What to do if diagnosed with tachycardia?

I'm a 21yr old female and was diagnosed about 3 years ago with having tachycardia. My doctor ran some tests and said that I should not worry about it, that everything looked alright. But my grandpa died of congestive heart failure at 67 and had diabetes, and I worry about that happening to me. What should I do to find out if there is anything to help slow my heart rate down so it does not develop into anything more serious?

You really need to discuss your options with your doctor.

However from experience, my mother was diagnosed with it as well when she was 40. She started taking Lenoxin and has been taking it ever since. She's 73 now...and still well and "kickin'."

well, i can tell you just to eat heart healthy foods and make sure to exercise everyday (not to strenous), and remember tachycardia is your heart beating about more than 100bps and you need to maybe watch your deit and junk like that. one things for sure LISTEN TO YOUR DOCTOR, his advice if followed should make you feel better!

there are different types of tachycardia
the commonest types are paroxysmal (intermittent) supraventricular tachycardia and sinus tachycardia.
you might have to undergo a test like an event monitoring to better identify which form you are experiencing.
after this is done your doctor might be able to prescribe medications to keep in under check
medications in the category of beta blockers and calcium channel blockers are commonly used for treating these
also as always it is important to avoid consuming foods stuffs with stimulants and caffeine, which makes your heart beat faster
also you should consider getting your thyroid hormone levels checked as excessive levels may cause tachycardia, this is a simple blood test.
tachycardi per se doesnt lead to congestive heart failure unless it is persistent
hope you feel better soon
