Okay, my story is set in a pre-industrial fantasy setting where they have a better understanding of the workings of the body than we did because life magic lets healers "peek inside." Still, I don't want to use modern terminology for things, and I've had fun researching archaic terms for various conditions.

One I have not successfully been able to look up, though, is a term that encompassed the concept of a "heart attack" prior to the 20th century. The term apoplexy was used to describe strokes, and angina was used to describe chest pain, but not heart attacks per say.

I have a scene where another character awakens another suddenly, scaring him. Trying to think of something he'd say like, "You almost gave me a heart attack," that would work in a fantasy setting where they do know what the heart is and what it does (pump blood) but would not be using 20th century terminology. I've found all sorts of neat sites about the history of medicine and various civilizations' notion of the heart and how it worked and the causes of heart disease, but I haven't found any that give the words/terms they used.
