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

Corrects the QT interval for heart rate extremes (choose from Bazett, Fridericia, Framingham, Hodges, or Rautaharju formulas). Calculates maintenance fluid requirements by weight. Predicts 6-week risk of major adverse cardiac events in patients with chest pain. Coma severity based on Eye (4), Verbal (5), and Motor (6) criteria.

Estimates GFR in CKD patients using creatinine and patient characteristics. Corrects the QT interval for heart rate extremes (choose from Bazett, Fridericia, Framingham, Hodges, or Rautaharju formulas). Calculates ideal body weight (Devine formula) and adjusted body weight.

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.

Worried about QT interval prolongation? 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.

2025年1月14日 · With our QTc calculator, you will be able to perform a correction of QT interval for your patient’s heart rate. In the text below, you will learn how to calculate QTc using Bazett’s formula and other equations (e.g., Fridericia, Framingham).

Predicts risk of QT prolongation greater than 500 msec in hospitalized patients. Launched during COVID-19 crisis. This score was derived and internally validated for hospitalized patients, and may not predict outpatient risk of QT prolongation as accurately (but has not been studied in this population). Please fill out required fields.

The calculator will then provide you the QTc-intervals for five established correction formulas (i.e. Bazett, Friderica, Framingham, Hodges and Rautaharju). Based on the correction formula you wish to use the calculator will provide you the probability of LQTS for this specific patient with this specific measured QT-interval.
