Why the study?
Does narrower paced QRS duration from pacing the right ventricular outflow tract septum predict preserved left ventricular function in patients with permanent pacemakers?
Does narrower paced QRS duration from pacing the right ventricular outflow tract septum predict preserved left ventricular function in patients with permanent pacemakers?
Narrower paced QRS duration from right ventricular outflow tract septal pacing may predict relatively preserved ventricular function over a one-year follow-up.
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.
