Reliable AF detection using a wrist-worn device

A new scientific publication concludes that the PulseOn device can be reliably used for atrial fibrillation (AF) detection in an outpatient setting. Clinical performance is evaluated using the PulseOn Arrhythmia Monitor System that consists of a data management service and a wrist-worn device that combines both PPG and ECG measurements.

Cost-effectiveness of AF screening

The cost-effectiveness of population screening for AF in Sweden has been investigated in a new study. Using simulated population screening results the study shows that an AF screening strategy is cost-effective in 99.2% and cost-saving in 92.7% of the simulations.

Safe automatic screening for AF using Cardiolund ECG Parser

There is a growing interest in identifying AF patients at an early stage to be able to intervene the progression of the condition and to prevent stroke cases. Identifying AF patients may be complicated by factors such as AF being without symptoms (silent AF) for many patients, and the variety of non-critical arrhythmia that are found in ECGs in an ageing population.

Detection of Atrial Fibrillation in home-based ECG measurements

There are multiple challenges when it comes to detection of atrial fibrillation (AF) in simplified home-based ECG measurements. In Cardiolund Research we create software algorithms that overcome these challenges, and enables automatic ECG analysis of simplified home-based measurements, for screening purposes.

On the usefulness of AFR analysis and trending

The atrial fibrillatory rate (AFR) is an exciting topic that I've had the opportunity to research on over the last two decades, in my work with algorithms for signal processing of ECGs. Today we have a state-of-the-art algorithm for calculating atrial fibrillatory rate, which has important use cases in the prediction of spontaneous AF termination, or termination induced by DC conversion, anti-arrhythmic drugs and ablation procedures.

What is an ECG parser?

We have built a powerful software tool we call the ECG Parser. This software transforms an ECG signal, or an entire database of ECG signals, into a very detailed description of the content.
