kathy,
Overall the biggest risk of
atrialAtrial fibrillation/flutter
Atrial myxoma
Left atrial myxoma
Right atrial myxoma fibrillation in most people is the risk of stroke associated with the stasis of blood in atrium from the fibrillation. This risk is decreased by the used of anticoagulants. The overall stroke risk associated with fibrillation is determined by a number of factors but in all comers is decreased by coumadin and aspirin. In patients with higher risk (which your relative would qualify) coumadin is more effective than aspirin, but aspirin is still very helpful. Risk means exactly that, there is a risk of something happening. So I wouldn't say it is ineveitable, but more likely.
84 is not old for cardioversion. However, cardioversion would not be performed if a patient will not take coumadin as there is still a high risk after performing the procedure.
Generally, if your relative has no symptoms and their heart rate is controlled, there isn't a specific reason to get them out of fibrillation. I would however, look very closely and try to convince them to take anticoagulation to decrease the stroke risk. A stroke is a devastating event especially in the elderly.
good luck
I lost my mother to SCD while she was in afib
They immediately took him off Coumadin and have told him to never take it again.
He's still with us!! Unfortunately, he has esophageal cancer now...
Coumadin gives me pause due to our experiences. I should think the aspirin would be the better bet. Perhaps fish oil. Never "that ole rat poison" as my dear departed Grandpa used to call it.
