ECG paper is special paper used to record electrocardiograms, which play an important role in the medical field. This article will explore the historical evolution of ECG paper and technological advances in recent years.

The historical evolution of ECG paper can be traced back to the end of the 19th century, when Dutch doctor Willem Avenheim invented the first ECG machine and used wax paper to record ECG signals.

Subsequently, in order to better record and interpret the ECG, people began to study and improve the ECG chart.

The original ECG paper used traditional wax paper, but there were problems such as unstable records and difficult preservation. In the early 20th century, Irish cardiologist Gene Holness introduced relatively stable paraffin paper, which made the recording of electrocardiograms more reliable. This paper has a smooth surface that prevents the paper from being distorted by perspiration or moisture.

With the advancement of science and technology, the technology of ECG drawing has also been innovated and developed. In recent years, the emergence of digital ECG has gradually digitized ECG paper. Digital ECG no longer requires traditional paper records, but uses electronic equipment to directly convert ECG signals into digital data and store them in computers or the cloud. This digital record not only improves the accuracy and stability of the record, but also facilitates the review and analysis of doctors.

In recent years, some new ECG paper have also been developed. For example, flexible ECG paper are made of highly elastic materials, which can fit the skin and stretch freely following the patient's movement, providing more accurate and reliable ECG signals. In addition, some ECG paper also incorporate biosensor technology to monitor other important physiological parameters besides ECG signals, such as respiration and body temperature, providing doctors with more comprehensive clinical data.

With the rapid development of artificial intelligence technology, new breakthroughs have also been made in the field of ECG paper. Through deep learning algorithms, people can analyze and train a large amount of ECG data, and then develop an automatic diagnosis system to help doctors judge heart diseases more quickly and improve diagnosis efficiency.

As an indispensable tool in the medical field, ECG paper have experienced the development process from wax paper to paraffin paper, and then to digital paper. In recent years, digitalization, flexibility and intelligence are important development directions of ECG drawing technology. The innovation and application of these technologies will further improve the accuracy, stability and clinical application value of ECG.
