I’ve been taking propranolol (a beta blocker) for a few months now, to treat my migraines. Recently I’ve noticed, that I’ve been feeling irregular heartbeats and discomfort in my chest. It also feels like my heart is beating slower than usual? Not sure how to feel about this… My doctor said my blood pressure is good, but I’m only worried about my heart rate, not the blood pressure. What should I do next? Has anyone had a similar experience to mine, and what did you do about it?
