wpw syndrome symptoms
People with WPW are usually asymptomatic. However, the individual may experience palpitations, dizziness, shortness of breath, or syncope (fainting or near fainting) during episodes of supraventricular tachycardia. The telltale delta wave may sometimesâbut not alwaysâbe seen on an electrocardiogram (ECG/EKG).
WolffâParkinsonâWhite syndrome (WPW) is one of several disorders of the electrical system of the heart that are commonly referred to as pre-excitation syndromes. WPW is caused by the presence of an abnormal accessory electrical conduction pathway between the atria and the ventricles.
