My husband (age 56 a smoker) suffers from very high blood pressure (for example 186/98). He has been having episodes due to stress And even mild exersize such as climbing stairs or lifting a 20 lb box. He can feel it coming on and he knows its time to stop, loosen his belt, and take deep breaths. If he is unsucsessful in calming his heart rate down he will pass out and become unconcious. His eyes will roll back and pee on himself. Its very scary. Whats going on?
