Analysis for Atrial Fibrillation using economical and accurate technology and the algorithm employ methods including Lorenz Plots and Shannon Entropy.
Deterministic analysis was performed as Poincare plot analysis, also known as Lorenz plot analysis.
T-wave morphology changes in Holter ECG and Lorenz plot of long term respiratory signals for elderly persons are analyzed.
The algorithm uses Lorenz plots to evaluate beat-to-beat variations in the heart rhythm in several min time intervals.
When autonomic nervous system disorders occur, angina or myocardial infarction might be painless, which greatly increases the risk of cardiovascular disease events. Therefore, cardiac autonomic dysfunction is usually considered to be a risk factor for cardiovascular disease, and a major cause of morbidity and mortality in diabetes.
Non-linear indices include the Lorenz plot, complexity degree and approximate entropy.
When devices with validated algorithms (i.e., Lorenz plots) for AF detection were utilized, a high prevalence of occult AF was detected.
