I had ASD surgery in May 05 and have been suffering recurring atrialfib since. I've been hospitalized dozens of times with it and had cardioversion. I took Amirodrone for about six months but suffered bad side effects to that drug and it was the only one that worked for me to stop the atrialfib completely. It gave me plumnary hipertension and messed up my thyroid, thus levothyroxine 50 mcg now and I don't think that's enough because I'm putting on weight like crazy. I'm on 100mg of Tambacor now and I get so dizzy I feel like I'm going to faint, plus I have headaches every day. Isn't there something else out there that would work and not make me feel so bad?
Underlying 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 of atrial fibrillation or flutter occur in the setting of a heart attack or soon after surgery on the heart.
Some Atrial Fibrillation drugs can cause tremors. If drugs are not working you might ask doctor about:
Electrical cardioversion which restore normal heart rhythm with an electric shock, when medication doesn't improve your symptoms.
Or Radiofrequency ablation may be effective when medications don't work. In this procedure, thin and flexible tubes are introduced through 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 to block abnormal electrical pathways.
Or Surgery can be used to disrupt electrical pathways that generate AF.
Or Atrial pacemakers can be implanted under the skin to regulate the heart rhythm.
Many people with atrial fibrillation have no symptoms and are unaware of the abnormal heart rhythm. The most common symptom of atrial fibrillation is palpitations, an uncomfortable awareness of the rapid and irregular heartbeat. Other symptoms of atrial fibrillation are caused by the diminished delivery of blood to the body. These symptoms include dizziness, fainting, weakness, fatigue, shortness of breath, and angina (chest pain due to reduced blood flow to the heart muscles).
American Heart Association recommends aggressive treatment of this heart arrhythmia.
when and what were your last labs? perhaps your tsh has been lowered too much and you are hyperthyroid at this point. do you have copies of your lab reports?
As far as the allergies...I too am allergic to sulfa based drugs, (among lots of other things) but as long as the doctors are aware of this when prescribing and I read labels, I have had no problems...
