Question: I was resting in my recliner watching TV. Suddenly, while sitting I lost consciousness. My wife called 911 and did CPR. At the hospital I was put into ICU and intubated and placed on a ventilater for 5 days because I was in a coma. I woke up and my BP was within normal limits while on the vent. The physicians discharged me in 10 days. They did many tests and all were within normal limits except SODIUM AND LACTIC ACID. The MRI was not quite normal and showed fluid around the brain. When I was discharged the physicians told me they did not find anything wrong. I am 72-years old,of normal weight, eat properly and exercise. However, because my wife has hypertention and checkes her BP daily I have also done so this past year. My BP runs Systolic between 94 and 80 and diastolic between 64 and 54. I do not know what to do. I had no warning. My email address is YYYY@YYYY . My name is XXXXXXX XXXX
