[Mitral valve prolapse and parasystolic ventricular tachycardia: an unusual association].

Ventricular arrhythmias are common in patients with mitral valve prolapse. Conversely, parasystolic ventricular tachycardia is an uncommon arrhythmia that can be observed independent of preexisting heart disease. We report the case of an otherwise healthy 42-year-old woman with both mitral valve prolapse and parasystolic ventricular tachycardia.
