Question

"The electrocardiograph records both the intensity of and the actual time required for each part of the cardiac cycle."

a. True
b. False

Answer 1

The electrocardiograph does not record the intensity or time required for each part of the cardiac cycle.

Step-by-step explanation:

False. The statement is not true. The electrocardiograph, or ECG, records the electrical activity of the heart, not the intensity or time required for each part of the cardiac cycle. The ECG traces the depolarization and repolarization of the heart, which can help diagnose abnormalities in the heart's rhythm and function, but it does not directly measure the intensity or time of the cardiac cycle.
