How can I find out what is causing me to have heart arrhythmia?

Earlier this year, I kept feeling as though I had constant palpitations. It was not only annoying, but disconcerting. So, I went to my physician and she had me go through a battery of tests - ECC, Holter monitor, you name it. Results? Nothing discernable. We still don't know why I occasionally get those darned palpitations, and they're not in my head!

So, if you're this concerned about what you're feeling - and I would be, too - go have it checked out. I hope it doesn't turn out to be something serious, but something that you can finally put a finger on and get under control.

Do you feel the lightheadedness after any particular activity, or are you feeling any particular stress, lately?

There are a number of tests that can be done to diagnose an arrhythmia, as there are several different types of heart arrhythmia.

Many of these tests are non-invasive, and require you to see a specialized doctor (a cardiologist or electrophysiologist). Have you asked your physician about this? Was s/he concerned? Either way, it would be a good idea to have a test done, to rule out anything serious.

Please review the Mayo Clinic's Arrhythmia Diagnosis site, and feel free to ask any follow-up questions.
