Medications to control sinus tachycardia and chronic low blood pressur
Following a successful ablation for AFib that unfortunately damaged my vagus nerve, I developed chronic low blood pressure that caused fainting, migraines, and sinus tachycardia, My cardiologist prescribed Midodrine to raise my blood pressure and Ivabradine to lower my heart rate, but my pharmacist told me not to take those drugs together since as an 86 year-old woman with a history of QT prolongation, I was at risk of developing it again. I don’t know whom to trust. Has anyone had a similar experience?

No such experience, but your pharmacist is the expert on drugs and their unwanted effects. My advice is to return to your cardiologist and tell that person what your pharmacists has said might be a problem with those prescriptions. From there, it's up to you what you do with what you learn from either expert. Perhaps your cardiologist will agree to monitor your heart frequently for the first few weeks to see if the long Q-T develops. If it turns out to be a non-issue, you get the anticipated benefits of the drugs and none of the worry or risk.
