Bringing a paradigm shift to heart health

Cardiac diseases and related premature deaths are the top burden in health care globally – 49 million people suffer from heart diseases in Europe alone. CardioSignal, a smartphone app approved as a medical device, helps detect atrial fibrillation, making monitoring heart health more accessible to people.

CardioSignal is a brand and a product by Precordior, a Finnish health technology company.The solution measures micro-motions of the chest using the accelerometer and gyroscope which can already be found from most smartphones. The non-invasive, cloud-based automated analysis of motion data provides a new way for general practitioners (GPs) to accurately assess heart-atrial fibrillation (AFib). The company aims to expand the capabilities to other heart diseases in the future.
