[3] [4] Medications used to restore a normal heart rhythm (antiarrhythmics) such as ibutilide effectively control atrial flutter about 80% of the time when they are started but atrial flutter recurs at a high rate (70–90% of the time) despite continued use. [1] Atrial flutter can be treated more definitively with a technique known as catheter ...
The percentage of people with AF increases with age with 0.1% under 50 years old, 4% between 60 and 70 years old, and 14% over 80 years old being affected. [4] A-fib and atrial flutter resulted in 193,300 deaths in 2015, up from 29,000 in 1990. [29] [30] The first known report of an irregular pulse was by Jean-Baptiste de Sénac in 1749. [3]
