Overview
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. [1][2]
Electrocardiogram
Key EKG Findings in Pulmonic regurgitation
EKG findings among patients with pulmonary regurgitation (PR) may include the following:
- EKG findings demonstrated in chronic PR are non specific.
- Among patients with tetralogy of Fallot (TOF) 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]
- Among patients with RV volume overload and isolated PR, QRS prolongation with rSr morphology can be seen in right precordial leads.
- RBB is common among the majority of patients who have tetralogy of Fallot repair with right ventriculotomy.
- Ventricular tachycardia is demonstrated on EKG among patients with PR and RV dilatation.[3]
- Due to PR, chronic RV volume overload has been associated with a prolonged QRS. All patients with ventricular tachycardia or sudden death have demonstrated QRS duration of ⩾180 ms.[1]
- Patients may develop atrial flutter/fibrillation after years of PR development.[3]
