What could cause heart palpitation?
Patient: I am a 23 year old male.  I started a running routine about a month ago.  I never ran much before, but I am to the point where I enjoy it now.  I also drink alot of coffee.  Three days ago, I started to feel my heart palpitate, though I feel no other symptems which would lead me to worry about a heart attack.  I worked out several times since then, and I do not feel abnormal while working out, though once I get calmed down, I feel fluttery at times.  Should I be overly worried?  I cut back on the caffeine since I started to feel the palpitations. Doctor: Thanks for your question on Healthcare Magic. I can understand your concern. Fluttering sensations, palpitations etc are commonly seen with arrhythmia (rhythm disturbances in heart). And if not treated promptly, arrhythmia can be life threatening. So better to first rule out arrhythmia in your case. So consult doctor and get done ecg, 2d echo and Holter monitoring (24 hours continuous recording of ecg). If all these are normal then no need to worry for arrhythmia or other heart diseases. Sometimes, overthinking of any thing can also cause similar symptoms. So don't think too much, relax and be calm. It's good that you cut down caffeine intake. Don't worry, you will be alright,but first rule out arrhythmia. Hope I have solved your query. I will be happy to help you further. Wish you good health. Thanks.
