Hospitalized with Tachycardia, and now am scared...is this really serious?

I do have Panic Disorder and they said my white blood cell count was high, so I was hospitalized for a few days and on potassium and antibiotics. I was put on a heart monitor, and they didn't see anything wrong, only a high heart rate. My concern is that they didn't monitor me doing any sort of physical activity (I was lying in bed in the whole time). What got me into the hospital was when I had a hard palpitation when walking up a steep hill and my heart rate went up to 160 at the ER. Now I am terrified to do any physical activity, especially walking up that big hill again, which I have to do to go to class.

PLEASE HELP!!!!

Please follow up with a cardiologist, explaining what you have here, and your concerns going forward. If the appointment is too far off in the future, I'd recommend going to Urgent Care, and getting a referral.

You can monitor your heart rate yourself with a choice of different devices. This link will show you some of what's available:

By monitoring your own HR, you can see if you go into a tachycardic state, and try to relax. Getting a wristband-type monitor may work best for you.

One thing: Have you gone on any new medications recently? Medication side effects can present as tachycardia. Please have this information when you see the doctor.

Please get the monitor, and all the best to you . . .

Tachycardia can be dangerous. You should call your cardiologist and ask if you have any restrictions/limitations and let them know your concerns. They'll pull your chart and let you know. Don't depend on us here to answer such an important question. Please be on the safe side and give them a call. They won't mind. Your episode could have been a fluke too. Good luck.

I would go see a heart doctor after you get out and also I think that the antibiotics should cure your tachycardia if it has any thing to do with your increased WBC count because if your WBC is elevated that means that you have an infection of some sort. your white blood cells are what helps fight infections so when you get sick with a cold or anything else your WBC count will go up.
