The diagnostic test that records the electrical activity of the heart is called ECG or Electrocardiogram. An ECG is a painless and simple test, which uses electrodes arranged and attached to your skin, and records the activity of the heart. ECG detects any abnormal rhythm and pattern of the heart beat and this helps doctors in diagnosing arrhythmias.

There are choices for this question namely:
<span>a. 40% to 50%
b. 50% to 70%
c. 70% to 85%
d. 85% to 100%
The correct answer is 50% to 70%. Moderate-intensity activity is noted when a person reaches 50% to 70% of his or her maximum heart rate in exercise. The maximum heart rate is determined by subtracting the age to 220.
<em>For example, a 54-year-old male with type 2 diabetes needs to have moderate intensity activity. His maximum heart rate is (220-54) which is 166 bpm. 50% to 70% of 166 is 83-116 bpm. Therefore he should exercise and raise his heart rate at 83-116 bpm. </em>
