Question

In normal ECG ,PR and T wave are lies at ______________.

• A. Above the base line
• B. Below the base line
• C. partly above and partly below the base line
• D. Equal to the base line

Answer 1

The correct option is A Above the base line

An electrocardiogram or an ECG uses an instrument to record the electrical activities of the heart. It records the electrical impulses, more specifically the change in the electrical impulses of the heart, and plots it on a graph. The readings of an individual’s ECG are compared with a standard ECG to evaluate the working of the heart and checking it for any abnormalities or diseases. In a standard ECG, the P, R and T waves lie above the base.

So, the correct answer is 'Above the base line'.
