How to Choose the Right ECG Paper for Accurate Cardiac Readings

Choosing the right ECG paper is a small decision with a large impact. The right thermal chart paper ensures clear waveform visibility, reliable diagnostic readings, and trouble-free printing — all vital in busy cardiac units and diagnostic labs.
Why ECG Paper Matters
ECG machines reproduce electrical heart activity onto thermal chart paper. Poor quality paper can cause faint traces, smudging, or machine jams — risking misinterpretation and repeat tests. Using certified, high-quality ECG/TMT/CTG papers minimizes these problems and supports clinical accuracy.
Key Criteria When Selecting ECG Paper
1. Paper Type & Coating
Use thermal paper specifically designed for medical recorders (not generic thermal rolls).
Look for stable thermal coating to prevent fading.
2. Grid Format & Size
Choose the correct grid size (standard 1 mm boxes) and the paper width compatible with your ECG/TMT/CTG device.
Confirm length and perforation options for your workflow.
3. Print Clarity & Durability
High contrast grids and dark traces are essential. Check sample prints before bulk purchase.
Consider fade resistance for records that must be archived.
4. Compatibility & Certifications
Verify your paper is compatible with the make/model of your ECG machine.
Prefer ISO/CE-certified papers for consistent performance and regulatory compliance.
5. Storage & Handling
Store papers in a cool, dry place away from sunlight to preserve coating.
Keep rolls in original packing until use.
Practical Tips for Hospitals & Clinics
Maintain a small sample stock of different widths if you use multiple machine models.
Run routine machine-paper compatibility checks during preventive maintenance.
Label paper batches with purchase dates to rotate stock and avoid expired or degraded rolls.
