In this workmens compensation case, the problem is whether the plaintiff, who had a heart attack while on the job, suffered a compensable accidental injury. The trial court entered a judgment upon a jury verdict for the plaintiff. The Court of Civil Appeals reversed and rendered a take-nothing judgment because there was no showing of any strain, exertion, traumatic shock, or particular exciting mental stimulus which precipitated the heart attack. 466 S.W.2d 373. We affirm.
