How worrisome is tachycardia?

I went to my doctor the other day to get checked for something else and while I was there he listened to my heart - I have a family history of heart disease, my dad died of 2 heart attacks at 58, and I'm 51 and overweight - which I am working on, but have a ways to go. On the plus side I'm a non-smoker. He said he heard some tachycardia and has referred me for an EKG, a physical and blood work. I have a job that can be physically demanding and my daughter is worried that something will happen to me if I work too hard or get too drained out. Fortunately I have good insurance and can take care of my health and do what my doctor wants, but is there anything I should be worrying about in my day to day life?

I have a good support system between my children who love me very much and want the best for me and my longtime boyfriend who is supportive of what I need to do to be healthy. In the years he and I have been together he has never nagged me and always reminds me of how much he wants me and no one else. He just tells me that I can only make changes if I want it for myself.

Listen to your daughter. Children have a sixth sense about their parents. I speak from personal experience. Its great that you are working on your weight and don't smoke, but why don't you try something relaxing such as yoga or t'ai chi. Both these are very relaxing and teach your body and your mind to find inner peace. In additiion, try not working so much, and try not to worry about it. If you become that anxious about it, perhaps you need an anti-anxiety drug to help you cope. Make sure you have a good support network around you, esp when your not up to dealing with things. EXERCISE REGULARLY. With what I have, strong recommendation. Biggest thing is listen to your body, your mind and your daughter. Wtih a combintation like that, you can't go wrong.

Hi, don't worry too much in advance.

Tachycardia is basically a rapid heart rate (above 100 beats per min) and could be caused by anything from you being nervous, stressed to an overactive thyroid gland and a heart arrythmia. Treatment depends on the reason. Until you know more exercise (30-60 min/day) and a healthy diet to keep your cholesterol at a good level is always a good idea.
