The heart has two upper chambers and two lower chambers. Atrial fibrillation is a condition in which the upper chambers of the heart to contract a very high rate and in a totally disorganized way. The risk of developing atrial fibrillation increases with age, AF button four percent of those 80 years. The heart contracts (beats) and pumps blood with a regular rhythm, for example, at a rate of 60 beats per minute there is a beat every second. The frequency of pulses in the atria can range from 300 to 600 beats per minute.

Atrial fibrillation is often asymptomatic, but can produce symptoms of palpitations, fainting, chest pain, or even heart failure. In addition, the erratic movement of atria leads to blood stagnation (stasis) which increases the risk of blood clots that can travel from the heart to the brain and other domains. Several drugs as well as electrical cardioversion may be used to convert AF to normal heart rhythm. Surgical and catheter-based therapies may also be used to prevent atrial fibrillation in some people. People with AF are often given blood thinners such as warfarin to protect them blows.

Causes of atrial fibrillation

Common causes of atrial fibrillation:

Heart failure.

Congenital heart disease.

chronic lung disease.

Heart valve disease.

After cardiac surgery.

Pulmonary embolism.

Hypertension (high blood pressure).

Cardiomyopathy.

Hyperthyroidism.

Symptoms of atrial fibrillation

Some symptoms of atrial fibrillation:

Confusion.

Weakness.

Breathlessness.

Fainting.

Pulse may feel rapid, racing, pounding, floating, or it may feel too slow.

Chest pain.

Dizziness.

dizziness.

Fatigue.

Treatment of atrial fibrillation

Drugs (such as ibutilide) can sometimes restore normal heart rhythm. These drugs are administered under medical supervision, and are delivered through an IV tube into a vein, usually in the arm the patient.

electrical cardioversion may be used to restore normal heart rhythm by electrical shock if the product fails to improve no symptoms.

Surgery may be used to disrupt electrical circuits that generate AF.

Radiofrequency ablation can be effective in some patients when medications do not work. In this procedure, thin flexible tubes are inserted into a blood vessel and directed to the heart muscle. Then a burst of radiofrequency energy is delivered to destroy tissue that triggers abnormal electrical signals or block abnormal electrical pathways.

Atrial pacemakers can be implanted under the skin to regulate heartbeat.

Medications are used to slow the rapid heart rate associated with AF. These treatments may include medications such as digoxin, beta blockers (atenolol, metoprolol, propranolol), amiodarone, disopyramide, calcium antagonists (verapamil, diltiazam), sotalol, flecainide, procainamide, quinidine, propafenone, etc.
