(1) The ECGs Of 84 patients who survived corrective surgery for tetralogy of Fallot were reviewed. The overall incidence of sudden death during at least 5 years period of followup was 4%, mortality being highest in those with CRBBB and LAH (40%). (2) The ratio of leftward to rightward QRS forces projected on the X axis (Rs/Sx) is significantly decreased in postoperative T/F patients. (3) Twenty-seven patients who had corrective surgery for tetralogy of Fallot underwent cardiac catheterization postoperatively. LVEF was mildly, but significantly diminished and LVEDV was increased significantly, while peak dp/dt, Vpm and Vmax were significantly depressed. These findings indicate that patients who had corrective surgery for tetralogy of Fallot have impaired left ventricular function.
