I had a heart attack 5 yrs. ago.I have 2 stents.I have been suffering with severe panic disorder for the past 2 years.I have to have a heart cath done on tuesday.I would like to know why they can put kids to sleep or use heavy sedation on the but not an adult?The last cath was a nightmare I couldn't even keep my legs from shaking from the extreme anexity and the light sedation does not work for me.Can they make special arrangements for patients like me? and do I have the choice to tell my doctor what I need.He is a new cardiologist and really dosen't know me that well.I need help to get through yet another cath and possible stent.Is there a better medication they can give me?
