Angina Pectoris
the name first given by Dr. Heberden in 1768, and since then universally adopted as the designation of a very painful disease, called by him also a disorder of the breast; by some others, spasm of the chest, or heart stroke, and popularly breast pang. It is characterized by intense pain in the præcordial region, attended by a feeling of suffocation and a fearful sense of impending death. These symptoms may continue for a few minutes, half an hour, or even an hour or more. During the paroxysm the pulse is low, with the body cold, and often covered with clammy perspiration. There are several varieties of it: an organic and functional form; and again a pure or idiopathic and a complex or sympathetic one have been recognized. Angina is produced by disease of the heart.
