Atrial fibrillation is a multifactorial micro-reentrant phenomenon whereby localized regions of myocardium are automatically excited to produce a rapid and irregular atrial depolarization. In atrial flutter, the arrhythmia appears to follow a circular tract within the atria such that the myocardium that ...
Lone atrial fibrillationis a term that was often used in the past to describe atrial fibrillation that occurred in people without underlying heart disease (4). This distinction was believed to be important because when there is a known underlying cause for the arrhythmia, such as heart surgery, ...
随后,在第9到11层中专门设置IENN结构以进行最终标识。在此结构的每一层中,神经元的数量分别设置为30、16和3。为了更好地区分每个ECG段属于NSR,AF或AFL,在最后一层中将softmax函数用作激活函数,这主要取决于类别概率的类别。其他层的激活功能都是漏电整流器线性单元(LReLU)功能。实现了Xavier算法以初始化模型的权...

Atrial Flutter vs. Atrial Fibrillation Atrial flutter is similar to another,much more commonarrhythmia calledatrial fibrillation, or AFib. The two share many of the same symptoms, likedizzinessandheart palpitations, in which you can feel your heart racing, pounding, or skipping beats. However, it...
Atrial fibrillation (AF) and atrial flutter (AFl) are two of the most frequent causes of prolonged palpitations [1]–[8] in young competitive athletes, even including those per forming sport activities at an elite level. Specifically, th... AA Bove - 《Acc Current Journal Review》 被引量:...
AFib vs. atrial flutter Both are problems with your heart's beating. When you have atrial flutter, your heart beats too fast but still mostly in a regular rhythm. When you have AFib, your heart's rhythm is irregular. Types of Atrial Fibrillation One of the tests you might have for atria...
Atrial flutter/fibrillation (AFL/Af) is a common late complication in atrial septal defect (ASD) patients even after occluder implantation. We try to delineate the risk factors of persistent AFL/Af. From 1998 to 2010, all patients older than 18years of age who received ASD occluder implantation...
New Antiarrhythmic Drugs for Atrial Flutter and Atrial Fibrillation A Conceptual Breakthrough at Last? Antiarrhythmic drug (AAD) use in the clinical setting remains an often frustrating empirical exercise, despite significant advances in understanding the effect of AADs on myocardial ion channels and ...
