The "Bazett formula" is used for correcting the observed QT interval and is named after Henry Cuthbert Bazett who was born in England in 1885. He studied medicine and worked in Oxford and served in the British Medical Corps during World War I. In 1920, Bazett published his seminal paper on the different intervals length of the electrocardiogram recordings in a small group of healthy individuals, and proposed a formula for correcting the QT length for heart rate. Later, he moved to the University of Pennsylvania, in Philadelphia, and from 1931 until his death in 1950, he served as head of the Department of Physiology and a leader of the American Society of Physiology. Bazett's scientific work was largely concerned with temperature control, circulation, and blood volume, and he contributed greatly to the study of circulation in humans by using invasive catheterization.
