Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Near infrared spectroscopy (NIRS) is a technique that measures regional cerebral oxygenation in a non-invasive manner. Through the use of near infrared light, the difference between oxygenated and deoxygenated hemoglobin can be measured. By applying the Lambert-Beer law, a numeric result can be calculated.

Since atrial fibrillation (AF) has been linked with an increased risk for the development of neurocognitive deficits, a longer period of AF might be associated with a higher risk for neurocognitive deficits.

It is hypothesized that there is an increase in the regional cerebral oxygen saturation (rSO2) of patients with paroxysmal or persistent AF after successful cardioversion.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

Written informed consent by the patient is asked before cardioversion and participation in the study. Patient anamnesis is assessed by standardized questionnaire.

Patients perform several standardised neurocognitive tests to obtain a general view on the neurocognitive status (auditory verbal learning test, mini-mental state examination, trail making A and B, digit-symbol coding and RAND 36 Health Survey).

Cerebral oxygenation is observed during cardioversion by means of the SenSmart Model X-100 (Nonin). Additional parameters (pulse oximetry, cardiac output, arterial blood pressure, 6-lead electrocardiography (ECG), left ventricular ejection fraction) are recorded. All measurements are performed non-invasively. Patients receive standard treatment following the clinical guidelines.
