- 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.

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:
In this FREE PDF (and accompanying video), you'll discover: What the cardiac cycle is. How the ECG triggers everything else. What happens to ventricular volume. Atrial and ventricular pressure during the cycle. Heart sounds during the cycle.
“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
The cardiac cycle refers to the pattern of contraction and relaxation of the heart during one complete heartbeat. Contraction of the heart muscle is known as systole and...
Introduction. Humans and many other animals depend on blood flowing through their bodies to keep them alive. The blood travels through a system that includes the heart and a network of blood vessels. This is called a cardiovascular system.
