Each area has its own purpose and saved context.
Beta preview · cardiac rehearsal
Work through an authored adult arrest with CPR, AED prompts, and a timed handoff, or preview medication, defibrillator, CPR, and focused cardiac ultrasound setup in Skills. Tools vary by skill level. Virtual actions do not change the patient, ECG, heart model, or outcome.

Tabletop live leads selected. No live leads connected; hardware input is not implemented. ECG remains simulated.
Adult male, no placement cues
Drag an electrode, or select it and click the patient. With an electrode focused, use arrow keys to move it; Shift makes smaller moves.

Assessment workspace
EMT / BLS · Supplemental knowledge practice
Practice scene safety, patient assessment, AED workflow, transport, and handoff in five versioned questions. Scores are for learning only; there is no pass threshold or clinical competency award. Draft items need clinical and instructional review. The optional legacy BLS ECG bank covers rhythm and signal recognition only.
EMT / BLS · Beta rehearsal
Work through five timed cases covering scene safety, patient assessment, treatment and transport, and team operations. Reveal evidence, choose a response, and build a receiver handoff.
ECG Technician · Exam & Testing
Work through the 40 certification-path lesson checks. New answers save as versioned attempts; prior course completion and existing exam scores keep their original meaning.
Telemetry · Formative case
Build a source-supported monitor alert, work an acknowledged or unanswered response, and hand off a changed bedside report with clear next ownership.
Telemetry · Formative case
Follow a bed move with a stale central label and an uncertain signal. Verify the patient, transmitter, display, and alarm receiver links, then transfer the open event review.
Paramedic / ACLS · Formative case
Inspect patient and monitor evidence separately, choose a shockable or nonshockable branch, then reclassify an organized rhythm without assuming circulation has returned.
Critical care / 12-lead · Formative case
Compare bedside perfusion, pressure quality, and two authored 12-lead findings. Build a time-stamped report that keeps urgent concerns and unanswered questions visible.

Course intro
This course teaches patient safety, ECG acquisition, measurement, pattern recognition, and communication. BLS topics are included where relevant. It does not expand scope of practice, grant certification, or authorize diagnosis or treatment outside local protocol.
EKG Trainer is an educational simulator only. It is not a medical device and must not be used to diagnose, monitor, treat, or guide care for a real patient. In real care, use approved equipment, local protocols, medical direction, and current CPR/AED guidance.

Step 1 of 7
Quick start
This tour explains where to go first without showing placement answers.
Base training starts unassisted. Help layers stay optional.
Educational boundary
EKG Trainer is an educational simulator for lead placement practice, ECG pattern recognition, and visual cardiac-mechanism teaching. It is not intended to diagnose, monitor, treat, or guide care for a real patient.
Simulator cases, generated ECG and heart views, and lead effects are authored teaching models. Photorealistic course illustrations show training context, not findings from those cases. Separate recorded reference signals are credited where they appear.
Cases should be reviewed against multiple reputable sources and, before public release, by a qualified ECG educator, clinician, or medical director.
Help, anatomy, clinical overlays, and library tools are optional study aids. Base placement practice starts unassisted so learners can demonstrate competency.
Local-first privacy
EKG Trainer is an educational simulator that does not require an account or send learner progress to a cloud service. This build has no analytics or advertising trackers. It checks a OneDrive folder for updates at startup, and the optional Clinical Review workspace saves reviewer notes to a local OneDrive-synced file.
The app may save training preferences, module level settings, course progress, quiz answers, quiz history, and first-run tutorial status in local app storage so the learner can continue later.
Simulator cases and patient profiles are fictional. Course illustrations provide setting context, not case findings. The Reference ECG gallery uses credited, de-identified PTB-XL recordings; a Critical Care lesson includes a separate credited arterial-pressure excerpt from PhysioNet Challenge 2015. Documentary training photographs in course lessons depict separate training scenes and are labeled beside each image. Users should not enter real patient identifiers, protected health information, or live clinical data.
At startup, the installed app may contact a password-protected OneDrive update folder to check for a newer installer. Downloading the installer from a website may create normal website/server logs, which are covered by that website's separate privacy policy.
Learner progress and quiz history stay in local app storage. If Clinical Review is used, reviewer names, notes, and status are saved in a local JSON file that may sync through the owner's OneDrive.
Electron and Chromium may create normal local cache or application-support files required to run the desktop app. These files remain on the user's computer unless removed by the user or uninstaller.
This policy covers the installed EKG Trainer application. It does not cover external websites, download hosting providers, payment processors, or support channels.
Export a local backup, import one on another device, or clear training progress and the first-run tutorial flag.
CET lesson-check attempts use a separate local backup. Export both files to transfer all training records.
Software license
By installing or using EKG Trainer, the user agrees that the application is licensed for educational ECG training and simulation use only. It is not a medical device, patient monitor, diagnostic system, treatment tool, or replacement for qualified clinical instruction, local protocol, medical direction, or professional judgment.
The publisher grants the user a limited, revocable, non-exclusive, non-transferable license to install and use the application for personal, educational, classroom, or internal training purposes, subject to these terms.
The user may not reverse engineer, resell, sublicense, redistribute modified copies, remove notices, bypass access controls, or use the software to provide clinical diagnosis or patient care decisions. These software restrictions do not limit rights granted by separate third-party licenses for the included PTB-XL Reference ECG recordings or the unmodified CardioNetworks ECHOpedia echocardiogram clips. Recipients may exercise those files' respective Creative Commons rights independently of this software license.
Simulator cases, patient profiles, visual models, generated ECG waveforms, and feedback are learning content. The separate Reference ECG gallery and normal echocardiogram atlas display attributed recordings that are independent of the fictional cases. Users must verify clinical knowledge against approved curriculum, medical direction, and qualified instruction.
The user is responsible for following their own scope of practice, employer policy, local protocol, certification requirements, and applicable law. The app does not authorize any clinical skill or expand clinical scope.
The application, visual assets, code, simulations, course materials, and training content remain the property of the publisher or applicable rights holder. The PTB-XL reference recordings retain their source attribution and Creative Commons Attribution 4.0 rights. The unmodified CardioNetworks ECHOpedia echocardiogram clips retain their source attribution and Creative Commons Attribution-ShareAlike 3.0 rights, including the right to share and adapt the clips under that license. The software is licensed, not sold.
Updates may add, change, or remove features, content, cases, layouts, and training tools. Continued use after an update means the user accepts the updated application behavior and terms included with that version.
Local saved progress, quiz history, and preferences are addressed in the Privacy Policy. Users should not enter real patient identifiers, protected health information, or live clinical data into the simulator.
The software is provided as-is for training use. To the maximum extent permitted by law, the publisher disclaims implied warranties, including merchantability, fitness for a particular purpose, and non-infringement.
To the maximum extent permitted by law, the publisher is not liable for indirect, incidental, consequential, special, exemplary, or clinical-care-related damages arising from use or inability to use the software.
The software license may terminate if the user violates these terms. Upon termination, the user must stop using the software and uninstall or delete application copies under their control. Termination does not remove rights granted directly by the separate licenses for included third-party recordings.
Schools, agencies, departments, and training programs are responsible for validating course fit, documenting approvals, supervising learners, and determining whether the software satisfies any local education requirement.
This template should be reviewed and finalized by qualified legal counsel before public distribution, paid licensing, institutional sale, app-store release, or continuing-education deployment.
