Accurate detection of atrial fibrillation and atrial flutter using the electrocardiomatrix technique.
Journal of Electrocardiology 2018 August 12
BACKGROUND: Atrial fibrillation (AFIB) and atrial flutter (AFL) are two common cardiac arrhythmias that predispose patients to serious medical conditions. There is a need to accurately detect these arrhythmias to prevent diseases and reduce mortality. Apart from accurately detecting these arrhythmias, it is also important to distinguish between AFIB and AFL due to differing clinical treatments.
METHODS: In this study, we applied a new technology, the electrocardiomatrix (ECM) invented in our lab, in detecting AFIB and AFL in human patients. ECM converts 2D ECG signals into a 3D color matrix, which renders arrhythmia detection intuitive, fast, and accurate. Using ECM, we analyzed the ECG signals from the online MIT-BIH Atrial Fibrillation Database (PhysioNet), and compared our ECM-based results to manual annotations based on ECG by physicians.
RESULTS: Results demonstrate that ECM and PhysioNet annotations of AFIB and AFL agree more than 99% of the time. The sensitivities of the ECM for AFIB and AFL detection were 99.2% and 98.0%, respectively, and the specificities of the ECM for AFIB and AFL were both at 99.8% and 99.8%.
CONCLUSIONS: This study demonstrates that ECM is a reliable method for accurate identification of AFIB and AFL.
