epTools is a platform for the evaluation of heart rhythm disorders. It is a universal app running on iPad, iPhone and iPod Touch devices.
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. Algorithms are implemented via an intuitive user interface. These algorithms guide the user 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.
Users may access scientific reference material cited in the app. Many of the references are available for free or are easily accessible by subscription holders.
Localization of accessory pathways: 3 algorithms are provided (based on Arruda, Milstein and Taguchi et al) to assist in the localization of accessory pathways in patients presenting with patterns of manifest pre-excitation on 12-lead electrocardiograms.
Localization of atrial tachycardias: Two algorithms are provided (based on Ellenbogen et al and Kistler et al) to assist in the localization of atrial tachycardias in patients presenting with atrial tachycardia on a 12-lead electrocardiogram. An additional tool based on De Ponti et al is provided to calculate the appropriate mapping window to identify the isthmus of an atrial tachycardia.
Localization of ischemic ventricular tachycardia: Two algorithms are provided (based on Miller et al and Segal 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.
Localization of idiopathic ventricular tachycardia and premature ventricular contractions: A reference is provided consisting of ECG findings for various idiopathic ventricular arrhythmia locations. Two algorithms are provided (based on Ito et al and Park et al) to assist in the localization of ventricular ectopic activity and tachycardia. Six tools are provided to differentiate right ventricular 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 and R-Wave Duration indices.
2 tools to differentiate endocardial from epicardial ventricular arrhythmias are provided. These include calculation of the maximum deflection index (Daniels et al) and the Berruezo criteria.
Disease Assessment: Consensus criteria forArrythmogenic Right Ventricular Dysplasia/Cardiomyopathy (ARVD/C) and Short QT Syndrome. Calculators for estimated 5-yr risk of SCD in HCM (O'Mahon et al), the likelihood of inadequate defibrillation safety margin (Hsu et al ), extent of left atrial arrhythmogenic substrate (Kosiuk et al), 30-day all-cause mortality after PPM and ICD lead extraction (Brunner et al) and 1-4 year mortality rate for patients undergoing primary prevention ICD placement (Bilchick et al, SHOCKED) are provided.
A clinical guidelines and consensus statement resource is provided.
Access to the CredibleMeds® (powered by AZCERT.org) database of drugs which may prolong the QT interval is provided.
Tools to differentiate SVT from VT using 12-lead electrocardiogram features utilizing the Brugada and Verckei et al algorithms.
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 et al) and a CL to bpm interconverter are provided.
Reference examples using the included tools are available on our website (www.busy-being-born.com/examples).
