Atrial Fibrillation

Atrial Fibrillation

Atrial Fibrillation is a heart condition that is characterized by abnormal rhythm of the heart originating in the atria. The heart beats irregularly and ofen rapidly. Persons suffering from AF. High blood pressure or hyperthyroidism can bring on atrial fibrillation. Those suffering from asthma or COPD are at higher risk for developing atrial fibrillation. Atrial fibrillation increases the chances of a person suffering a stroke. Cardiomyopathy, pericarditis and pulmonary embolism can lead to development of AF.

Brief episodes of AF last from a few minutes to a few hours whereas in chronic AF, the atria fibrillate all of the time. Chronic atrial fibrillation reduces the pumping capacity of the heart and might lead to its failure. In many cases, patients are not even aware that they suffer from atrial fibrillation. Symptoms of AF are dizziness, fainting and fatigue. The person suffering from atrial fibrillation is likely to experience shortness of breath and angina pain. Heart palpitations and chest discomfort are other symptoms of atrial fibrillation.

Abnormal heartbeats are felt by taking the patient's pulse or with a stethoscope. An electrocardiogram and echocardiography aid in assessing the heart's rhythms. A holter monitor records the heart's rhythm over a period of about 24 hours to detect any intermittent AF. Treatment for AF is geared towards restoring normal heart rhythm, controlling the heart rate and preventing blood clots. Drugs to slow down the rapid heart rate such as digoxin, beta blockers, amiodarone, sotalol, flecainide, procainamide and quinidine are used in the treatment of AF. Atrial pacemakers may be implanted to regulate the heart arhythmias. High blood pressure must be controlled. Hyperthyroidism, if any must be corrected. Anticoagulant medications reduce the chances of blood clots and strokes. Excessive use of alcohol or other stimulants must be avoided.
