In the treatment of chronic disease, in addition to ablation, amiodarone or propafenone can be used. In this condition, it is very important to eat properly to maintain normal cholesterol, sugar and blood pressure levels.
ImportantPre-excitation syndrome can cause ECG changes that mimic a heart attack. Therefore, you should always have ECG records with you and, in case of medical intervention, provide documents confirming the diagnosis of this disease. Doing so can prevent unnecessary hospitalization due to suspected heart attack.
