Not sure what armor thyroid might result in, but I'm on levothyroxine and I was just reading the side effects, and they list: "chest pain or pressure or a fast heartbeat a heartbeat that does not feel normal". This sounds like a tachycardia or an arrhythmia to me. I am going to see my thyroid doctor and ask him if Levothyroxine could result in PVCs. Or even my hypothyroidism. |
