atrial fibrillation
"Atrial fibrillation due to chemotherapy. After lisinopril - metroprol and losartan I started on this - AND I LOVED IT - dizzy at first but it worked itself out after few days - heart rate was way to low at first but resolved itself - just as it all worked out and I went for my first bike ride I developed a rash - stomach - back - neck - legs then buttocks so on day 4 I'm stopping.  Bummer."
