What causes palpitations and irregular heartbeat?
Patient: As I check my pulse, I can tell my heart is skipping a beat intermittently while at rest.  There is no pain and I feel fine, but there has also been an occasional palpitation that seems to correspond with the missed beat.  I have not had a heart attack and I had a routine check-up with my internist yesterday. Doctor: Hello there. Thank you for choosing Healthcare magic . First of all I would like to ask you what is your age and sex. There can be many causes of palpitations like stress, thyroid disorders, fever, too much caffeine. Have you got an EKG done during your routine check up ? if not I would advice you to get it done to rule out any cardiac causes. Also a 24 hour holter monitoring to detect any irregular heartbeats. Get a thyroid profile done. Get a haemoglobin test done cause sometimes anemia may also lead to palpitations. I hope that answers your question. i f you ahve any other queries please feel free to write.
