Are you on any medications to control your tachycardia? If you resting HR is over 100 I'd think a beta block should be tried to get it lower.
You should get a heart check-up with a cardiologist, I believe.
I was taking 150 mg of toporal but i stopped taking it because it did not seem to help my heart stay above 90 and below 120..thats normal for me..the chest pain is new.
I have been having tachycardia attacks since I was in my 30's, I am 80 now and I would just rest for a few minutes until they were over. Now I still have them and one that happened 4 years ago wouldn't stop. I wound up in the hospital where the emergency doctor had trouble stopping it but finally did. I stayed there a week having many tests and they found I have a form of leukemia. Chronic myelogenous leukemia. I still have them occasionally and have been taking Toprol, Micardis, Verapamil, Hydrochlorathyazide, Niacin, and.Omega 3. Nothings changed but I am still living! Dolores
