This is done by you but The pictures in ecg are not right and is not good specially look into qrs complex it is way more outer than the ecg frame, take some realistic ecg pictures and redo it

ECG Practice Cases
PDF Document · PDF
The PDF is ready. Key improvements made to the ECG strips:
- All waveforms now stay within the grid frame - QRS complexes, P waves, and T waves are fully contained inside the ECG box
- Absolute coordinate system - each pattern is defined in fixed point offsets from the baseline (max +26pt up, -20pt down) instead of the old scaled units that were overflowing
- Clipping path added as a safety net so nothing can ever escape the grid boundary
- Realistic proportions - QRS R-wave peaks at ~22pt, S-wave dips to ~-14pt, P-waves at ~4pt, T-waves at ~7-8pt, matching standard ECG appearance
- Pattern-specific accuracy - VT has wide bizarre morphology, AFib has chaotic baseline with no P waves, STEMI shows elevated ST segments, Torsades twists around the baseline, paced rhythm shows pacing spikes, etc.
The ecg pictures are totally wrong, pick the pictures for a case from realistic picture and design it real, do it correct

Here is what changed compared to the previous version:
How the ECGs are now generated:
- Each ECG strip is synthesized using a Gaussian-sum cardiac model - the standard mathematical method used in ECG simulators. P wave, QRS complex, and T wave are each modelled as Gaussian curves with physiologically accurate timing, amplitude, and width.
- Rendered at 150 DPI on genuine ECG paper (pink background, red minor/major grid at 0.04s/0.1mV and 0.2s/0.5mV) with a 1mV calibration pulse.
Case-specific accuracy:
| Case | Pattern | Key visual feature |
|---|---|---|
| 1 | Normal sinus | Regular PQRST, 72 bpm |
| 2 | Atrial fibrillation | Chaotic f-wave baseline, irregular QRS, no P waves |
| 3 | Inferior STEMI | Elevated ST segment, hyperacute T, Q waves |
| 4 | SVT | Rapid narrow QRS at 210 bpm, retrograde P |
| 5 | CHB escape | Slow 38 bpm wide escape beats |
| 6 | VT | Wide bizarre QRS at 180 bpm |
| 7 | LBBB | Broad notched R, discordant T |
| 8 | WPW | Short PR, visible delta wave slurring |
| 9 | Mobitz II | P waves present but some not conducted |
| 10 | Hyperkalaemia | Tall peaked narrow T waves, wide QRS |
| 11 | Hypokalaemia | Flat T, prominent U wave, ST depression |
| 12 | PVC | One premature wide beat against sinus background |
| 14 | Torsades | Twisting polymorphic QRS amplitude |
| 15 | Paced | Visible pacing spikes before P and QRS |
| 19 | VF | Completely chaotic, no identifiable QRS |
| 20 | Long QT | Prolonged QT with late broad T wave |
That's good
Glad it worked out! The ECG strips now show genuine waveform morphology for each condition - you can actually see the difference between a normal sinus beat, the chaotic f-waves of AF, the wide notched R of LBBB, the twisting amplitude of Torsades, etc.
If you want any refinements - adjusting heart rates, waveform amplitudes, adding more leads, or tweaking any specific case - just let me know.
