Thermal recording paper
Also called: Thermal ECG paper, thermosensitive paper
Thermal recording paper — Paper coated with a heat-sensitive layer that darkens where the recorder’s thermal print head heats it — the standard medium for ECG and CTG records.
The coating reacts to heat, so the same chemistry that makes the trace also makes it vulnerable: heat, sunlight, humidity, plasticisers in PVC sleeves, solvents and alcohol hand rub can fade or darken the record over time.
Paper must match the recorder’s width, fold, grid and sensing marks, and should be stored cool and dry in its sealed pack until use.
