<s>[INST] My mother is having lightheadiness and heart palpitations and sometimes her hear races. This has been over the last few days. She just checked her blood pressure and it is normal and her pulse rate is 72. Could she still have a heart attack with normal blood pressure and pulse rate? Thanks, Kelli [/INST] Hi, Lightheadedness associated with palpitations can be caused by irregularities in heart rhythm.  Heart rate and blood pressure can be normal in these cases, but it is important to know what her heart rhythm is, and what is usually done is an ECG which documents the electrical activity of the heart. It may not be a "heart attack" per se, but it is noteworthy that she may undergo tests as part of the work-up.  And I would suggest a consult with a doctor to be able to check other causes of dizziness such as a musculoskeletal problem in the neck, as well as problems in the eyes and ears which may cause dizziness, apart from a problem in the heart. Hope I have answered your query. Let me know if I can assist you further.  </s>
