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).
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.
The contraction of the heart chambers in a regular cycle is called systole
A rhythmic contraction refers to a repeated pattern of muscle contractions at regular intervals. This can occur in various muscles in the body, including the heart muscle during the cardiac cycle. Rhythmic contractions are important for fundamental physiological processes such as pumping blood or generating movement.
no
The R wave of the ECG is most closely associated with the depolarization of the ventricles during the cardiac contraction cycle, specifically with the QRS complex. This represents the initiation of ventricular contraction.
A business cycle.
The contraction phase of the cardiac cycle is called systole. This is when the heart muscle contracts to pump blood out of the heart and into the circulatory system.
Similarly, a period of recession occurs at the start of the contraction phase.
