supraventricular tachycardia
"I am a 20 year old female (yes, 20) and I am taking it for SVT. I take 75 mg twice daily, every 12 hours. Right after I take it, my heart rate increases and I get major anxiety. At night it's when it's worse. During the day, I'm perfectly fine. I also have chest pains and SOB, sometimes back pain. I also have heavy legs. Headaches are a definite. I am not wearing the Event Mintor to track my heart rate. It can get high, which can be scary because you don't know what could happen next. Some sleepless night and early morning wakes with anxiety. It sucks because when I have these panic attacks, I can tell when it's about to start so I brace myself. But I tell myself that Jesus is going to heal my body every day."
