ECG paper is used to record the electrical activity of the heart. It comes in various sizes and widths, with a grid pattern and thicker lines to enclose blocks. Using the wrong type of paper can result in inaccurate measurements. It’s important to read instructions and review return policies.
Electrocardiography is the measurement of the electrical activity from the heart on a specialized piece of graph paper. Data is typically recorded on this document as part of an electrocardiogram (ECG), in which electrodes are attached to a person’s chest and the heart’s electrical impulses are measured. Typically a certain type of paper is required to give accurate results. The type of ECG paper used may depend on the model and make of the machine; sometimes it comes in rolls, but folded paper is often needed. There are also various sizes and widths of paper, some of which are designed to run at certain speeds.
A grid pattern is typical of ECG paper, and a series of lines criss-cross to divide spaces into squares usually 0.04 inch (one millimeter) wide. Darker lines, usually red, cross to block squares five squares wide and five squares high. Most types of EKG paper also have even thicker lines to enclose blocks of four, five by five squares. The heart activity monitor usually draws a line in black ink to represent electrical signals. Boxes touched by tracer ink lines can be analyzed with measurements common to almost all countries.
The configuration of most types of ECG paper includes a measurement of time and voltage of electrical activity. Many types of it come in sheets, often designed in a Z-fold pattern. How this paper is stored may be different than how strips that arrive in rolls are stored before use. Roll paper is sold by many manufacturers. Both types of ECG paper can be of various widths and lengths, while the product can vary in terms of packaging; the amount of sheets can also vary drastically.
EKGs are a common form of noninvasive recording of heart activity. There are many manufacturers who can offer different brands of ECG paper. Each type is often different based on the particular machine, so it’s usually important to read the instructions to know what type of paper to order. Rolls typically vary in circumference, so usually the right size will be the only one to fit your machine’s feeder.
If the wrong type of ECG paper is used, tracer line measurements may be inaccurate. The size and type can also be important so that the mechanism of the machine does not interfere with the results. It’s often helpful to review manufacturers’ and suppliers’ return policies in case an error is made in an order, so that the wrong type of paper can be replaced with the right product.
