Accurate and Model-Free QT Correction Method

In the electrocardiogram (ECG), the QT interval is one of the most important signals. The challenge in the interpretation of the QT measurement is its dependence on the heart rate (RR intervals). To normalize out this dependency, several approximative correction methods have been developed, e.g., the powerlaw formulas of Bazett and Fridericia that are still in clinical use. We have developed a new QT correction method, AccuQT, which is superior to all the existing QT correction tools in the market.
