I am a soon to be 70 year old male. I am taking Tribenzor 40-5-12.5 once daily, and carvedilol, 6.25 mg, twice daily. My systolic numbers are routinely in the 50 s and 60 s. My heart rate is 59/min over a 24 hour period, inc. 45 minutes of 3.8miles/hour, but resting at home is sometimes in the mid-high 30 s, and routinely in the 40 s and 50 s. Is this particular mix of drugs causing my low diastolic pressure and low heart rate? If so, you have some thoughts to change meds? Thank you.
