Overview
EKG
- EKG findings in chronic PR are non specific.
- In patients with tetralogy of Fallot increased QRS duration with widened QRS complex reflects the severity of PR and right ventricular dilation predisposing the patients to develop malignant arrythmias. [1][2]
- In patients with RV volume overload and isolated PR, QRS prolongation with rSr morphology can be seen in right precordial leads.
- RBB is common in majority of patients who have tetralogy of Fallot repair with right ventriculotomy.
