Paced QRS duration predicts left ventricular function in patients with permanent pacemakers – One-year follow-up study using equilibrium radionuclide angiography (ERNA)

Abstract

Permanent pacing, being non physiological, often results in ventricular dysfunction over time. Narrower paced QRS duration from pacing the right ventricular outflow tract septum, might result in relatively preserved ventricular function over long term follow up.
