text: EKG findings among patients wit chronic<unk><unk>  (PR) may be non-specific. Ventricular tachycardia is demonstrated on EKG among patients with PR and RV dilatation. Patients may develop atrial flutter/fibrillation after years of PR development. Among patients with tetralogy of Fallot (TOF), increased QRS duration with widened QRS complex reflects the severity of PR and right ventricular dilation predisposes the patients to develop malignant arrythmias.
