Electrophysiology: Catheter Ablation of Atrial Fibrillatio

Atrial fibrillation occurs when rapid, disorganized electrical signals cause the heart's two upper chambers (the atria) to contract very quickly and irregularly (fibrillate). Atrial fibrillation causes blood to gather in the atria because it is not pumping completely into the ventricles (the lower chambers of the heart) In addition to Akron General's Atrial Fibrillation (Afib) Center, our Electrophysiology (EP) Services help patients manage and treat a full spectrum of heart rhythm disorders. Also called arrhythmias, heart rhythm disorders may be harmful and possibly life-threatening, if not treated Vagal activity is thought to influence atrial electrophysiological properties and play a role in the initiation and maintenance of atrial fibrillation (AF). We evaluated the effects of acute vagal stimulation on atrial conduction, refractoriness of atrial and pulmonary veins (PVs) and inducibility o Shi R, Parikh P, Chen Z, et al.

The electrophysiology of atrial fibrillation (AF) has always been a deep mystery in understanding this complex arrhythmia. The pathophysiological mechanisms of AF are complex and often remain unclear despite extensive research. Therefore, the implementation of basic science knowledge to clinical practice is challenging During atrial fibrillation the typically organized electrical activation of the upper chambers of the heart [Criley sinus rhythm animation] is replaced by disorganized, chaotic electrical activity [Criley AF animation] Atrial fibrillation (AFib or AF) is a condition where the electrical impulse that causes the heart to beat at a normal rhythm is overridden by chaotic signals causing it to beat in a disorganized, irregular manner. AFib originates in the atria—the upper part of the heart—and is the most common heart arrhythmia One of the most common heart abnormalities, atrial fibrillation is an irregular beating of the upper chambers of the heart. Symptoms can include heart palpitations, lightheadedness, dizziness, shortness of breath and chest pain. If left untreated, it can increase a patient's risk of stroke and other health issues Atrial fibrillation is the most common cardiac arrhythmia in clinical practice, and its management remains challenging. A solid understanding of the scientific basis for atrial fibrillation therapy requires insight into the mechanisms underlying the arrhythmia, about which an enormous amount has been learned over the past 10 years

It often begins as short periods of abnormal beating, which become longer or continuous over time. It may also start as other forms of arrhythmia such as atrial flutter that then transform into AF
  6. About Atrial fibrillation (AF) is the most common sustained type of cardiac arrhythmia, characterised by irregularly irregular ventricular pulse and loss of association between the cardiac apex beat and radial pulsation. AF may be paroxysmal, persistent or permanent

Atrial fibrillation. We have exceptional experience treating atrial fibrillation, a type of arrhythmia in which the atria (the two small upper chambers of your heart) beat chaotically. Atrial fibrillation can lead to stroke, congestive heart failure, or cardiomyopathy. Ventricular tachycardia and fibrillation Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia. AF is usually classified according to its temporal pattern as paroxysmal, persistent, or permanent. AF adversely affects cardiac haemodynamics because of loss of atrial contraction and the rapidity and irregularity of the ventricular rate An electrophysiologist inserts catheters - thin, flexible wires - into a vein, typically in the groin or neck, and guides them up to the heart. We perform traditional radiofrequency (heat) ablations and newer cryoablation (extreme cold) procedures to eliminate abnormal electrical pathways in the heart Atrial fibrillation. Atrial fibrillation (AF) is the most common cardiac arrhythmia and a major cause of stroke. In the UK, nearly 1.2 million people have diagnosed AF, and it is estimated that around 500,000 people are undiagnosed.1 The prevalence of AF in the general population is 2% (males > females) and increases with age.2 It is associated with hypertension, coronary artery and valvular.

Atrial Fibrillation. Atrial fibrillation, or A-Fib, happens when the upper chambers of the heart beat very rapidly (300-600 beats per minute) and irregularly. When your heart beats inefficiently, not enough blood is pumped to the rest of your body. This can cause shortness of breath, fatigue and a higher risk of stroke Right Atrial Complexity Evolves With Stepwise Left-Sided Persistent Atrial Fibrillation Substrate Ablation and Predicts Outcomes Nicolas Johner, Mehdi Namdar, Dipen C. Shah Pages 1619-163 Atrial fibrillation (AFib) is the most common abnormal heart rhythm encountered in the aging population. During AFib episodes, the upper chambers of the heart no longer beat in a coordinated manner. Unmanaged AFib can lead to irregular heartbeats and blood clots, which can cause stroke, heart failure, and even death The faculty is working with many companies to develop new tools and techniques to cure atrial fibrillation through a variety of ablation systems, including both radiofrequency and cryoablation.
