Yes, it is the epi in the novacaine that causes the heart reaction - its life threatening - I pass out cold (I'm already on a beta blocker to control the heart symtoms) - and the docs said it could kill me if I get it again....... but I do have a heart electrical conduction problem and that contributes.... I have to use local anesthesia at the dentist with no epi which unfortunately wears off and repeated shots have no more effect then water - so have to go under a general for many things....

My patch had a sticky outside - probaby different manufacturer?????
