Actual (reported)With the use of esophageal Holter electrocardiography (eECG), the investigators will look for surrogate markers of paroxysmal atrial fibrillation. To do so, the investigators will record eECGs in patients with known paroxysmal atrial fibrillation but at the time of eECG-recording in sinus rhythm. To identify markers, the eECGs of those patients will be compared to a group of controls in sinus rhythm without atrial fibrillation. The investigators hypothesis is that it is possible to identify surrogate markers in patients with paroxysmal atrial fibrillation.

Cases: 30 patients with known paroxysmal atrial fibrillation (pAF) will consecutively be recruited from the cardiology ward and the cardiological ambulatory. They will form the "cases" group.
Controls: For every case patient, an age (+/- one year) and gender matched control person (n=30) without known paroxysmal atrial fibrillation will be included and matched to every case patient.
The study population consists of patients hospitalized on the cardiology ward (for any reasons). Additionally, also patients referred to the cardiology ambulatorium for a long-term ECG will be asked to participate the study.
