I am so sorry this happened to you. About 5 or 6 yrs ago I had an incident where I went to an Ear, Nose and Throat Dr. and he sprayed lidocaine with epinephrine up my nose. I had had some light nosebleeds after a fire we had at our place in Alaska, anyway he was checking for possible polyps. About 15-20 min after he sprayed it, I went into a-fib. When I called the office they told me it was probably not the lidocaine but instead was a reaction to the epinephrine. It landed me in the ER that night and since that single incident, I've tried to stay away from both. Incidentally, after my ablation for a-fib 15 mo. ago, I've started having short tachycardia episodes (10-30 min) and my EP has told me to take a "beta-blocker in a pocket" and it has, thank God, helped to shorten the episodes.
My EP put me on a 30 day event monitor......so far, so good, no SVT issues. I'm hoping the lidocaine reaction was a one time unusual occurrance. Hope you all have a very Happy New Year 2012!
Thank you all for your responses. I will be going to see my EP tomorrow and will let you know how it goes.

It is really important that you find out what is causing what.
It's correct that local anesthetics contain both lidocaine and adrenalin (epinephrine). They both can have effects on the heart, adrenalin has an obvious effect and lidocaine is actually an antiarrhythmic drug (class 1b sodium blocker) which may have proarrhythmic effects.
The problem is - adrenalin is added to prevent the lidocaine from having systemic effects, the blood vessels are constricted. If you have reactions towards lidocaine, choosing the one without adrenalin would be bad.
That said, they add quite a lot of adrenalin to local anesthetics and this may easily trigger arrhythmias..
Once when I got tooth anesthetic, I began trembling. I don't know what it was, but Im know that I don't tolerate epinephrine or adrenaline. Since that time I always ask such medication which does not cause trembling or tachycardia.
I would ask for Marcaine, it works longer, although it takes longer to numb up. My dentist gives me my shot and see another patient, by the time he got back to me I was fully numb. and the numbness last for 8 - 12 hours. I am highly allergic to lidocaine it puts me into anaphylactic shock, I have an epipen but sa that I don't have to use that I just make sure everyone is doing their job and I always wear my medic alert bracelet. I was given the lidocaine in the ER for sustained v-tach hope this helps
It probably isn't the lidocaine, it's the epinephrine that is in the lidocaine. You can ask your dentist to use an anesthetic without epinephrine, I have had tons of dental work and always ask for that. Dentist doesn't mind at all and I've never had any problems. It doesn't last as long but if you start to feel anything while they are working the dentist will just give you more. I have done fine with it.
I had this dilemma this past summer. I'm not sure what the dentist uses, but I too was having root canal/crown work going on. My heart always begins to race when they deaden the area. So, at first we tried the one without epi...it would not go dead enough. So finally after 3 weeks and 4 visits, I took my atenolol before I went in (per my doctor's orders) and a full 0.25 xanax. I got pretty shaky for a while but it passed quickly and 3 hours later, I was done. My dentist is very patient and was very understanding. I do have the epi free shots with fillings and it works well.
Oops, meant to say lidocaine in paragraph 3, not novocaine. (Wish MedHelp would let us make edits.)
I doubt the lidocane has hurt your heart in any way....:)
