supraventricular tachycardia
"I started toprol back in spring of 2004. I was switched from generic metoprolol, I was on that for borderline hbp. After 4 years on that I developed racing and very irregular heart beats the toprolxl did nothing. they got even worse. My doc took me off saying it was side effects of both drugs. I immediately improved. I still have them but not as bad. No cardiologist has told me what was wrong. I have a really bad back. In 2011 I got an epidural at T4-5 and that completely cured my rapid and irregular heartbeat for 3 years. There are 8 nerves besides the vagas nerve that go to the heart, they are part of the autonomic nervous system. They all come off the spine at C4-5 to T4-5 I have severe stenosis at all those levels."
