Multicenter randomized controlled trial which will include patients with left ventricular ejection fraction \>50% requiring a first implant of a cardiac pacemaker with expected high pacing percentages. Patients will be randomized 1:1 to right ventricular apical pacing vs left septal or deep septal pacing. The primary endpoint will be pacing-induced cardiomyopathy during the first year of follow-up.

All patients in the study will have a clear indication for a permanent pacemaker. The type of device (single or dual chamber) will be chosen as per clinical practice. The only difference between the two groups of the study will be the position of the ventricular lead.

NOT_YET_RECRUITINGPacing-induced cardiomyopathy
Decrease in the left ventricular ejection fraction (LVEF) by \>10% as compared to the LVEF before pacemaker implant and final LVEF\<45%.
Time frame: 12 months
LVEF during follow-up
To compare the mean or median (depending on distribution) LVEF before and one year after pacemaker implant in the two groups.
Time frame: 12 months
Mitral and tricuspid regurgitation
To compare the degree of mitral and tricuspid regurgitation before and one year after pacemaker implant in the two groups.
Time frame: 12 months
New York Heart Association (NYHA) class
To compare the NYHA class one year after pacemaker implant in the two groups.
Time frame: 12 months
Brain Natriuretic Peptide levels
To compare the N-terminal pro-B-type natriuretic peptide (NT-proBNP) levels one year after pacemaker implant in the two groups.
Time frame: 12 months
heart failure
Comparison of heart failure (HF) events in the first year after pacemaker implant in the two groups. HF events will be: hospitalizations for heart failure, emergency department or day-hospital visits for heart failure, heart failure symptoms requiring the initiation of diuretic therapy.
Time frame: 12 months
