Filter by:Aim of present study is to examine the short and long-term results of pacing from right ventricular apex and to compare them with those of biventricular pacing.
The purpose of this study is to determine whether there is a relationship between ventricular lead position and the incidence of heart failure and atrial fibrillation in patients with indication for permanent pacemaker stimulation.
Heart failure is a progressive disease that decreases the pumping action of the heart. This may cause a backup of fluid in the heart and may result in heart beat changes. When there are changes in the heartbeat, sometimes a pacemaker is used to control the rate and rhythm of the heartbeat. In this trial, the researchers will test if pacing both the left and right lower half of the heart (ventricles) will: - decrease the number of hospital and clinic visits due to heart failure symptoms - extend life - delay heart failure symptoms as compared to those who are paced in only one ventricle (the right ventricle)
The primary purpose of the study is to evaluate if patients with a standard indication for permanent ventricular pacing, left ventricular ejection fraction without limit, or any QRS duration will profit from the prevention of ventricular desynchronisation.
