Supraventricular Tachycardia
"I have had this given through IV 2x and each time it cause my heart rate to go up to 200 and up,  it never lowered it.  Yes I had the crazy heavy feeling (like an elephant is on my chest) couldn&#039;t breath and was hot and dizzy not good! I will not allow doctors to inject this while having an episode I get another medication that works for me.  Unfortunately adenosine doesn&#039;t!"
