Question

Find the odd one. Write down the common features of others.

Bypass surgery, ECG, EEG, Pacemaker.

Answer 1

The odd one out is EEG (Electroencephalogram). It is used to detect the problems associated with the electrical activities of the brain.

The other three are associated with heart diseases.

Bypass surgery is done to restore normal blood flow to an obstructed coronary artery.

EEG is for recording the electrical activity of the heart to identify its abnormal functioning.

A pacemaker is a device placed in the heart for maintaining its normal rythm.
