If right bundle branch block progresses to complete heart block, the patient may experience fatigue, exercise intolerance, dizziness, syncope, or sudden death. Some patients who have undergone tetralogy of Fallot repair and have a right bundle branch block pattern and a markedly prolonged QRS may be at increased risk for ventricular tachycardia or sudden death.
