The ECG course is part of PRO: 39 000 UZS a month. Verify your account (e-mail or Telegram) and PRO opens free for 3 days, so you can try the whole course.

What does the certificate mean?

Passing the Level A exam earns the "ECG fundamentals" certificate, which anyone can verify by its code. It is a MedIQ learning certificate, not credits or an official qualification.

Does it work on a phone?

Yes, the course runs in the browser and is made for phones too. The calipers and the 3D lab are easier on a larger screen, but they work on a phone.

Lessons, interpretations and questions are in Uzbek, Russian and English. You can switch at any time.

Inside the course

Seven tools, one goal: reading the ECG yourself

12-lead ECG

Read a real ECG as if on paper

Every lesson shows the ECG on millimetre grid paper with calibration and paper speed. Zoom into a lead, measure with calipers and compare your conclusion with the interpretation.

A systematic read: rhythm, rate, intervals, axis, waves
The Full read drill grades your report
Questions inside the lesson with instant feedback

ECG library

Real recordings diagnosed by physicians

The library's ECGs come from open clinical datasets, sorted by topic. The diagnosis is the dataset physicians' label; MedIQ AI never changes it.

A conclusion, measurements and an interpretation for each

ECG tools

Measure and calculate

Measure intervals and amplitudes on a real ECG with calipers. The rate, QTc, voltage and axis calculators compare your result with normal values.

Bedside monitor

See and hear the rhythm

The monitor shows lead II, the SpO₂ pleth wave and a beep for every QRS. See how the alarms behave on model rhythms.

3D lab

Where the ECG waves come from

Watch in 3D how the wave of excitation travels from the sinus node to the Purkinje fibres, and which part of the ECG each step makes.

Normal rhythm, blocks, WPW, atrial flutter
The wave and the ECG trace side by side
Step-by-step playback and pause

ECG machine trainer

Learn to record an ECG correctly

On a generic 3D electrocardiograph, learn the parts, set paper speed, gain and filters, and find and fix recording faults.

Settings: speed, gain, filters
Troubleshooting and a quiz

Practice and certificate

A little every day, with a certificate at the end

The daily ECG keeps your eye in, while Rhythm sprint and Full read build speed and accuracy. Pass the Level A exam to earn the "ECG fundamentals" certificate.

The daily ECG and your streak
Rhythm sprint and Full read drills
Level A exam: 30 questions, 45 minutes

Quality and sources

Real data, open sources, honest labels

Open clinical datasets
The real ECGs come from open datasets that allow commercial use; the source and licence are shown under every recording.
Diagnoses from physicians
A real ECG's diagnosis is the dataset physicians' label. MedIQ AI never re-diagnoses it.
The "Model" label
Synthetic recordings from the rhythm generator and the simulators are always labelled "Model": they are not a patient's ECG.
Beta and the report button
MedIQ AI checked the content twice, independently; a physician has not reviewed it yet. Every page has a button to report an error.
