Paroxysmal atrial fibrillation can only be diagnosed during episodes when the arrhythmia is present.
The investigators hypothesize that the activation of the atrial myocardium resulting in the p-wave of the ecg should display abnormalities in diseased atria which are vulnerable for AF.
|Condition or disease||Intervention/treatment|
|Atrial Fibrillation||Device: ECG|
In the first part of this trial different diagnostic techniques to detect arrythmogenic substrates of atrial fibrillation will be tested. If suitable parameters can be identified, a follow up trial to identify patients at risk for AF will be conducted before a stroke happens.
Parameters tested are
- Electrophysiological differences between patients with paroxysmal AF and no history of AF
- "Vascular Stiffness" detected by an iPhone app
All patients will undergo a cardiogoniometrie and a pulse wave analysis with an iPhone. Each exam takes 5 minutes.
|Study Type :||Observational [Patient Registry]|

No Intervention is planned. All patients receive a 5 Minute ECG and have their pulse recordes by an iPhone.
Patients receive a 5 Minute ECG recording and have their pulse recorded by an iPhone.
- Beat to beat variation of the electrical activation vector of the atrium [ Time Frame: Once during the exam (baseline) - No further follow up planned ]Test if the beat to beat Variation of the electrical activation of the atrium differentiates between the group of patients with paroxysmal AF and no AF in history.
- Averaged slope of pressure-curve [ Time Frame: Once during exam (5min, baseline) - No further follow up planned ]Test if the steepness of the slope of the pressure curve recorded with the iPhone differs between the two Groups.
- Averaged slope of pressure-curve [ Time Frame: Once during exam (5min, baseline) - No further follow up planned ]Test if the steepness of the slope of the pressure curve recorded with the iPhone correlates with cardiovascular risk factors.
- Heart rate variability [ Time Frame: Once during exam (5min, baseline) - No further follow up planned ]Test if heart rate variability recorded with the iPhone differs between the two Groups.
