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.

Keywords: Equilibrium radionuclide angiography (ERNA); Paced QRS duration; Right ventricular outflow tract pacing.
