Plotting the ECG in volts against seconds

The data in the ECG file contains the voltages measured by the A/D converter. However, we have not taken into account the gain of the pre-amplifier which has been g=500. Therefore we divide the data by 500 to get a proper plot in V. The time is already in sec so that there is no need to convert it.

Now we have the seen the ECG in the time-domain. Let's have a look at its frequency-spectrum.
