atrial flutterAtrial 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 ...
Atrial fibrillation (AF) has been recognized as a distinct rhythm since the beginning of the 20th century. 1 In clinical practice, AF is the most common sustained arrhythmia encountered, yet it remains one of the greatest challenges in the field of heart rhythm disorders. Based on epidemiologic...
Atrial fibrillation and atrial flutterAtrial fibrillation is the most common arrhythmia in clinical practice. It affects 1-2% of the general population and it is estimated that this prevalence will be doubled in the next 50 years due to the progressive aging of the population. Atrial fibrillation...
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...
The creation of an interventional procedure effective in curing atrial fibrillation (AF) started with the surgical Maze procedure conceived and proposed by Cox in 1991 [1]. Electrophysiologists have tried since then to replicate the partitioning of the atria, performed by the surgeon with linear inc...

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...
Abbreviations for Atrial Fibrillation: AFib, Afib, AF, afib Abbreviations for ventricular fibrillation: VFib, Vfib, VF, vfib Caution should be taken when using the short form “AF.” AF is also a short-form term for another similar heart arrhythmia – atrial flutter –that is closely related...
During pacing-induced atrial fibrillation in humans, three responses have been observed: types I, II, and III. The irregularity, complexity, and incidence of continuous electrical activity and reentry increase from type I to type III.59With type I, which resembles atrial flutter, a single broad...
