## Description

Generate ECG waveforms, annotate by hand on ECG paper canvas, and export high-res PNGs for slides and web. The waveform design tool built for medical educators.

ECGCanvas is a waveform design tool for medical educators — combining parametric ECG generation with freehand pen drawing on a single ECG paper canvas.

Made for
· Lecture slides (PowerPoint / Keynote )
· Web-based teaching materials and HTML pages
· Side-by-side arrhythmia and ST-change comparison figures
· Annotating waveforms that parametric generation can't capture alone

Parametric Waveform Engine
Start from 8 clinical presets and fine-tune every parameter with sliders. Normal sinus rhythm, STEMI, ST depression, de Winter, bradycardia, tachycardia, T-wave inversion — all ready in seconds.

【Clinical Presets】
Normal / Horizontal ST Depression / Downsloping ST Depression / de Winter / STEMI / Bradycardia / Tachycardia / T Inversion

【Adjustable Parameters】
Heart rate · Beat count · P wave (amplitude, duration, PR interval) · QRS (R amplitude, width) · ST morphology (flat / downsloping / upsloping / convex) · J point · T wave (amplitude, duration, inversion)

ECG Paper Canvas
A true ECG grid with 1mm and 5mm spacing. Place waveform blocks anywhere on the canvas — a single strip or a multi-waveform comparison layout.

Pen Annotation
Draw directly on the canvas to capture waveform morphologies that parameters alone can't produce. The pen auto-matches the ECG stroke width (2pt) for a consistent look.

Eraser
The eraser works on both pen strokes and waveform blocks. Erased waveforms are fixed visually but lose their editable parameters.

High-Quality PNG Export
Exports at 3× scale for crisp, print-ready images — no blurring on Retina screens. Saved directly to Photos, ready to drop into slides or web pages.

Fast and Focused
No clutter, no recording, no unnecessary features. Open the app, build your figure, export. That's it.

Save time on lecture prep with ECGCanvas.
