Pre Excitation Syndrome, also known as Wolff-Parkinson-White syndrome (WPW), is a cardiac disorder that affects the electrical system of the heart. It is characterized by an extra electrical pathway, known as an accessory pathway, which allows electrical signals to bypass the usual route through the atrioventricular node. This leads to abnormal fast heart rhythms, called arrhythmias, which can result in palpitations, dizziness, and even fainting. Synonyms for Pre Excitation Syndrome include WPW syndrome, ventricular pre-excitation, or simply WPW. These terms are often used interchangeably to refer to this specific heart condition. It is important for individuals with WPW to receive appropriate medical evaluation and treatment to manage their symptoms and reduce the risk of complications.
