My wife has been having fainting spells every month or so sometimes 2 a month, she gets these bruises in her legs, arms, body sometimes 3 inches round, and once when i check her heart when she was about to faint , it beat twice as fast for a beat or 2 and then beats normal. When she faints or has chest pains, her pulse remains around 70-80 lying down and but her blood pressure is around 127/85 or so. Her normal bood pressure while sitting is around 80/55 or so so I get excited and nervious when her blood pressure is higher laying down after the chest pains, blurry vision and numb left arm. Does she have weak veins that may be bursting.?
