The four phases of the cardiac cycle are diastole, isovolumetric contraction, systole, and isovolumetric relaxation. During diastole, the heart muscles relax and the chambers fill with blood. In isovolumetric contraction, the heart muscles contract but the chambers do not change volume. Systole is when the chambers contract and blood is ejected. Finally, isovolumetric relaxation is when the heart relaxes but the chambers do not change volume.

What are phases of the cardiac cycle that shortens most in response to tachycardia?
The diastolic phase of the cardiac cycle shortens the most in response to tachycardia. This includes the time spent in ventricular filling (diastasis) and atrial contraction (atrial systole), as these phases are compressed to accommodate the faster heart rate.
What are the four phrases of the lunar cycle?
The four main phases of the lunar cycle are the New Moon (which is not visible except during an eclipse), First Quarter (waxing half moon), Full Moon (all of which is visible) and Third Quarter (waning half moon). The moon phases in between the four main phases are the crescent and gibbous phases.
How long does it take to complete one cardiac cycle?
A cardiac cycle typically lasts about 0.8 seconds in a resting adult, but this duration can vary based on heart rate and individual health. The cycle consists of two main phases: diastole, when the heart relaxes and fills with blood, and systole, when the heart contracts to pump blood out. During exercise or increased physical activity, the cardiac cycle may shorten as the heart rate increases.
What are four phases of the infornmation processing cycle?

What is the period of time called between the beginning of one heartbeat and the start of the next?
The period of time between the beginning of one heartbeat and the start of the next is known as the cardiac cycle. It consists of two phases: systole (contraction of the heart muscles) and diastole (relaxation of the heart muscles).
