Developed for anyone who is interested in mastering the complexity of the electrical function of the heart. This app helps healthcare professionals and medical/nursing students gain deeper understanding of the ECG. It employs interactive real-time 3D exploration to aid learning of the cardiac rhythm. All text is available in English, German, Spanish, Mandarin 所有文字均以中文提供 and Greek. Tutorial voice over text is available in English. Use Apple Pencil or a soft rubber tip pen for better interaction. ECG is one of the most common diagnostics for Cardiology that all medical and nursing students are introduced at an early stage of their training. Confidence and experience gained from simulated training can help make first diagnosis successful and decrease risk to patients. This app uses real-time 3D anatomy and control of physiological parameters. Utilises electrophysiology simulation and live ECG signals to simulate the normal heart rhythm. APP FEATURES Introductory tutorial with voice-over Electrophysiology parameters: SA node switch on/off SA node rate 30-150bpm AV node block/unblock Escape Rhythm Live single lead ECG display Live 12-lead ECG display Annotated 12-lead ECG display Pause and scroll ECG with simultaneous action potential wavefront and 3d heart vector view ECG calliper tool Simulation speed control: Slow-Mo, Hi-Fi, Fast ECG speed control ECG voltage control ECG leads display with heart vector DCCV Cardioverter/Defibrillator Temporary pacing device with limited functions: On/off switch Pace indicator Interactive placement of pacing wire tip All other pacing parameters are disabled in this app. For fully functional pacemaker please see the Epicardio Temporary Cardiac Pacing app on AppStore. Anatomy views with free 3D camera control Choice of displayed anatomy Preset views General app settings: Sounds on/off Background colour options and brightness Screenshot info Tool tips on/off Languages: English, German, Spanish, Mandarin, Greek This app executes in landscape mode only TRAINING OBJECTIVES Understand what causes the ECG signals during normal sinus rhythm Explore the heart in 3D and gain spatial and temporal understanding of the heart's electrophysiology in normal sinus rhythm BENEFITS Mobility. Users can access individualised simulation training on their personal devices anytime and anywhere Guidance. Guided tutorials aid self-learning without the need for tutoring Model pacing outcomes. Normal vs. pathology overlays make it easy to visually compare differences in pacing that would otherwise need to be imagined Deeper understanding. Real-time interactive 3D anatomy and pacing wire placement provide spatial and temporal understanding of what causes the ECG signals and helps with retention Realistic simulation.
