71 yr old female, treated for high blood pressure with beta blockers, water pill, .her heart rate is usually in the mid 40s . Migraine? For the last month. Ct scan of her head came back ok, ekg is ok ( except the low rate) . Seems more forgetful the last few weeks, and can t walk too far without stopping to rest briefly . Dizzy and nauseous the last few days. Dr recently upped her beta blockers as her pressure was a bit high. My concern is the low heart rate is causing problems. Was 41 this am.
