This is a very basic question so apologies. I've just started taking Bisoprolol 5mg, the first dose yesterday, after my EP took me off Verapamil. I was absolutely freaked when even putting one foot in front of the other caused the most terrifying breathlessness, so much so I was unable to speak or move!
The EP told my GP that if I was unable to tolerate Bisoprolol due to my mild asthma or if my heart rate fell below 60 at rest, it should be discontinued and replaced with another drug I can't remember the name of.
My question is what is the most accurate way of taking your heart rate? I've never really felt Afib in my pulse or chest so how can I establish if it's below 60?
Also, is this reaction to Bisoprolol in response to changing meds and I need to give it a bit longer, or is it a reaction due to asthma? All of this is so new to me and, to be honest, I'm scared of taking Bisoprolol this morning.
Any advice/comments really appreciated. Thank you.
