Wolff-Parkinson-White Syndrome: A Master of Disguise.

Wolff-Parkinson-White syndrome is the most common form of ventricular preexcitation and affects 1-3 per 1,000 persons worldwide. Many patients remain asymptomatic throughout their lives; however, approximately half of the patients with Wolff-Parkinson-White syndrome experience symptoms secondary to tachyarrhythmias, such as paroxysmal supraventricular tachycardia, atrial fibrillation, atrial flutter, and, rarely, ventricular fibrillation and sudden death. Patients with Wolff-Parkinson-White syndrome may present with a multitude of symptoms such as unexplained anxiety, palpitations, fatigue, light-headedness or dizziness, loss of consciousness, and shortness of breath. We report the case of a patient who presented with a plethora of symptoms related to generalized anxiety along with several confounding factors such as psychosocial stressors, chronic fatigue secondary to high physical and mental demands at work, a strong family history of anxiety, and a history of substance abuse. Keeping cardiac dysrhythmia within his differential diagnosis allowed for accurate diagnosis and treatment.
