[|Human|] I have started taking lisinopril for high blood pressure two days ago. I was taking metropolol but I have diabetes and my doctor thought it was better. My heart rate seems to be up as high as 100 from my typical 70-80. Could this be caused by the lisinopril.
[|AI|]  Greetings. Welcome to Chat Doctor, and thank you for your question. I understand your concern. Lisinopril is an angiontensinogen converting enzyme inhibitor (ACE-I) and is effective and safe in lowering the blood pressure, but no effects on heart rate whatsoever. Normal heart rate is between 60 and 100 beats per minute. This increase in heart rate you are experiencing is rather from discontinuing the metoprolol, which has heart rate-lowering features. If this is a worrisome happening to you and produces any symptoms, then you can discuss with your cardiologist about the possibility to put you on a Chat Doctor.  I hope I was helpful with my answer. Take care. Kind regards.
