Article Reviews on Atrial Fibrillation
Atrial fibrillation is a kind of cardiac arrhythmia, which is featured by brief periods of rapid and irregular contractions at the rate of 300 to 400 beats per minute. Such a phenomenon results from the circus movements of impulses generated in the SA node. The circus movements are due to the irregularities or loss or disorientation of the normal atrial musculature. The present article will portray a literature review on atrial fibrillation from various scholarly articles.
Arrhythmia refers to the irregularity in heartbeat or disturbance in the rhythm of the heart. In arrhythmias, the heartbeat may become faster or slower, or might be supplemented by an extra beat or a missed beat. Most of the time such beats may be prolonged or become constant over time. The common symptoms of atrial fibrillation include palpitations, fainting, and shortness of breath, chest tightness, or chest pain (Mischke et al., 2013).
Various types of atrial fibrillation can be noted in clinical situations. Hence, it may be paroxysmal (with recurrent episodes of arrhythmia that ends on its own within 7 days), it may be permanent (with recurrent episodes of arrhythmia that lasts more than 7 days), it may be persistent (permanent arrhythmia over time) or first detected (only one diagnosed episode of arrhythmia) (Munger, Wu & Shen, 2014).
Maintenance of normal rhythmic activity of the heart is extremely important for distributing blood towards various end organs. Atri…
