supraventricular tachycardia
"I'm a 22 year old Female. (115/5'1) Long story short, I found out I had Tachycardia and experienced palpitations as well. I had extreme anxiety because of it which made it worse. I got prescribed Metoprolol Tartrate twice a day at first and it was a nightmare. It actually had like a reverse reaction on me and gave me constant flutters for a whole day. The doctor told me to take Magnesium twice a day with it and it would help and it definitely did. I eventually switched to the extended release, once a day, along with Magnesium and I couldn't be happier. I feel a lot more relaxed and normal. Had few palps still with Tartrate but not with Succinate (yet). I wanted to wait to write a review because I know I relied on reviews. Hope this helps!"
