-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diagnostic accuracy of a wearable system for atrial fibrillation detection | The wearable system comprises of two integrated components: a photoplethysmography (PPG) and a 6-lead ECG of the device. It works as described below. First, an automatic PPG algorithm will indicate whether atrial fibrillation is suspected. The rhythm assessment of PPG algorithm is based on pulse regularity. Next, a 6-lead ECG is acquired by the wearable. The rhythm assessment of ECG is based on P waves and regularity of QRS complexes. A diagnosis is made by independent cardiologists. The conclusion of a whole system comprising of both described methods will be compared with a gold standard multi-lead Holter ECG. This standard ECG is also evaluated by independent cardiologists. | PPG will be assessed in 2 minutes. ECG will be assessed in up to 10 months. | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Diagnostic accuracy of PPG algorithm of the wearable for atrial fibrillation detection | An automatic PPG algorithm will indicate whether atrial fibrillation is suspected. The rhythm assessment of PPG algorithm is based on pulse regularity. As a separate diagnostic tool it will be compared with a gold standard multi-lead Holter ECG which is assessed by independent cardiologists. | 2 minutes. | 
| Diagnostic accuracy of a 6-lead ECG of the wearable for atrial fibrillation detection | Independent cardiologists will assess the heart rhythm in a 6-lead ECG acquired by the wearable. As a separate diagnostic tool it will be compared with a gold standard multi-lead Holter ECG which is also assessed by independent cardiologists. The rhythm evaluation of ECG is based on P waves and regularity of QRS complexes. | Up to 10 months. |
