3:04 Tachycardia: Atrial Fibrillation: PathogenesisClinical Presentation AF is often asymptomatic.[1,14,21] If patients experience symptoms, these are often nonspecific and variable . Palpitations Tachycardia Chest pain Fatigue Dyspnea Syncope Confusion Mild dyspnea Embolic event If symptoms ar...
About an hour so before the person suddenly collapses due to ventricular fibrillation, some people may have these signs and symptoms. Dizziness Nausea Shortness of breath Chest pain and/or tachycardia How do the EKG patterns differ for AFib and VFib? The EKG patterns in most cases are diagnost...
This channel includes news and new technology innovations for the treatment of atrial fibrillation, also referred to as AF or afib. AF is a cardiac arrhythmia caused by irregular and often rapid heart rate. It is caused by the upper chambers (the atria)
Atrial fibrillation (AF) is associated with various major adverse cardiac events such as ischemic stroke, heart failure, and increased overall mortality. However, its association with lethal ventricular arrhythmias such as ventricular tachycardia (VT), ventricular flutter (VFL), and ventricular fibrillatio...
of Life in Patients With Atrial Fibrillation JAMA Original Investigation April 2, 2019 This open-label randomized trial compares the effect of pulmonary vein isolation via catheter ablation vs rate and rhythm control using drug therapy on the quality of life of patients with atrial fibrillation. ...
BACKGROUND: Atrial tachycardia (AT) that develops after ablation of atrial fibrillation often poses a more difficult clinical situation than the index arrhythmia. This study details the use of an impedance-based electroanatomic mapping system (Ensite NavX) in concert with a specialized multielectrode...
The optimal management of atrial fibrillation is of considerable clinical importance, and with the recent publication of four studies suggesting the equivalence of rate and rhythm control strategies, new attention has been focused on rate control. Reasons for rate control include reduction of symptoms ...
Atrial fibrillation (Afib) and ventricular fibrillation (Vfib) are both a type of abnormal heart rhythm (arrhythmia). Atrial fibrillation is caused by irregular electrical impulses in the atria and ventricular fibrillation is caused by irregular electric
2. 房性心动过速(atrial tachycardia)简称房速,指起源于心房且无需房室结参与维持的心动过速。发生机制包括自律性增加、折返与触发活动。根据起源点不同,分为局灶性房性心动过速(focal atrial tachycardia)和多源性房性心动过速(multifocal atri...
