- The cardiac cycle is the series of contractions in the heart that pressurize different chambers, causing blood to flood in one direction. There are two stages during the cardiac cycle. During diastole, the ventricles relax and fill with blood. The muscles contract during systole, pushing blood through the arteries.

6 days ago · The meaning of CARDIAC CYCLE is the complete sequence of events in the heart from the beginning of one beat to the beginning of the following beat : a complete heartbeat including systole and diastole.
“Cardiac cycle refers to the sequence of events that take place when the heart beats.” What is Cardiac Cycle? The cardiac cycle attributes to a comprehensive heartbeat from its production to the commencement of the next beat. It comprises diastole, the systole, and the intervening pause.
- The different phases of the cardiac cycle involve: Atrial diastole Atrial systole Isovolumic contraction Ventricular ejection Isovolumic relaxation...
- Systole is the period when the heart chambers contract that causes the ejection of blood into the aorta and pulmonary trunk.
- Diastole is the part of the cardiac cycle during which the heart refills blood after it is emptied during the systolic phase.
- The major symptoms of diastolic dysfunction include: Shortness of breath Weakness Dizziness Nausea Lack of appetite Coughing or wheezing
Define cardiac cycle, systole, and diastole. Describe the phases of the cardiac cycle including ventricular filling, isovolumic contraction, ventricular ejection, and isovolumic relaxation. Explain how atrial systole is related to ventricular filling.

The cardiac cycle refers to the sequence of events that occur when the heart beats. It is the complete cycle of filling and emptying the heart of blood because of heart muscle contraction. The cardiac cycle consists of two main phases: Diastole Phase: During this phase, the heart ventricles are relaxed and the heart fills with blood.
