Abstract

Appropriate heart rate in a failing pulmonary ventricle remains unknown, particularly in congenital heart disease with unique hemodynamics. A 71-year-old male with repaired tetralogy of Fallot and a pacemaker for a sinus node dysfunction suffered from heart failure symptoms with preserved left ventricular function. Simply changing the pacemaker’s lower rate from 60 to 75 bpm, New York Heart Association classification improved from III to II, and hemodynamic parameters drastically improved. We regarded this case as informative. Appropriate heart rate could be higher in congenital patients with failing right and non-failing left ventricles than in adults with malfunctioning LV.
