TīmeklisAnomogram for calculating venous shunt has been devised. The details of the derivation of the shunt formula according to which the nomogram is prepared have been … TīmeklisReference. The QT c calculator is designed to compute the corrected QT interval, which is an estimation of the QT interval when a heart is beating at a rate of 60 bpm. Determining the corrected QT interval can allow practitioners to compare QT values over time at a variety of heart rates. It can also help doctors to better identify which …
