epTools 3.13

epTools is a comprehensive platform designed for evaluating heart rhythm disorders. It is a versatile app that can be used on both iPhone and iPad devices.

The platform offers a range of resources, including commonly used algorithms for localizing arrhythmia substrates and reference guides that assist in identifying clinical conditions associated with cardiac rhythm abnormalities. These algorithms are seamlessly integrated into an intuitive user interface, guiding users through a series of questions and providing graphical visualizations of their progress and analysis results.

One particularly useful feature is the ability to save decision paths as images, which can be stored in the photo album and shared with colleagues. This facilitates effective communication and collaboration among healthcare professionals.

epTools also provides access to scientific reference materials that are cited within the app. Many of these references are freely available or easily accessible for subscribers.

The platform includes a variety of algorithms for localizing different types of arrhythmias. For example, it offers algorithms by Arruda, Milstein, Taguchi, D'Avila, Li, Pambrun, Baek, and Crionon et al to localize accessory pathways and differentiate between WPW and FVF using O'Leary et al.

When it comes to localizing atrial tachycardias, epTools offers algorithms based on Ellenbogen et al and Kistler et al, as well as the De Ponti et al tool for calculating the mapping window required to identify the isthmus of an AT. The Miyazaki et al tool aids in localizing macro reentrant ATs based on pacing responses.

To assist with the diagnosis of preexcitation variants, J-wave syndromes, and entrainment site localization, epTools provides dedicated tools.

For localizing ischemic ventricular tachycardia, the platform offers three algorithms based on Miller et al, Segal et al, and Andreu et al. These algorithms assist in localizing exit sites for VT in the context of single or multiple myocardial infarctions, based on findings on 12-lead electrocardiograms during VT.

epTools also includes algorithms by Ito, Park, and Enriquez et al for localizing idiopathic ventricular tachycardia and premature ventricular contractions via ECG findings. Additionally, there are eight tools available to differentiate right from left ventricular (aortic cusp) outflow tract arrhythmias using various indices.

The platform provides two tools for differentiating endocardial from epicardial VTs, employing the MDI by Daniels et al and the Berruezo criteria.

In terms of disease assessment, epTools offers consensus criteria for ARVD/C and Short QT Syndrome. It provides risk calculation tools for various scenarios such as 5-year risk of SCD in HCM (O'Mahon et al), LQTS (1-2-3-LQTS-Risk), inadequate DFT safety margin (Hsu et al), LA arrhythmogenic substrate (Kosiuk et al, D'Ambrosio et al), 30-day mortality after PPM and ICD lead extraction (Brunner et al), and 1-4 year mortality in primary prevention ICD placement (Bilchick et al, SHOCKED). Additionally, it offers scoring tools like the Shanghai score for Brugada Syndrome and VT prediction in ARVD/C (Cadrin-Tourigny et al), as well as tools such as Suspicious Index In Lyme Carditis, PADIT infection calculator, and ABC-VT Risk Score calculator.

An CIED/electrocautery manager is also integrated into epTools, allowing users to create and share detailed preoperative plans via text or email.

Finally, the platform provides a valuable resource in the form of clinical guidelines and consensus statements.

With regards to differentiating SVT from VT using 12-lead electrocardiogram features, epTools incorporates algorithms by Brugada, Verckei, and Moccetti et al.

Additionally, epTools includes tools for calculating stroke risks such as CHADS₂, CHA₂DS₂VASc, and ATRIA scores, as well as bleeding risk using the HAS-BLED score. It also provides tools for QT correction heart rate using the Bazett or Fredericia correction formulas and for evaluating left bundle branch block using the Bogosian and Yankelson et al criteria. Lastly, it features a CL to bpm interconverter.
