Frontal QRS-T angle and ventricular mechanics in congenital heart disease

The QRS-T angle has been associated with adverse cardiovascular events and sudden cardiac deaths. We determined frontal QRS-T angle in patients with complete transposition of the great arteries (TGA) after atrial switch operation and repaired tetralogy of Fallot (TOF) and explored its relationships with ventricular mechanics. Thirty TGA patients aged 32.3 ± 4.4 years after atrial switch operation and 47 repaired TOF patients aged...
