[Comparative hemodynamic study of ventricular and sequential stimulation].
Cardiac catheterization was performed in 10 patients to compare the haemodynamic effects of ventricular stimulation and the sequential stimulation by measuring cardiac output and aortic pressure in both types of pacing. During sequential stimulation we had was an increase of 16.4% in cardiac output while there was increase in aortic and a decrease in pulmonary pressures. They improved significantly the haemodynamic parameters in our patients when compared to the ventricular stimulation.
