About this trial

This is an interventional treatment trial for Hypertension focused on measuring Atrial fibrillation, Pacemaker, AF suppression pacing, Indications for Pacemaker Implantation due to sinus node or atrio-ventricular node disease

Eligibility Criteria

65 Years - undefined (Older Adult)All SexesDoes not accept healthy volunteers

Inclusion Criteria Age ≥ 65 years History of hypertension requiring pharmacological therapy (≥ 4 weeks of therapy). Recent (< 8 weeks) St. Jude Medical Inc. pacemaker implant (IDENTITY® Adx DR (Model 5386/5380)), ICD implant (EPIC 2 or Atlas 2) or other St. Jude Medical Inc. pacemaker or ICD with the same capabilities. In pacemaker patients only the primary indication for pacing is sinus or AV node disease. Exclusion Criteria Previous documented AF, atrial flutter (lasting greater than 5 minutes), or other sustained SVT (not including episodes detected by the device) Geographic/social or psychiatric factor likely to interfere with follow-up Requirement for oral anticoagulation (heart valve, deep vein thrombosis, etc.)

5. Study Description

Brief Summary
In patients with a standard indication for pacing and no previous history of AF, detection of Atrial High Rate Episodes predicts an increased risk of stroke and systemic embolism. Overdrive atrial pacing with the AF Suppression algorithm will reduce the risk of symptomatic AF in patients with standard indication for pacing and no previous history of AF.
