Wolff-Parkinson-White syndrome (WPW) is a heart condition characterized by an extra electrical pathway between the heart's upper and lower chambers. This abnormal pathway can lead to episodes of rapid heart rate, known as tachycardia. Symptoms may include palpitations, dizziness, or fainting, but some individuals may not experience any noticeable symptoms. Diagnosis typically involves an electrocardiogram (ECG), which can reveal the characteristic patterns associated with WPW. Treatment options may include medications, lifestyle changes, or procedures like catheter ablation to eliminate the extra pathway, helping to restore a normal heart rhythm.
