ECG PAPER A4 SIZE (150 SHEET)

Engineered for advanced multi-channel and 12-lead diagnostic electrocardiography systems, this full-format A4 Z-fold thermal paper provides comprehensive, full-page cardiac recording. The generous A4 surface allows simultaneous visualization of all 12 standard leads alongside extended rhythm strips, patient demographic data, and calculated interval metrics on a single, unified sheet. Manufactured from medical-grade thermal base stock, it features high-precision millimeter background grids printed in low-interference, calibrated red or orange ink. Its heat-sensitive chemical layer triggers rapidly at low thermal-head energy levels, producing deep black, smudge-free waveforms that clearly highlight subtle diagnostic markers like ST-segment shifts, small Q-waves, and complex arrhythmias. The continuous Z-fold design with clean micro-perforations guarantees smooth, flat feeding without curl or paper jams, while allowing effortless tearing and direct filing into standard medical charts and binders. With archival-grade resistance against ambient heat, light, and clinical moisture, this 150-sheet pack is an indispensable consumable for hospital cardiology departments, diagnostic laboratories, and intensive care units.
