That said — most patients eventually do become symptomatic ( Webb and Gatzoulis: Circulation 114: 1645-1653, 2006 ). Because of this, it is uncommon to see sinus tachycardia with a prolonged PR interval. Surprisingly, patients with an ASD may present for medical attention at any age. Many patients go years without significant symptoms.
