Thank you all so much! They kept me til early afternoon to follow my cardiac enzymes, everything was negative. They tried to do the stress test but BP was too high so settled for an echocardiogram, which is unchanged from my baseline. So, no idea what happened, but no damage or residual issues. I'm good with that! My poor Honey so wanted to drive up but I convinced him to stay home and just kept in close contact. Bless his fellow nursing students and his instructor, they brainstormed with him all day on what could have triggered this. We are so incredibly blessed to be surrounded by such supportive Christians, both on line and in person.
