<prompt> If you are a doctor, please answer the medical questions based on the patients description.I am 24 years old and i am overweight and have high blood pressure. Just in the last 4 days i have noticed my heartbeating a little bit faster than normal. I actually looked in the mirror and had seen a pulse in my neck. I am a little bit worried and had thought about going to the er but it takes forever in there. could there be something wrong?  <response>: Hello! Welcome and thank you for asking on Chat Doctor! I passed carefully through your question and would explain that an increased heart rate is quite normal in overweight persons. The visible pulse in your neck could be related to high blood pressure and tachycardia. Anyway, I would recommend consulting with your attending physician for a physical exam and some tests to exclude other possible causes that may lead to this clinical scenario: - a chest X-ray study and pulmonary function tests- a cardiac ultrasound - an ambulatory 24-48 hours ECG monitoring to investigate for cardiac arrhythmia-complete blood count for anemia-thyroid hormone levels for thyroid dysfunction- blood electrolytes for electrolyte imbalance. Meanwhile, I would recommend you to avoid caffeine intake and reduce salt in your diet. A lot of physical activity would help reduce your blood pressure and heart rate values and also help lose some pounds. Hope you will find this answer helpful! Kind regards,
