Study Notes

ECG Recordings: Time Intervals

One small square on the vertical axis represents a duration of 0.1 mV (millivolts).
One large square on the horizontal axis corresponds to a duration of 0.2 seconds.
Each large square on the horizontal axis consists of 5 small squares.
Therefore, five large squares on the horizontal axis total a duration of 1 second.
The vertical axis in ECG recordings shows voltage, while the horizontal axis indicates time.
