Resting pulse between 41-60 and blood pressure 140/70. can hypertension cause bradycardia ?

Not really: Not usually. It would be important to get an EGG and find your underlying rythm. Maybe there are some conduction abnormalities or issues with your Sinus node. Have in mind that if you don't have symptoms, no treatment necessary for bradyardia. Unless you have a heart rate lower than 40 and depressed ejection fraction usually <40%
