My grandma is 62, and it has been twice now, about one week apart, that she has an episode where she experiences some rather severe chest
pain, tightness,
and pressure
and tingly weak arms, and blacking of edges of vision. She goes unconscious while still sitting up, her eyes go up in her head, her muscles stiffen, her jaw drops down, and she vomits in spurts,and at the time that the EMT got there (so not during the attack) her pressure was 111/64, and she had some arrhythmia.
