What are the common sizes of ECG paper

An electrocardiograph is a common medical device that records changes in the electrical activity of the heart. The ECG machine needs to use special paper to record accurate ECG results. This article will describe the sizes of paper commonly used in ECG machines.

There are three main sizes of paper commonly used in ECG machines: 210 mm × 297 mm, 110 mm × 140 mm, and 63.5 mm × 30 m.

The first is the size of 210 mm × 297 mm, which is the standard size of A4 paper, also known as full-sheet paper. This size paper is suitable for most EKG machines and can record a 12-lead ECG, where each row can accommodate 6 leads, and there are two rows in total. This kind of paper is relatively large and can record complete ECG data, but it needs to be cropped when used for easy viewing and storage by patients.

This is followed by a size of 110 mm x 140 mm, also known as a small sheet. This size paper is suitable for hand-held ECG machines, which can record 1-3 lead ECG. Due to its small size, it is easy to carry and store, but only part of the ECG data can be recorded.

Finally there is the 63.5 mm x 30 m size, also known as roll-fed. This size paper is suitable for continuous recording of ECG, which can record ECG data for 24 hours or more. Due to its long length, large amounts of ECG data can be stored without frequent paper changes.

In general, the choice of paper for an ECG machine needs to be made on a case-by-case basis, mainly depending on the type of equipment used and the amount of ECG data that needs to be recorded. Understanding the characteristics of different sizes of paper can help medical staff better choose the appropriate paper for ECG machines, and improve the accuracy and efficiency of ECG recording.
