Research

The ECG247 is a result of many years research in medical technology and cardiology. ECG247 has documented usability and diagnostic accuracy.

ECG247 is in use in several research trials and projects.

Selected clinical trials

The Norwegian atrial fibrillation self-screening trial (NORSCREEN)

The NORSCREEN trial will assess whether self-examination with ECG247, detection of previously unknown atrial fibrillation and initiation of preventive treatment can avoid stroke. The study will include 20,000 participants ≥65 years with up to 5 years follow-up. Oslo University Hospital and professor Sigrun Halvorsen are responsible for the study

AFstudien.no

AFstudien.no has included >2000 participants. The main study aim was to assess whether self-testing for atrial fibrillation was possible. The results of the study will be published soon.
