ΔLV SF – change of left ventricular shortening fraction ΔQRS – change of paced QRS duration after pacemaker implantation vs intrinsic QRS duration before pacemaker implantation CCHD – patients with complex congenital heart disease ICAVB – patients with isolated congenital complete or advanced AV block ISHD – patients with isolated structural heart disease NS – not significant | ||||
