Atrial Fibrillation
"I am taking Cartia XT 240 MG for atrial fibrillation. It works and I have not noticed any other side effects other than being sleepy all of the morning. I take it at 6:30 am and usually could fall asleep without much prompting. However I&#039;m not groggy and can concentrate fine. The heart is in rhythm and thats what counts."
