Hi, I went to the Emergency room this morning after having palpatations for over 10 hours. They did an ekg and some blood work and chest x-rays. All came up clear. I am still feeling the palpatations and they are no better. I am really nervous. What could be going on? -Mantha    By the way they occur about every 15-20 seconds
If you have had the symptoms evaluated and found no underlying heart disease or dangerous rhythm, the primary concern is to relieve your symptoms and anxiety. Sometimes a rhythm that is not dangerous feels just as bad and is demanding of your attention. So you may still need some more information to really get control. My normal course is to get a long term recording of heart rhythm to compare to the symptoms that you have. There are several techniques that can be arranged through your doctor. Just trying medicines to see if they help generally doesn't. In the interim, avoid stimulants like caffeine, theophylline or guanine as well as decongestants, blue cheese. Generally, avoid alcohol but especially dark beer and heavy, red wines.
