<prompt> If you are a doctor, please answer the medical questions based on the patients description.I m a 30 Indian Male, and I get both extremes of blood pressure. Recorded a high of 160110 and a low of 6845 on my digital sphygmanometer or I think that is what it is called. I also suffer from arrythmia wherein my heart rate has often shot upto as high as 138 beats per minute. For my arrythmia is was prescribed Tenormin varying doses by diff. doctors for way too many years now. Even in low blood pressure, my heart rate is often as high as 110. Any cues for me?  <response>: Hello, Regarding your concern, I would explain that it is important performing some tests in order to investigate for some metabolic disorders which can mimic this clinical scenario. In this regard, I would recommend performing these tests: - a resting ECG and cardiac ultrasound-thyroid hormone levels for thyroid gland dysfunction- blood electrolytes for possible imbalance-kidney and liver function tests - a Doppler ultrasound of the renal arteries for possible narrowing-cortisol and aldosterone plasma levels for possible a Chat Doctor. Increasing the dose of Tenor min is necessary considering your high heart rate. Hope I have answered your query. Let me know if I can assist you further.
