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.

iPacemaker Device is an independent, multibrand technical and educational reference for electrophysiologists, hospital device technicians, and medical-device company specialists working with cardiac implantable electronic devices. Explore information on more than 7,000 pacemakers, ICDs, CRT devices, cardiac monitors, and leads from 60 manufacturers. TECHNICAL DATA Review device specifications, physical characteristics, dimensions, diagnostic features, and programming parameters. CONNECTOR HEADERS Examine connector layouts, port types, lead configurations, and documented tool specifications. Find device records with compatible connector-header characteristics and explore CSP configurations. MANUFACTURER ADVISORIES Access technical notes and safety communications included in the database and organized by product. MRI DOCUMENTATION Explore manufacturer-published MRI conditions for hypothetical device-and-lead combinations. This educational reference does not determine MRI eligibility for an individual patient or implanted system. ALGORITHMS Review more than 70 manufacturer-specific algorithms organized by manufacturer and technical or clinical scope. ANALYTICS Explore descriptive charts based on information contained in the dataset, including device longevity and survival data. Analytics do not predict the performance of an individual implanted device or recommend device selection. COMPARE Review specifications, programming options, longevity charts, and survival curves across multiple device records without generating treatment or device recommendations. Some content and features require a subscription. iPacemaker Device is intended solely for professional education and technical reference.
