I have noticed over the last few days that my resting heart rate when I get up in the morning has dropped from around 55 to 46 this morning - dropping about a couple of beats a day over the last few days. I have an appointment with my Internalist on Friday but just wondered if anyone else had experienced this type of a drop? I saw my GP last Friday and she acknowledged that my heart rate was fairly low. I am on what I understand to be a pretty large dose of Metoprolol (225mg/day) and will be asking the Internalist if this can be reduced.
