Use the QTc calculator to determine the corrected QT interval (QTc) in seconds in accordance with someone’s heart rate (beats per minute).
The QTc calculator helps compute the corrected QT interval, which is an estimation of the QT interval when a heart is beating at a rate of 60 bpm. This allows practitioners to compare QT values over time at a variety of heart rates, which helps them better identify patients who are at a higher risk of developing arrhythmias (irregular heartbeat).
The standard QT values are below 0.45 seconds for men and 0.46 seconds for women. If levels deviate significantly from these values, there is a risk the patient is suffering from heart issues.
Multiple formulas can be employed to determine QTc – Bazett, Fredericia, Hodges, Framingham
