-Treated with optimal and unchanged CHF treatment and dosages for at least 4 weeks before selection,
-Treated with a maximal tolerated dosis beta-blocker for at least 3 months before selection (Patient can receive less than the daily target dose of the beta-blocker recommended in the ESC guidelines 2008)
- Regular sinusal or atrial rhythm, paced or spontaneous, and provided that atrial contraction preceeds ventricular contraction;
-Documentation of an average number of at least 100 PVCs per hour on a 48-hour Holter-based ECG recording (performed between the selection and the inclusion visit),
