The RITMIA™ Smartphone App for Automated Detection of Atrial Fibrillation: Accuracy in Consecutive Patients Undergoing Elective Electrical Cardioversion

Figure 2

Examples of 12-lead ECG (left side) with the cloud-based interface of the RITMIA™ App showing the paired recording (right side). RR intervals are plotted on a graph showing RR interval on the y-axis and time on the x-axis. A colour-code is automatically attributed to each dot, corresponding to the automated diagnosis as “probable AF”=red, “unclassified non-AF arrhythmia”=yellow and “normal rhythm”=blue. (a) pre-ECV 12-lead ECG showing atrial fibrillation and paired App recording automatically labelled as “probable AF”. (b) post-ECV 12-lead ECG showing restoration of sinus rhythm and paired App recording automatically labelled as “normal rhythm” and “unclassified non-AF arrhythmia”. ECV: electrical cardioversion. AF: atrial fibrillation.
