Agggh. Man deserves kicking. I've just written on another thread that I have some sympathy for doctors, but not much for this one. Of course there are drugs that can control heart rate - so what does he suggest, why, and what's the impact? He's right, atrial flutter is most unlikely to kill you but tension about a stroke won't help one bit - my cardiologist has me on blood thinners to protect against same. It may not be the right solution for you, but your GP doesn't sound much motivated to find solutions, just alarm you. Don't even start me on the finger. Can you get a referral to a cardiologist?
