Post cardiology consultant Dr. Douglas Zipes replies:

“Heart pounding, or palpitations, can be due to simple premature beats or may signal something more seriously wrong with your heart rhythm. I always try to establish the cause of palpitations and would suggest you consult a cardiologist or electrophysiologist. You can wear a miniature ECG recorder for a month or more to document what is going on. Then, you can make decisions about what to do.”
