Can being overweight be related to palpitation and dizziness?
Patient: I had a palpitation yesterday and then felt very very dizzy.  It lasted all of 5 sec.  I went to urgent care.  They took my BP (167/94) and my heart rate was 101.  I am on Lisinopril/HCTZ (20 mg/12.5).  My BP last month was 128/78 and my heart rate is usually in the 70's.  The doctor said the EKG looked ok but my heart was beating a little fast.  He said I should follow up with a cardiologist, which I am going to do.  He said it was difficult to determine what happened.  I don't smoke, I am overweight, I drink very little caffeine.  Any ideas? Doctor: Hello!Welcome and thank you for asking on HCM!I passed carefully through your question and would explain that your symptoms could be could be related to a cardiac arrhythmia. Of course, being overweight, drinking coffee and smoking can trigger this clinical situation too. But, I would recommend performing some tests to investigate for cardiac arrhythmia, before concluding that nothing serious is going on: - a cardiac ultrasound- an ambulatory 24-48 hours ECG monitoring- thyroid hormone levels for thyroid dysfunction- complete blood count for anemia- blood electrolytes for possible electrolyte imbalance. If all the above tests result normal, there is nothing to worry about. Reducing caffeine intake and avoid smoking will improve your situation too. Hope you will find this answer helpful!Kind regards, Dr. Iliri
