What is the standardization amplitude for EKG readings?

The standardization amplitude for EKG readings is set at a height of 10 mm, which corresponds to a standardized deflection on the EKG paper. This is a critical factor in ensuring that the EKG readings are consistent and comparable across different tests, as the height of the waves on the EKG indicates the electrical activity of the heart. A standardization of 10 mm high allows for clear visualization of the heart's electrical signals, facilitating accurate interpretation and diagnosis by healthcare professionals.

The width is generally not emphasized to the same extent as the amplitude, but it is typically set to 5 mm per second, which corresponds to the speed of the paper moving. This means that when the markers on the EKG strip reflect these standard heights and widths, healthcare providers can effectively assess heart rhythms, heart rate, and other cardiac conditions. The choice indicating 10 mm high and 5 mm wide aligns perfectly with established EKG practices.
