Hi. I am not a doctor or medical professional.
The medline website says that rash is one of those results of taking this drug that warrant immediate medical attention. I would contact your doctor and consider making a visit to urgent care.
Duktuazen, used for A-Fib and PSVT, can causes rash and leg-edema, low blood pressure, and dizziness.
My suggestion is start lap-swimming using a front-mounted snorkel every day for 45 minutes and you'll strengthen and tone your heart.
After a week your heart will be stronger and the electrical pathways will conduct current more effectively reducing the chance of PSVT episodes returning.
Continue this program for 2 months and your heart-rate should be down 6 points and the electrical current pathways should be working more effectively reducing the chance of PSVT episodes.
