Henry Bazett
Henry Cuthbert Bazett (1885-1950) was an English physiologist.
Main area of work was the application of physiological research to clinical problems. He perfected an exact technique for studying temperature changes in circulating blood, and showed the importance of the venal comites in the pre-cooling of the arterial blood by the returning venous blood.
Eponymously affiliated with Bazett formula to calculate corrected QT interval (QTc) for varying heart rates. In 1920 Bazett related the corrected QT interval to the square root of the RR interval (the Bazett formula) independent of the relationship defined by Fridericia (1920) the duration of the QT interval was related to the cube root of the RR interval (the Fridericia formula)

Medical Eponyms
Bazett formula (1920)
Bazett formula ‘corrects’ the measured QT interval to a value (QTc) attributable to a heart rate of 60 bpm. Thus providing a QT interval value that a particular patient would theoretically have if their heart rate was 60 beats/min
