 Atrial fibrillation, also known as AF or Afib, is an abnormal and irregular heart rhythm in which electrical signals are generated chaotically throughout the upper chambers atria of the heart. According to the NICE clinical guidelines, a patient who experiences recurrent two or more AF episodes that terminate spontaneously without any treatment in less than seven days, and usually within 48 hours is classified as having paroxysmal AF. It has been shown that paroxysmal AF comprises approximately between 25 and 62 of cases of AF, and it is estimated that both its incidence and prevalence are likely to rise as the worldwide population ages dramatically over the next twenty years. Interestingly, hospitalizations due to AF have increased sharply in the US during the last decade, posing thereby a heavy economic burden on the health care system and society.
