    Abstract:
    The hemodynamic changes in 12 children (mean age 6 years) with Tetralogy of Fallot (TOF) were studied during the first 24 hours after surgical correction. The effects of isoprenaline and dopamine were compared. 7 of them using atrial and ventricular pacing also have their effects compared. The results show that patients with small left ventricles generally suffer low cardiac output or a trend to low cardiac output. The chronotropic drug (isoprenaline) was more effective than inotropic drug (dopamine) in increasing CI due to its ability in increasing HR and decreasing SVR. Atrial pacing was an effective method in increasing CI if the atrioventricular conduction is normal, while ventricular pacing did not increase CI at all.
