Thanks for posting your query.
There is diurnal variation in blood pressure during whole 24 hours.
Blood pressure is lowest at 3:00 AM in early morning and it again start rising .
So blood pressure at evening time is always higher than morning blood pressure.
You should take metoprolol
as advised by your treating doctor and keep in touch.
Fall in pulse rate is due to metoprolol and is is its inherent quality.
You should considered your blood pressure variation as normal and continue with the prescribed medications.
