A-Fib Tacacardia

[Tonya__0]

  I am a 36 year old female, who was dignoist with A-Fib Tackacardia a few months ago. My pluse rate was 148, my colesterial is 140 and I have an extra heart beat. My doctor checked my thyroid and said it is under active he put me on covera 360mg one time a day.He told me no cafine and to try to avoid stress.The medicine has help with my heart problems. He told me my heart problem was prety seirous, and that I was headed for a stroke.He all so said that it was hareditary.
     I have not been able to find out any information on this subject.
  Ever since I have been taking my heart pills I have been totaly exhausted.
  I don't have engry to do anything. I can run 20 feet and be out of breath.
  I can not walk very far with out having to rest. I had more energy before they fixed my heart problem. The doctor keeps telling me my body has to get use to the medicin. It has been four months so for and it is not getting any better. It seems like every time I go back for a check up all he does is increase my medicne dosage. I am not on anything for the hypothyroidism.
     I can not excrisize or anything, I have cramps in the calf of my legs,
  and I stay so tired that my arms and legs feel like jelly. My husband and kids also that I am very cranky and moody.
    Is there any information you can give on my problems or any question I should know about that I should be asking my doctor. Please help me get my life back.
  
                                             Thank You

Dear Tonya,
I have enclosed some general information about afib.  I would suggest seeing a cardiologist (heart specialist) for help with your treatment.  Afib is a treatable condition and you should be able to feel much better.
Atrial fibrillation
Definition:
A disorder of heart rate and rhythm in which the upper heart chambers (atria) are stimulated to contract in a very rapid and/or disorganized manner; this usually also affects contraction of the ventricles.
Causes, incidence, and risk factors:
Arrhythmias are caused by a disruption of the normal functioning of the electrical conduction system of the heart. Normally, the atria and ventricles contract in a coordinated manner. In atrial fibrillation and flutter, the atria are stimulated to contract very quickly. This results in ineffective and uncoordinated contraction of the atria.
The impulses may be transmitted to the ventricles in an irregular fashion, or only some of the impulses may be transmitted. This causes the ventricles to beat more rapidly than normal, resulting in a rapid or irregular pulse. The ventricles may fail to pump enough blood to meet the needs of the body.
Causes of atrial fibrillation and flutter include dysfunction of the sinus node (the "natural pacemaker" of the heart) and a number of heart and lung disorders including coronary artery disease, rheumatic heart disease, mitral valve disorders, pericarditis, and others. Hyperthyroidism, hypertension, and other diseases can cause arrhythmias, as can recent heavy alcohol use (binge drinking). Some cases have no identifiable cause. Atrial flutter is most often associated with a heart attack (myocardial infarction) or surgery on the heart.
Atrial fibrillation or flutter affects about 5 out of 1000 people. It can affect either sex. Atrial fibrillation is very common in the elderly, but it can occur in persons of any age.
Prevention:
Follow the health care provider's recommendations for the treatment of underlying disorders. Avoid binge drinking.
Symptoms:
     sensation of feeling heart beat (palpitations)
     pulse may feel rapid, racing, pounding, fluttering,
     pulse may feel regular or irregular
     dizziness, lightheadedness
     fainting
     confusion
     fatigue
     shortness of breath
     breathing difficulty, lying down
     sensation of tightness in the chest
Note: Symptoms may begin and/or stop suddenly.
Signs and tests:
Listening with a stethoscope (auscultation) of the heart shows a rapid or irregular rhythm. The pulse may feel rapid or irregular. The normal heart rate is 60 to 100, but in atrial fibrillation/flutter
the heart rate may be 100 to 175. Blood pressure may be normal or low.
An ECG shows atrial fibrillation or atrial flutter. Continuous ambulatory cardiac monitoring--Holter monitor (24 hour test)-- may be necessary because the condition is often sporadic (sudden beginning and ending of episodes of the arrhythmia).
Tests to determine the cause may include:
     an echocardiogram
     a coronary angiography (rarely)
     an exercise treadmill ECG

Treatment:
Treatment varies depending on the cause of the atrial fibrillation or flutter. Medication may include digitalis or other medications that slow the heart beat or that slow conduction of the impulse
to the ventricles.
Electrical cardioversion may be required to convert the arrhythmia to normal (sinus) rhythm.
Expectations (prognosis):
The disorder is usually controllable with treatment. Atrial fibrillation may become a chronic condition. Atrial flutter is usually a short-term problem.
Complications:
     incomplete emptying of the atria which can reduce the amount of blood the heart can pump
     emboli to the brain (stroke) or elsewhere--rare

Calling your health care provider:
Call your health care provider if symptoms indicate atrial
fibrillation or flutter may be present.
