I wasn?t going to post but then I thought it might help someone else. I went in to the ER once on Thursday and by the second time Friday I was there the ER called for an ambulance to come and take me to St.Vincents hospital cardiac unit. I came in once in A-fib and then I had irregular heartbeats which a nurse said was svt (super ventricular tachycardia). My heart rate kept going to 180-190bpm. It was a horrible feeling. I am small and my shirt moves with my heartbeats as it is but nothing like that. The nurses on the first visit Friday got it under control with injections of toporol but the second time it was a different shift and they didn't want to try anything. I was really upset. When the ambulance guys got there they were mad that I had laid there for 3 hours with a heart rate of 180+ without any drugs to help slow it down. They loaded me in the ambulance and started meds to try to lower my rate and to "reset" my heart back to a normal rhythm. Anything they gave me only worked short term and I went right back but they kept the toporol going so at least my rate was better. I spent 4 days in the hospital and just got home yesterday. I am on two new drugs to keep my rhythm regulated plus I am still taking toporol. The new drugs are working but they make me feel really lousy. I hope after I am on them for a while the side effects will ease off a bit. My INR was 7.1 when I got to the hospital so I had an injection of vitamin K. My cardiologist is now going to get my INR stabilized and only have my regular doctor test my blood but not adjust me. My reg. doc seems to only want to try 2.5 or 5. I am not going to let this frustrate me. I have the very best cardiologist and I trust him very much. Now that he is handling things I know I will be ok.
