 - Project Plan Based on the current patient volume in the ICD clinic, and the rate of new ICD implants, it is estimated that enrolling 250 patients will take 3 years. The study will conclude when the last enrolled patient has been followed for 2 years. The follow-up period will, therefore, be 2-5 years for patients enrolled in the study. The total study duration is therefore expected to be 5 years.
