11 things about epTools

1. Localization of ischemic ventricular tachycardia: Three algorithms are provided (based on Miller et al, Segal et al and Andreu et al) to assist in the localization of exit sites for ventricular tachycardia in the setting of single and multiple myocardial infarction based on findings on 12-lead electrocardiograms during ventricular tachycardia.

2. 5-yr risk of SCD in HCM (O'Mahon et al)and 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), 1-4 year mortality in 1° prevention ICD placement (Bilchick et al, SHOCKED), Shanghai score (Brugada Syndrome), VT prediction in ARVD/C (Cadrin-Tourigny et al.), Suspicious Index In Lyme Carditis (SILC), PADIT infection and ABC-VT Risk Score calculators.

3. 8 tools are provided to differentiate right from left ventricular (aortic cusp) outflow tract arrhythmias via calculation of the QRS-RVA Interval the V₂S/V₃R Index, TZ Index, V₂ Transition ratio and the R/S-wave Amplitude, R-Wave Duration, R-wave amplitude, V₂QRSI40 and RV₁-₃ indices.

4. Localization of idiopathic ventricular tachycardia and premature ventricular contractions via ECG findings: The Ito,Park and Enriquez et al algorithms assist in the localization of ventricular ectopic activity and tachycardia.

5. Tools to differentiate SVT from VT using 12-lead electrocardiogram features utilizing the Brugada, Verckei and Moccetti et al algorithms.

6. Tools for CHADS₂, CHA₂DS₂VASc and ATRIA stroke risk, HAS-BLED bleeding risk scores, QT correction heart rate (Bazett or Fredericia, Hodges) and left bundle branch block (Bogosian and Yankelson et al) and a CL to bpm interconverter are provided.

7. Resources include algorithms commonly used to localize arrhythmia substrates and reference guides to assist in the identification of clinical conditions involving abnormalities of cardiac rhythm.

8. Localization of atrial tachycardias: Algorithms provided (based on Ellenbogen et al and Kistler et al) assist in the localization of ATs from 12-lead electrocardiogram.

9. Tools to assist with diagnosis of preexcitation variants, J-wave syndromes and entrainment site localization are included.

10. 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.

11. Localize accessory pathways using algorithms of Arruda, Milstein, Taguchi , D'Avila, Li, Pambrun, Baek and Crinion et al and differentiate WPW from FVF using O'Leary et al.
