What should be done before and after using an EKG?

Standardizing the EKG is a crucial step before and after using the machine because it ensures that the EKG readings are reliable and consistent. This process involves adjusting the machine so that the standardization mark (typically 10 mm high) appears as expected on the graph, allowing for accurate assessment of the heart's electrical activity. By standardizing, it sets a baseline that can be trusted when interpreting results, making it particularly important for identifying any deviations that may suggest pathology.

Establishing this standardized reference helps in ensuring that comparisons can be appropriately made against accepted norms and that any diagnosed conditions can be monitored over time for changes. Without proper standardization, variations that could arise from machine discrepancies might lead to misinterpretation of results, impacting patient care.
