What is one complete heartbeat combining the contraction and relaxation phases known as?

Cardiac arrest
Heart rhythm
Cardiac cycle
Pulse

The correct answer is: Cardiac cycle

Option A, Cardiac arrest, is incorrect because it refers to a condition where the heartbeat stops completely, while the question is asking for the complete heartbeat cycle. Option B, Heart rhythm, is incorrect because it refers to the pattern of heartbeats, not the complete cycle. Option D, Pulse, is incorrect because it refers to the rhythmic expansion and contraction of arteries due to the heartbeat, not the complete cycle of contraction and relaxation phases.
