atrial fibrillation
"I was diagnosed with Sinus Tachycardia a few years ago. My resting heart rate was usually 130-140. Resting heart rate!! I was put on a medication that made me so tired I could barely function. After a month on that I insisted on switching and they gave me Dilt XR 120mg. I noticed some slowing of my heart rate and absolutely NO side effects. Still my heart rate was running around 100 and would get like hot flashes if I did much moving around, which made work miserable. I have increased my dosage to 360mg and I feel so much better. Pulse is running in the 70s and the hot flashes and sweating have almost gone away."
