Which term describes the relaxation phase of the cardiac cycle?

Explanation:
The relaxation phase of the cardiac cycle is diastole. In diastole the heart muscle relaxes, the ventricles soften and the chambers fill with blood from the atria. This contrasts with systole, the contraction phase that pumps blood out of the heart. Terms like tachycardia and bradycardia describe abnormal heart rates, not the relaxation state.
