Feb 12, 2017 · 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.

Aug 23, 2023 · The cardiac cycle is the series of events that take place in one heart beat, including muscle contraction and relaxation. The contraction of the heart is called systole, while the relaxation of the heart is called diastole. One cardiac cycle is followed by another in a continuous process. There is no gap between cycles where blood stops flowing.
“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.
