hello and welcome to healthcare magic!!
well the blood pressure and cholesterol
levels are related and bad for your health, the low pulse rate maybe due to the drug that you are taking for blood pressure it is a beta blocker
and is known to cause low pulse rate as a side effect or the pulse rate maybe normal for your body some individuals have a lower baseline pulse rate,If your pulse rate was the same before you started the tablets. I would suggest you bring this to your doctor's attention.
