The hemodynamic effects of pacing the outflow tract of the right ventricle were compared to those of pacing the inflow tract of the right ventricle at identical rates over a wide range of rates in subjects with either normal or abnormal A-V conduction. The results demonstrate that the hemodynamic sequelae of pacing the outflow and inflow tracts of the right ventricle are essentially similar and do not differ statistically. This study offers additional evidence of the relatively unimportant role of ventricular asynchrony in the cardiac performance in man.
