Does a lower heart rate mean lower oxygen levels in the blood?
My husbands oxygen levels are 89% at rest during the day when they should be 90 at least and above. If it drops lower at night, that in itself could cause heart damage and damage to other organs. I'm wondering whether Bisoprolol and Amiodarone have caused this by slowing his heart rate right down. Would anyone have any information on this, please?
Incidentally, when his heart was racing in AF his Oxygen levels were around 95%.
