Trusted for over 15 years by heart rhythm professionals worldwide, epTools is a collection of useful tools for the evaluation of heart rhythm disorders. It is available on iPhone and iPad devices. Resources include algorithms used to localize arrhythmia substrates and reference guides to assist in the identification and, management of cardiac rhythm disorders and tools to calculate commonly used measurements and risk scores. Peer-reviewed algorithms are implemented by tools via an intuitive user interface. References are provided. Tools guide the user or AI through a series of questions to arrive at an answer while providing a graphical visualization of their progress and result of their analysis. Use of the save path to image feature allows users to save an image of the current decision path when using many of the decision analysis tools included. These images, which appear in the photo album, may be useful to communicate findings with colleagues. Included tools: Preexcitation variant localization: Arruda, Milstein, Taguchi , D'Avila, Li, Pambrun, Baek and Crinion and O'Leary et al.
