The Corrected QT Interval (QTc) adjusts the QT interval correctly for heart rate extremes.

The QTc calculator is aimed at determining the corrected QT interval. This is based on the use of the QT interval, as extracted from an ECG test and the pulse rate of the patient, measured in beats per minute.

2025年1月18日 · One of the earliest and most widely used correction methods, Bazett’s formula calculates QTc by dividing the QT interval by the square root of the RR interval (the time between two successive R-wave peaks). However, it tends to overcorrect at high heart rates and undercorrect at low heart rates, potentially leading to inaccuracies.

This online evidence based resource will help guide you how to measure the QT interval and calculate the QTc value with an easy to use calculator which takes into account the patients underlying rhythm, gender and age.

You can use this QTc calculator to determine the corrected QT interval (QTc) in seconds in accordance with someone's heart rate (beats per minute). The QTc calculator relies on the formulas that are most commonly used to determine a QTc interval

2025年3月17日 · Quickly calculate the corrected QT interval by just entering the QT interval duration and the heart rate.

Calculate the corrected QT Interval using our free online QTC Calculator. QT interval is a measure of the time taken for the heart muscle to depolarize and then repolarize, representing electrical systole. It is a significant parameter in electrocardiography (ECG) studies.

Calculate the corrected QT interval. 1.QT Correction? 2.QT Interval? 3.Heart Rate? The most commonly used QT correction is that of Bazett which was proposed in 1920. Unfortunately the Bazett correction overcorrects with heart rates >110 …

Learn about QT interval correction using the Bazett Equation for accurate EKG interpretation and assessment in healthcare practice.

The Corrected QT Interval (QTc) Calculator is a tool used to adjust the QT interval (a measure of ventricular depolarization and repolarization on an ECG) for heart rate. The QT interval varies with heart rate, and correcting it provides a standardized measurement to assess the risk of arrhythmias like Torsades de Pointes.
