Explanation:
Detailed explanation-1: -Explanation: The output or height of the ECG waveform is controlled by the gain control. If you change this setting, you must record the change on the ECG report.
Detailed explanation-2: -The PR segment serves as the baseline (also referred to as reference line or isoelectric line) of the ECG curve. The amplitude of any deflection/wave is measured by using the PR segment as the baseline. Figure 4. Impulse transmission from the atria to the ventricles.
Detailed explanation-3: -Vertically, the ECG graph measures the height (amplitude) of a given wave or deflection. The standard calibration is 10 mm (10 small boxes), equal to 1 mV.
