WebApr 20, 2024 · 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. On occasion, particularly when the waveforms are small, double standard is used (20 mm equals 1 mv). When the wave forms are very large, half standard may be used (5 mm equals 1 mv). WebWhen you are looking at a telemetry strip or EKG, you are seeing electrical impulses generated by your heart that are being transferred to electrodes (the sticky patches on your patient’s skin), which in turn displays that impulse on a screen for you to analyze.
