A young athletic female presents with recurrent palpitations which have been as fast as 250 beats per minute.
What is the underlying condition causing her arrhythmia?
Answer: This patient has Wolff-Parkinson-White syndrome (WPW), a condition in which the presence of an accessory pathway leads to preexcitation and symptomatic arrhythmias. Following treatment of the acute arrhythmia, long-term management can be accomplished by ablation of the accessory pathway or antiarrhythmics.
