修正されたQT計算機
QTc Fast allows you to calculate the corrected QT on an ECG, through 4 different methods (Bazett, Fridericia, Framingham, Hodges).
Use milliseconds (ms) or values in millimeters (mm = small boxes) for absolute QT interval, and use milliseconds (ms) or values in millimeters (mm = small boxes) or bpm (beats/min) for RR interval.
Select paper speed (ECG at 25mm/s or at 50mm/s).
