Brief Summary
This is a prospective, non-interventional cohort study. It tests the hypothesis that
- Pacemaker-derived monitoring of sleep-related breathing disorders and/or daily physical activity predicts clinical outcome.
- Autonomic imbalance defined by an increased periodic repolarisation dynamics (PRD) predicts clinical outcome in pacemaker patients.
- Autonomic imbalance defined by an increased periodic repolarisation dynamics (PRD) predicts the occurrence of device-detected atrial fibrillation and/or device-detected sleep apnea.
- Enviromental factors such as ambient temperature, humidity, precipitation, air pressure impacts device-detected atrial fibrillation and/or device-detected sleep apnea.
- Variation of night-to-night device-detected sleep apnea shows sex-specific patterns and impacts device-detected atrial fibrillation burden, ventricular pacing rate in sick sinus syndrome and clinical outcomes.
- Burden / variation of device-detected sleep apnea and/or device-detected atrial fibrillation correlates with the incidence and severity of common ophthalmologic diseases.

Study Arms (3)
patients with severe sleep apnea
defined by a pacemaker-derived mean RDI ≥ 20/h in the first 12 months after enrollment
patients with autonomic imbalance
defined by PRD ≥ 5.75deg2 (native) and/or ≥ 3 deg2 (paced) assessed within the first 12 months of enrollment
patients with a sedentary lifestyle
defined by a pacemaker-derived mean daily physical activity level \< 2h in the first 12 months after enrollment
Eligibility Criteria
Patients with pacemakers are usually above the age of 65 years, and suffer from common co-morbidities such as arterial hypertension, coronary artery disease, heart failure, COPD, peripheral artery disease, iron insufficiency, sleep disordered breathing, obesity and/or physical inactivity / de-conditioning.
You may qualify if:
- implanted Microport TEO SR/DR or BOREA SR/DR or ALIZEA SR/DR pacemaker device
- signed informed consent
You may not qualify if:
- any contraindication to perform a cardiac CT examination
- eGFR \< 30 ml/min/1.73 m2
- allergy against CT contrast medium
- hyperthyreoism
- inability of the patient to understand the study purpose and plan
- inability of the patient to perform baseline examinations
- pregnancy or breast-feeding; women with childbearing potential
- estimated life expectancy below one year
