The QT interval is an important ECG parameter and the identification of ECGs with long QT syndrome is of clinical importance. The QT interval is dependent on the heart rate in an obvious way (the faster the heart rate the shorter the QT interval) and may be adjusted to improve the detection of patients at increased risk of ventricular arhythmia. QTc is the QT interval corrected for heart rate
This calculatore provides QTc using Bazett's Formula, Friderecia's Method and Framingam's Formula.
