arrhythmia
"I have been on this medication for 11 years. It regulates the PVC%u2019s and PAC's, and slows the PSVT episodes that I get 1-2 times per year. Before this medication I always had irregular heart beats due to PAC's and PVC's and I was always tired and weak. As soon as I started using this medication I had a lot more energy. The only down fall, is that I always feel hot/humid even when its not hot/humid."
