Background: Right ventricular pacing may be deleterious in patients with left ventricular dysfunction, but in patients with normal function the impact of this stimulation triggering clinically relevant ventricular dysfunction is not fully established.
Objectives: To evaluate the clinical, echocardiographic findings of patients with previously normal left ventricular function underwent implantation of a pacemaker.
Methods: Observational, cross-sectional study with 20 patients, who underwent implantation of pacemaker, prospectively followed-up, with the following inclusion criteria: normal left ventricular function defined by echocardiography and ventricular pacing higher than 90%.
Background: The stimulation of the right ventricle (RV) may be deleterious in patients with ventricular dysfunction; however there is little evidence about the impact of this stimulation in patients with normal ventricular function.
Objectives: To assess the clinical and laboratory evolution of patients with normal ventricular function submitted to implant of artificial cardiac pacemaker (PM).
Methods: 16 patients enrolled according to the following inclusion criteria: normal ventricular function defined by echocardiogram and presence of upper ventricular stimulation > 90% (generator telemetry assessment) submitted to a PM implant were prospectively studied.
