Explanation / Answer

1. Electrocardiogram (ECG) is used to record the electric activity of heart. The standard paper speed set to record the ECG is 25mm/sec. it would be difficult to read ECG whenn the paper speed is 50mm/sec. Option B is correct.

2. If one second is equal to 25mm, then one mm is equal to 0.04 sec (1/25 = 0.04). Option B is correct.

3. On EKG paper, a large box represents 25 small boxes which correspond to 25mm space of large box and is recoreded in one second. Thus each small box is 1mm in size. The option D is correct.

4. Once the electrodes are placed then, the machine should be calibrated as it can run on an ideal speed and with constant electrical activity. Thus, option C is correct.
