This calculator is designed for healthcare professionals to determine the corrected QT interval (QTc) based on the patient's heart rate. It aids in assessing cardiac health and identifying potential heart-related issues.
All calculations are strictly based on the Bazett's formula: QTc = QT / √(RR interval). For more information, refer to this authoritative source. All calculations are based on the formulas and data provided by this source.
Where QT is the measured interval in milliseconds, and the RR interval is derived from the heart rate.
To calculate the QTc, enter the QT interval and the heart rate. The calculator will compute the RR interval as 60 divided by the heart rate, then apply the Bazett's formula to find the QTc.
The QT interval is a measure of the time between the start of the Q wave and the end of the T wave in the heart's electrical cycle.
QTc is used to assess the risk of arrhythmias. An abnormally long QTc can indicate a higher risk of dangerous heart rhythms.
The RR interval is calculated as 60 divided by the heart rate (in bpm).
Consult with a healthcare professional for a thorough evaluation and appropriate management.
Yes, different formulas like Bazett's, Fridericia's, and others may give slightly different results for the QTc.
