Thermal Paper 50mmX20m ECG Chart Recorder

ECG Paper is a special paper used to record electrocardiogram (ECG) signals. It is usually white or light yellow with a certain thickness and smoothness to ensure clear and accurate signals. ECG Paper is usually printed with a series of horizontal and vertical lines to help a doctor or technician analyze and interpret the ECG signal. The lines typically represent time and voltage so that aspects of the ECG waveform, such as heart rate, rhythm, cardiac rhythm, and cardiac function, can be measured.
