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.
Oct 30, 2023 · The cardiac cycle is defined as a sequence of alternating contraction and relaxation of the atria and ventricles in order to pump blood throughout the body. It starts at the beginning of one heartbeat and ends at the beginning of another.

- 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

Definition: The cyclical changes that take place in the heart during each beat (one systole and. one diastole) Duration for one cycle = 0.8 sec. Phases: Atrial systole -0.1 sec. Atrial diastole- 0.7 sec. Ventricular systole – 0.3 sec.
