The Bazett’s formula overestimates the QTc interval at high heart rates (>60 bpm) and underestimates the QTc interval in bradycardia (<60 bpm), and is likely to be the least reliable method of correction. This method is used in most ECG machines. Click here to zoom image. dothan endodontic associates
