Answer 2

For an accurate measurement of cardiovascular activity, researchers typically: D) measure the number of heartbeats per minute.

What is cardiac cycle?

Cardiac cycle is a process that involves the complete heartbeat of the human heart, which comprises sequential alternating contraction and relaxation of the atria and ventricles, so as to cause blood to only flow in one direction throughout the human body during any cardiovascular activity.

As a general, researchers should typically measure the number of heartbeats of a person per minute, so as to ensure an accurate measurement of cardiovascular activity.
