Unfortunately I'm being vague because the ME couldn't draw a conclusion. I've had three doctors read it to make sure I'm not missing anything (including the cardiologist I saw as a result), and they've all said, "It says her heart muscle just died, for no clear reason. It speculates about a heritable cardiac channelopathy, which is why you and your brother needed cardiac ultrasounds and stress tests, but ultimately they don't actually know why her heart died." It's as close to a diagnosis as we'll ever have.
