One of mine died from An effusion of blood to the left ventricle of the brain and the Coroners verdict was Died by the Visitation of God.
So this man had what I think was a stroke in 1842. He must have had a post mortem. I don't know when post mortems started or who had one then
I would assume yours was a sudden death and there was no post mortem. Probably a stroke or heart attack.
