Description of intervention(s) / exposure
Any person eligible for screening will be asked to participate and provided with written information about the study. The process of screening will be explained including the sharing of the screening results with their general practitioner/family physician. The screening will be free of charge to the participants and verbal informed consent will be obtained prior to conducting the screening. The screening protocol will take approximately 5-10 minutes and includes the following:
i) Initial brief medical history to include capturing of co-existing medical condition(s) and medication history;
ii) Measurements of weight, height and blood pressure with an automated machine. If the resting blood pressure is elevated (Systolic >130mmHg), an additional reading will be performed.
iii) Single lead ECG recording of 30-60s using the AliveCor Kardia device. The automated diagnostic function of the device will provide on the spot analysis as “normal” or “Possible Atrial Fibrillation".

Summary
Brief summary
TEFF-AF study will provide crucial epidemiological understanding of the cardiovascular risk profile and Atrial Fibrillation burden in the Ethiopian population. Healthy ambulant adults living in the catchment areas of Soddo Christian Hospital, Ethiopia will be invited to participate in a screening protocol involving; (1) Initial brief medical history of existing medical condition(s) and medication history; (2) Measurements of weight, height and blood pressure with an automated machine; and (3) Single lead ECG recording of 30-60s using the AliveCor Kardia device which will detect suspected AF. It is hypothesized that the cardiovascular risk factor profile of Ethiopians will be a determining factor in the prevalence of AF.
