Pulmonic regurgitation electrocardiogram
Pulmonic regurgitation Microchapters
EKG findings in patients wit chronic PR may be non specific. However, in patients with tetrology of Fallot may show increased QRS duration with widened QRS complex. It may reflect the severity of PR and right ventricular dilation predisposing the patient to develop arrythmias. 
- 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. 
- 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.
