"I have had to use this medication several times due to rapid heartrate. The highest my heart has increased is 260 bpm. Anytime I have had to call 911 they insert and IV and this medication is pushed very quickly through the IV. I do feel a good bit of pressure in my head. But it doesn&#039;t hurt in any way. They ususally have to do it twice for my heart rate to convert. It always works. It&#039;s not a problem once you understand that you are literally using a CTRL, ALT, DELETE technique. I have never had a side effect to this. My only effect to my experiences are....exhaustion for just having ran a marathon without actually have to run 26 miles.  :)"
