ATRIAL WHAT?
Atrial fibrillation is a common abnormal heart rhythm. It is estimated that over one million Americans have this condition.
There are four chambers of the heart – two atrial (the top chambers) and two ventricles (the bottom chambers). Atrial fibrillation occurs when the atria begin to beat in a rapid, irregular rhythm.
WHY DO I HAVE ATRIAL FIBRILLATION?
All types of people get atrial fibrillation. This irregular heart rhythm can happen in patients with many types of heart disease, including, but not limited to: atherosclerosis (hardening of the arteries), congestive heart failure, hypertension, and valvular heart disease, such as rheumatic heart disease. Atrial fibrillation can even occur in patients with a normal heart.
WHAT CAN I DO ABOUT MY ATRIAL FIBRILLATION?
Episodes of atrial fibrillation can occur in either brief or persistent episodes, and in some cases become chronic (long term). Most likely, your physician will prescribed medications to convert the heart’s irregular rhythm to normal rhythm. It is important that you take your medication as instructed to prevent recurrence of the problem.
Atrial fibrillation can often cause other health problems if left uncontrolled or untreated. Because the atria are beating rapidly, they cannot empty properly. Blood can begin to pool in the “malfunctioning” atria and form clots. These clots can break free and lodge in an artery of the brain, resulting in a stroke. Remember – with proper care and treatment, the risk of stroke is greatly reduced.
Although oral mediation is frequently an effective treatment for atrial fibrillation, further treatment may be needed. If this is the case, your physician will recommend alternatives for treating your irregular heart rhythm.
COMMON SIGNS AND SYMPTOMS OF ATRIAL FIBRILLATION:
- Irregular heart rhythm felt while taking your pulse
- Heart palpitations
- Dizziness or lightheadedness
- Fatigue or exercise intolerance
- Shortness of breath
Report any of these symptoms to your physician so your treatment can be evaluated.
