I dont' have any heart problems, but I cared for my father who did. A heart rate that high is not normal, my father had many problems with that. His would race out of control, sometimes with a trigger, sometimes not. He was shocked back to normal rhythm about
10 times before anything was ever done. He had a defibrillator implant put in that did not allow his heart to go over 140 and it worked wonders for him. He stopped blacking out, his dizziness mostly went away. Due to your age, I'm not sure this would be the answer for you, but thought I would post it anyway. Also, my dad could NOT take many, many medications. Even nasal spray can increase your heart rate. Albuterol and similiar meds do speed up your heart rate, my daughter had to use it, and fanatic that I am, I read all the side effects. You really need to talk to your doc and a cardio about
this problem, and get it resolved. From what I heard from my dad, those shocks are NOT a fun thing to go through.
Just a note to Els..... I don't want to disagree with you, but many times an ER will shock someone to put a run of super fast heart rate back into normal sinus rhythym, without it being a full code. At a rate of 260, there really isn't another option. I grew up dealing with my father and his heart, so spent waaaay too much time in the ER as a child :(
I'm not procrastinating----I'm still doing yesterday!!!!
