After completing the measurement with the Coala Heart Monitor, the app shows the result of the measurement. Coalas Heart Monitor system can indicate and detect the most common arrhythmias, including atrial fibrillation.
The monitors sensors capture and interpret the heart’s electrical signals, which are then analyzed by smart algorithms. Atrial fibrillation is detected based on analysis of both P-wave and R-R variability in the ECG measurement. The Coala Heart Monitor can be used for intermittent arrhythmias and to monitor the heart over time if one wishes to.
