A computerized approach of nonlinear dynamics analysis of electrocardiogram (ECG) signals was applied for the detection of coronary artery disease (CAD). The proposed nonlinear dynamics descriptors were derived from 12-lead rest ECG data, and evaluated by originally developed computer software. Fluctuations of potentials of ECG leads that occur during the(More)
Cardiovascular diseases remain the main cause of morbidity and mortality in Lithuania, and early detection of those diseases is one of opportunities to reduce this problem. Usage of information technologies including clinical decision support systems, telemedicine networks and computer analysis of cardiac signals, can serve this purpose. Therefore, the(More)
