Mobile web-based application (WPW24.com)
Each AP region, and all QRS types in all 12 leads, separately for the
full and baseline preexcitation patterns, were coded and introduced into
the application database to enable automatic cross-correlation between
AP localization and QRS morphology. A web-based application (WPW24.com),
optimized for mobile devices was developed. The WPW24.com is a client
side only progressive web app implemented with React and TypeScript. The
application enabled to graphically show changing distribution of APs
with regard to the introduced by the user, at each step, the QRS type in
a particular ECG lead. Providing the QRS type for the subsequent ECG
leads, pinpoints, in a stepwise manner, the area of maximum probability
of AP localization (Figures 4 - 6 and Supplementary
Video 1) . User can choose his/her own criteria/steps; there is
no need to adhere to any steps or order of assessment of ECG leads. Both
baseline and fully preexcited ECG can be used for map generation - per
user preference. Each question regarding morphology is provided with a
support – graphical illustration of several QRS types that are
compatible with that QRS morphology category.
