Atrial fibrillation, is a very common arrhythmia whose incidence increases with age. Atrial fibrillation is not to be confused with ventricular fibrillation , which is quite different, a few minutes to a fatal arrhythmia. Atrial fibrillations are more common since the age of 65. Over 70 years it occurs in about 5 per cent and over 85-year-olds more than 10 percent. Heart with normal sinus rhythm is after shrinking hallways and soon after at the same pace of the heart chambers.
Contraction in atrial fibrillation hallways are normally coordinated, but to vibrate, and the contraction of the ventricles is irregular and without medication often too dense, usually a class of 120-180 times per minute. Wrist feel the pulse is rapid and irregular, and some punches to feel stronger and the weaker part. Because the hallways are Flimmer contraction effectively, can be formed in large porches blood clots, which may leave the bloodstream and end up as the issue of brain blood vessel, and the logs, causing a brain infarction , or stroke. This blood clot formation can greatly reduce the risk of blood clots to prevent warfarin -therapy.
Treatment with warfarin to prevent a year from 60 to 80 percent of strokes, the risk without treatment is 5 percent. Untreated atrial fibrillation of the heart contraction frequency is higher than normal, usually well over 100 times per minute. In addition, contraction is irregular. This high, irregular heart rate and reduce the strain on the heart of the contraction force. digoxin, used to slow the heart contraction frequency to a comfortable level, the frequency 60-90/min. is suitable for the majority of patients.
