Cardiac arrhythmia means abnormal being, the rhythm of the heart. In the normal heart rhythm from node, sine the beginning and after the transfer to the node, atrial-ventricular be released. The result of this syntax directs the electrical stimulation, the atrium, and with a little distance shrunk and are also the first muscles become loose and then shell.

atrial fibrillation(Fibrillation) is a type of cardiac arrhythmia, that electrical stimulation of the route, certain in the heart, during not. Atrial fibrillation (AF) occurring when a can adopt in wave electrical stimulation, the direction of certain have, namely muscle cells atrium for irregular stimulates and relaxes. The result of this problem, we firstly, the contraction of the regular atrium not so can't blood for a full pumping. secondly, often ventricle from the atrium the subordination does not and ventricle for herself shrunk.
