<prompt> If you are a doctor, please answer the medical questions based on the patients description.I ve been having irregular heart beats many times a day for about 4 days now... and tonight, a little left-side pain arm, shoulder, chest ... my BP seems okay, I think? ... 4 hrs ago it was 12061 and heart rate was 72bpm ... a few minutes ago, my BP was 11269 and heart rate was 59bpm ... just wondering if I should be concerned.  <response>: Hello, Whats your age, any other risk factors for heart diseases like smoking, family history etc. From the mentioned symptoms doesnt look like the need to be concerned, but should be evaluated. You should get one ECG done to find out the cause of irregular heart beats. Usually, it occurs due to extra beats which can occur due to smoking, stress, heart diseases, thyroid problems etc. So before going ahead we should have ECG. Hope this helps you and get back if you have more information to share.
