Frequency Analysis of Atrial Fibrillation From the Surface Electrocardiogram
Atrial fibrillation (AF) is the most common arrhythmia encountered in clinical practice. Neither the natural history of AF nor its response to therapy are sufficiently predictable by clinical and echocardiographic parameters. Atrial fibrillatory frequency (or rate) can reliably be assessed from the surface electrocardiogram (ECG) using digital signal processing (filtering, subtraction of averag...
متن کاملSurface ECG organization analysis to predict paroxysmal atrial fibrillation termination
The aim of this work is to predict non-invasively if an AF episode terminates spontaneously or not by analyzing the increase of atrial activity organization prior to paroxysmal atrial fibrillation (PAF) termination. Sample entropy was selected as non-linear organization index. Synthetic PAF signals were used to evaluate the notable impact of noise in AA organization estimation. Three strategies...
متن کاملIntravenous Methylprednisolone, a Possible Cause of the Atrial Fibrillation
We are presenting a case illustrating atrial fibrillation (AF) following the use of methylprednisolone in a patient with pelvic and femur fracture. A 48- year- old man with no significant past medical history, was admitted to the emergency department after injury in a car accident. He suffered a multiple bone fracture with chief complaints of pain and shortness of breath. He was transfer...
متن کاملElectrocardiogram Characteristics that Distinguish Perimitral Reentry from Other Atrial Tachycardias after Atrial Fibrillation Ablation
Introduction: Ablation of Atrial Fibrillation (AF) can induce several types of Atrial Tachycardias (ATs). Perimitral reentry is a common mechanism among postablation ATs. The electrocardiographic (ECG) criteria for differentiating perimitral reentry from other postablation ATs may be useful in clinical practice. Methods and results: A total of 48 consecutive post atrial fibrillation ablation pa...
متن کاملMeasures of organization during atrial fibrillation.
Atrial fibrillation, a rhythm classically described as totally disorganized, is now recognized to have some structure in its activation. Even though that structure may be very complex, it clearly exists, and researchers continue to try to quantify that structure. One problem with this quantification is that "organization" is an ambiguous term that can have many interpretations. Rather than atte...
