my husband had a heart attack about 12 years ago, he had a stent put in then. Last year he thought he was having another heart attack, luckily he hadn t had one, but another stent was placed. Recently he has been having dizzy spells and went to see doctor, blood pressure was on the low side. Doctor did blood work which appeared to be normal. My husband then bought a blood pressure monitor he uses on his wrist a few times a day. Last night the pressure was low again. Today it is better but the monitor says it is an irregular heartbeat and pulse is upper 90 s. Should I take him to the hospital? He says he feels okay, but that he feels odd.
