Problem
Detecting atrial fibrillation early is difficult because traditional ECG equipment is bulky, requires clinical visits, and many patients are asymptomatic, leading to missed diagnoses and increased risk of stroke and heart failure.
Solution
CardioSignal offers a CE‑marked Class IIb medical device that turns a standard smartphone into a diagnostic tool for atrial fibrillation detection. Using patented gyrocardiography, the app records heart motion via the phone’s accelerometer and gyroscope during a one‑minute, hands‑free measurement placed on the chest. Clinically validated studies report 96 % accuracy for identifying signs of atrial fibrillation. Results, including heart rate and a cardiogram, are displayed instantly in the app and stored in a secure cloud, enabling users to track trends, set measurement reminders, and share histories with healthcare providers. The solution supports self‑monitoring, remote patient care, and point‑of‑care screening in clinics, pharmacies, and hospitals, facilitating timely medical assessment and reducing complications.
Target Audience
Primary users are adults at risk for atrial fibrillation—including those with hypertension, diabetes, or advanced age—and healthcare providers such as primary‑care physicians, cardiologists, nurses, and pharmacists seeking scalable screening tools.
