First time posting here, I have a question... I have had adverse effects after I was given nitro and adenosine, nitro was given in an ambulance and triggered a very bad tachycardia, it reached my max HR. Also before starting a stress test I was given adenosine and did the same, Max heart rate and blood pressure dropped, I ended on the floor. The doctor that did the stress test told me he never saw this happened before after the medication. Those events were before my diagnosis of autonomic neuropathy/pots.
Ok Now I'm seeing a new cardiologist and wants me to take metoprolol with diltiazem, but after doing some research I have found out that diltiazem is also a vasodilator. Should I be concerned? I mean I don't want to challenge the doctor expertise and experience at all. The reason for the meds change is because I'm taking the short-acting metoprolol and I'm still having symptoms and I can only tolerate 25mg twice a day.
Thank you in advance .
