In EKG standardization, what does 1 mV of amplitude equate to?

In EKG standardization, 1 mV of amplitude is conventionally set to equal 10 mm in height on the ECG tracing. This standardization is crucial for accurate interpretation of the electrical activity of the heart, as it allows for consistent measurements irrespective of the calibration settings of different machines. By adhering to this standard, healthcare providers can accurately assess amplitudes of various waveform components, such as P waves, QRS complexes, and T waves, ensuring that the interpretation reflects true physiological conditions. This standardization aids in diagnosing conditions like hypertrophy and ischemia, where precise amplitude measurements can reveal significant underlying issues.
