What is a common symptom of Wolff-Parkinson-White Syndrome?

Wolff-Parkinson-White (WPW) Syndrome is characterized by a specific type of electrical conduction abnormality in the heart that can lead to episodes of rapid heart rate (tachycardia). The correct answer highlights symptoms associated with this syndrome. Shortness of breath (SOB) and syncope (fainting) are common manifestations that occur during episodes of tachyarrhythmia. During these episodes, the heart can beat excessively fast, which may compromise cardiac output and lead to inadequate blood flow, resulting in shortness of breath and fainting spells.

In contrast, the other symptoms listed, such as severe abdominal pain, general malaise, and persistent hypertension, are not directly associated with WPW syndrome. Severe abdominal pain could indicate a separate gastrointestinal issue, general malaise is nonspecific and could relate to numerous conditions, and persistent hypertension is not a hallmark of WPW but might be associated with other cardiovascular conditions. The urgency and immediacy of the symptoms in WPW—particularly those affecting circulation—make SOB and syncope notable and consistent presenting features.
