About Cardiolund

Cardiolund operates from a basis of 20 years of research on analysis of atrial fibrillation signals. This has resulted in a product portfolio of advanced ECG signal analysis algorithms, which are particular well-suited for use with simplified ECG measurements, such as those recorded with mobile devices and embedded devices.

The owners of Cardiolund have done extensive research in algorithms for calculation of the Atrial Fibrillation Rate (AFR). AFR has been used in numerous clinical studies investigating atrial signal properties in relation to prediction of DC conversion, drug therapy and ablation therapy outcome and recurrence, for prediction of spontaneous termination in paroxysmal cases of AF, for monitoring of antiarrhythmic drug actions, and for evaluation of spontaneous and intervention-induced autonomic changes.

The software we sell and the services we provide are based on well-tested methodologies and a long experience. We are world experts in analysis of atrial fibrilation (AF) signals. The research behind our work have been presented in 40+ scientific journal papers and our software has been successfully applied to many thousands of ECGs.
