## epTools Description
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.

Differentiate endocardial from epicardial VTs:
Maximum deflection index 
Daniels and Berruezo et al criteria

Differentiate SVT from VT:
Brugada, Verckei and Moccetti et al 

Disease Assessment: 
Consensus criteria for ARVD/C and Short QT Syndrome
5-yr risk of SCD in HCM (O'Mahon et al, and AHA)and LQTS (1-2-3-LQTS-Risk)
5-yr risk of life threatening VTA with LMNA variant
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 and BLISTER CIED infection risk 

Misc:
Confirm conduction system capture with LBBAP.
myPace personalized heart rate calculator
A CIED/electrocautery manager is included. Detailed preoperative plans can be created and shared by text or email.
Clinical guidelines and consensus statement resource i
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)

## epTools Reviews in United States

### ***-- "Pvc"
Need better tools for PVC localization
-- yoelmd, 2020-09-24

### ***** "Great App"
Really helpful and handy for many EP issues.
-- Gnorschbladt, 2019-12-12

### *---- "This app is okay."
But not as great as I thought it would be.
-- allmoneyin23, 2019-12-08

### ***** "Love this app"
A colleague showed me this app while we were attending HRS in Denver. Started using it right away. Very useful for those of us who have trouble remembering any "rules".
-- Queenie19104, 2013-05-28

### ***** "Awesome!!!"
This is the best EP app I've ever seen!
-- Mmportner, 2013-01-19

### ***** "Great app!"
Thank you for this excellent app. Suggested addition: New algorithm using only lead aVR for differential diagnosis of wide QRS complex tachycardia. Heart Rhythm. 2008 Jan;5(1):89-98.
--
Addendum: remains excellent with update to 2.0. Thank you for adding the suggestion above!
-- MGKatz036, 2012-11-29

### ****- "Been waiting a while for this"
Cudos to the authors for finally developing an app for EP. There are countless of possibilities - aortic cusp , Rvot, entrainment criteria, long qt , AFib ablation techniques.
If this were updated with reasonable frequency, and expanded it wod be worth paying for/supporting !
-- Epsdog, 2011-06-19

### ***** "Awesome!!!"
great app, very useful, and easy to use. Highly recommended app.
-- Tnteia, 2011-05-23
