Lyn,aspirin is not supposed to be used as treatment for AF in place of warfarin.
If he doesn't want to take "rat poison" whuch needs regular blood tests and interacts with a lot of other medicines, there are newer drugs which NICE has now approved , such as Rivaroxaban
if he has AF it must be treated, but not with aspirin. Get him to talk to his doctor.
