In 1674, John Mayow gave the earliest account of constrictive pericarditis: “the heart was nearly covered by cartilage, adherent to its interior so that blood could scarcely enter.” Richard Lower accurately described tamponade in 1689: “a profuse effusion oppresses and inundates the heart. The walls of the heart are so compressed by the fluid circling everywhere, so that the heart cannot dilate sufficiently to receive the blood, then the pulse becomes exceedingly small, thence succeed syncope and death itself.”1 Franz Schuh did the first successful pericardiocentesis in 1840; Churchill performed the first pericardiectomy in the United States in 1929. Claude Beck described his triad of findings in tamponade in 1935. In 1954, Edler demonstrated a pericardial effusion by ultrasound, and in 1971 Spodick described the EKG findings associated with pericarditis.1,2
