Quinidine for Arrhythmia Reviews

"My age :83. Condition of arrythmia since the 1960's when my doctor prescribed Quinidine. As time went on, so-called "better medications" have been recommended and I tried many of them without obtaining the same benefits as with Quinidine. Only the Beta-blocker Metropolol is helpful in connection with Quinidine 200mg. I call Quinidine a life-saver. "


"It causes diarrhea frequently, makes you tired but it considerably lessens my arthymias as the Doctor wanted my heart to stop being shocked from my implanted ICD/ pacemaker. I'm only in the first month of taking it and if the diarrhea continues the Doctor may be taking me off of it."
