For instructors
Run the simulation from your phone
A tablet with the simulator beside the manikin, and the controls on the instructor's phone — rhythm, drugs, deterioration, shock. The team sees only what they would see for real.
-
Session with a code
A 4-digit code. Everyone joins on their own screen, with no install and no account.
-
Real-time control
Change the rhythm and it shows on the monitor instantly.
-
Drugs and interventions
Epinephrine, adenosine, amiodarone, defibrillation, CPR.
-
Artifacts and noise
Interference, movement, a loose electrode. Reality is rarely clean.
Creation
Your rhythms. Your scenarios.
19 rhythms come ready. Whatever is missing, you build.
Create your clinical scenarios
Chain the case. Reuse it in every session.
Academy
Learn to interpret ECGs, in short lessons
Short lessons on cardiac rhythm interpretation, each with its own quiz. Widely used as study support for official courses such as ALS.
It does not replace any official course or certification. It is training and preparation.
Features
Clinical realism, built for teaching
-
Realistic ECG engine
19 cardiac rhythms with faithful morphology: AF, flutter, SVT, VT, torsades, VF, asystole, PEA, AV blocks, paced.
-
Hemodynamic parameters
HR, blood pressure, SpO₂, EtCO₂, RR and temperature, with rhythm-specific profiles.
-
Real-time sync
The instructor sets it, the trainees see it. In the browser, nothing to install.
-
Drugs and interventions
Epinephrine, adenosine, amiodarone, defibrillation, cardioversion, CPR.
-
Scenarios and quizzes
Guided cases and recognition questions — or build your own.
-
Built for the emergency
Built around emergency care and hemodynamic instability.

Why it exists
Born from the reality of critical care
In the emergency room there is an instant when everything converges on the monitor. A trace appears and the team waits for the reading from whoever knows. There is no time to look it up, and no room to hesitate.
The rhythms that decide the most are, precisely, the ones you see the least. A torsades, a fine ventricular fibrillation, a complete block — months can pass without them showing up. And when they do, they give no warning. Nobody prepares for what they almost never meet.
My ECG Academy was born from a group of healthcare professionals working in critical care, who knew this gap from the inside. The intent is simple: a place where those rhythms can be seen as many times as needed, where decisions are trained without consequences, and from which you reach the real moment with your eye already trained.
