About atrial fibrillation (AFib or AF)
AFib can be considered an "electrical storm" in the atria in which all synchronized activities have disappeared, and the necessary coordination of the contraction stops. This can lead to a number of symptoms including palpitations, shortness of breath, and in some patients, heart failure. AFib is also a major risk factor for stroke, as stagnant blood in the atrium during AFib may lead to the formation of a clot, that can migrate to the brain. This is why AFib is such an important risk factor for heart failure and stroke and a major reason for loss of quality life.

AFib is expected to reach 12.1 million patients in the US by 2030.[1] Prevalence of arrhythmias increases with age and total annual costs for treatment of AFib in the US were estimated already in 2001 at US$6.65 billion[2]. Evidence suggests a higher prevalence of AFib in patients with hypertension, heart failure, coronary heart disease, obesity and diabetes. In addition, recent studies show that 20-30% of patients with ischemic stroke have had AFib before, during or after the initial event[3]. AFib increases the likelihood of stroke by four to five times while AFib-induced strokes are generally associated with more severe damage[4].
