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. Atrial tachycardias: Ellenbogen and Kistler et al (localization ) De Ponti et al tool (calculates the appropriate mapping window for isthmus identification) Miyazaki et al (localizes macro reentrant ATs based on pacing responses) Ischemic ventricular tachycardia localization: Miller, Segal and Andreu et al) Idiopathic ventricular tachycardia and premature ventricular contraction: Ito, Park and Enriquez et al (localization) ABC-VT Risk Score Differentiation of left vs right ventricular outflow tract sites: QRS-RVA Interval V₂S/V₃R Index TZ Index V₂ Transition ratio R/S-wave Amplitude, R-Wave Duration, R-wave amplitude, V₂QRSI40 and RV₁-₃ indices.

Discover a unique program for studying blood group compatibility! With the help of our program, you will: • Learn which blood groups are compatible with each other, and which group can be replaced in emergency situations. • Understand what will happen to the body when incompatible blood is transfused. • Get acquainted with lists of products that help thin or thicken the blood. Why is this important? Each person's blood group is innate and unchanged throughout life. The main blood classification systems: • The ABO system (four blood groups) • The Rh factor (positive or negative) Maintaining compatibility according to these systems is critically important for safe blood transfusion. • People with blood group I are universal donors. • People with blood group IV are universal recipients. Remember: according to modern standards, blood can only be transfused from a donor with an identical group. Don't miss the opportunity to understand the basics of vital information!
