arrhythmia
"This drug is finally allowing me to live life again.  After 3 ablations, 2 Cardioversions, and numerous anti-arrymithic drugs, I am able to exercise without gasping for breath.
My Electrophysiologist  put me on the drug saying only 5 months:  I take 200mg 2 times a day for the first month, and then it will be 1 a day for four months.  The last ablation was quite extensive, so the heart needs help for 5 months.

He explained that this drug has so many potential side effects, but after 2 weeks the only problem I have is constipation.  I can deal w that!"
