Research

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

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

The health survey in Trøndelag (HUNT4)

In the fourth part of the Health Survey in Trøndelag (HUNT4, 2017-2019), over 2,400 participants were examined with cardiac ultrasound and a stress test on a treadmill to measure fitness. In this project, we follow up these participants by mapping heart rhythm disturbances with a focus on atrial fibrillation using ECG247. The data collection with ECG247 started in the spring of 2024. The aim of the project is, among other things, to better understand the underlying factors for the development of atrial fibrillation, with a focus on the connection between heart structure and function and physical form. The project is led by professor Håvard Dalen and postdoctoral fellow Jon Magne Letnes at the Department of Circulation and Imaging (NTNU) and the Department of Cardiology at St Olav’s Hospital.

SNAPS-studien (The Southern Norway Post-stroke Atrial Fibrillation Study)

Sørlandet Hospital HF is responsible for the SNAPS study, which will investigate, among other things, whether ECG247 is better suited to detect atrial fibrillation after stroke compared to today’s standard examinations. Atrial fibrillation as a cause of stroke is treated with a special preventive medicine and it is therefore important to detect the condition. The study will include 450 participants over the age of 18 who have been admitted to the hospital with ischemic stroke from and including 2023. The study is led by dr med Halvor Øygarden.
