In stroke survivors, atrial fibrillation is typically detected with short-term electrocardiogram (ECG) monitoring in the stroke unit. Prolonged continuous ECG monitoring is impractical and requires substantial resources while insertable cardiac monitors are invasive and costly. Chest and thumb-ECG could provide an alternative for atrial fibrillation detection post-stroke.
The primary objective of our study is to assess the incidence of newly diagnosed atrial fibrillation during 28 days of chest and thumb-ECG monitoring in patients with cryptogenic stroke. Secondary objectives are to assess Health-related Quality of Life using Short Form-36 and the feasibility of the Coala Heart Monitor in patients with stroke.

- Diagnostic Test: chest and thumb- ECG
chest and thumb- ECG using the Coala Heart Monitor
- Cumulative incidence of atrial arrhythmia [ Time Frame: 28 days (prospectively) ]Cumulative incidence of atrial arrhythmia at 28 days.
- Previous atrial arrhythmia [ Time Frame: 10 years (retrospectively) ]The prevalence of previously known atrial arrhythmia before cryptogenic stroke and the number of these patients who had anticoagulant therapy.
- Compliance with chest and thumb-ECG [ Time Frame: 28 days (prospectively) ]Compliance with chest and thumb-ECG at week four (number of recorded scheduled ECG tracings).
- Patient-reported experience with chest and thumb-ECG [ Time Frame: 6 weeks (prospectively) ]Patient-reported experience with chest and thumb-ECG measured at week six
- Health-related Quality of Life [ Time Frame: 12 months prospectively ]Health-related Quality of Life (Short Form-36) at week 6 and at 12 months and the association with atrial fibrillation and compliance with chest and thumb-ECG.
- Cumulative incidence of stroke [ Time Frame: 3 years prospectively ]Cumulative incidence of stroke (and all-cause mortality) after three years in patients with atrial fibrillation versus without atrial fibrillation.

Ages Eligible for Study: | 18 Years and older (Adult, Older Adult) |
Sexes Eligible for Study: | All |
Accepts Healthy Volunteers: | No |
Sampling Method: | Probability Sample |
Inclusion Criteria:
- Patients, aged ≥18 years, with a validated diagnosis of ischemic cryptogenic stroke are eligible for the study.
Exclusion Criteria:
- For screening with chest and thumb-ECG, exclusion criteria are as follows: previously known atrial arrhythmia with an indication for anticoagulation, implantable defibrillator, pacemaker or insertable cardiac monitor, pregnancy, permanent indication for anticoagulation (including low-molecular weight heparin) due to atrial arrhythmia, mechanical heart valve, deep vein thrombosis, or pulmonary embolism. Patients with a life expectancy ≤6 months (e.g. severe heart failure New York Heart Association functional class IV or malignancy) are likewise excluded.
