title: Paroxysmal atrial fibrillation and insidious neck pain.
abstract: Paroxysmal atrial fibrillation (AF) is an arrhythmia usually secondary to autonomic imbalance, and it may occur in the absence of any structural heart disease. The case of a patient with paroxysmal AF, in whom the arrhythmia may have been a presenting symptom of a later diagnosed cervical schwannoma, is reported.
