Electrocardiography (ECG)

Electrocardiography is a non-invasive procedure for recording electrical changes in the heart. ECG paper is traditionally divided into 1 mm squares. Vertically, ten blocks usually correspond to 1 mV, and on the horizontal axis, the paper speed is usually 25 mm/s, so one block is 0.04s (or 40ms). Through the simulated virtual activity, user can identify whether the heart rhythm is regular or irregular from the ECG waveform produced.

     Click and drag the wires from the ECG machine to the leads in the body in such a way that all the leads are correctly connected to the machine. (Colours of the leads should match with the dots.)

     After the successful connection, a button 'Take ECG' will be enabled.

     The ECG will plot for all the leads separately.

     Click 'Zoom in'  and 'zoom out' button for changing the view and reset button to reset the connection.
