MVP is commonly associated with which arrhythmia?

• A. Atrial fibrillation
• B. Paroxysmal supraventricular tachycardia
• C. Ventricular tachycardia
• D. Sinus tachycardia

Answer: (B)

Mitral valve prolapse often presents with palpitations due to supraventricular tachyarrhythmias. The most commonly described association is paroxysmal supraventricular tachycardia, which shows up as sudden-onset, brief episodes of rapid, regular rhythm with a narrow QRS complex. This link is thought to arise from mechanical stretch and autonomic changes around the mitral apparatus that can promote reentrant or triggered atrial/AV nodal activity. While MVP can be seen with other arrhythmias like atrial fibrillation or ventricular tachycardia, the classic emphasis in exam contexts is the tendency toward PSVT. Sinus tachycardia, while common, is not specific to MVP.
