Heart Cycle

The complete round of cardiac systole and diastole with the intervals in between.

Heart cycle. The period of contraction that the heart undergoes while it pumps blood into circulation is called systole. The cardiac cycle refers to the pattern of contraction and relaxation of the heart during one complete heartbeat. When the cardiac muscle myocardium relaxes the blood carried by the veins fills the heart cavities atriums and ventricles.

The period of relaxation is called diastole. A Practice of Anesthesia for Infants and Children Fourth Edition 2009 Related terms. The human heart beats over 100000 times per day.

It starts at the beginning of one heartbeat and ends at the beginning of another. A heart cycle corresponds to one heartbeat. In each cardiac cycle the heart contracts systole.

Contraction of the heart muscle is known as systole and. Other articles where Cardiac cycle is discussed. This cycle can be divided into two basic phases.

The period of time that begins with contraction of the atria and ends with ventricular relaxation is known as the cardiac cycle. I raise awareness and funding for The American Heart Association and Rotary International with a focus on teaching children the benefits of a healthy and active lifestyle to help prevention of diseases like heart disease and stroke. For perspective the average humans heart will go through the cardiac cycle more than two billion time in its lifetime.

CCL is defined as the succession of atrial and ventricular electromechanical events. The heart undergoes two main events during a complete cardiac cycle diastole and systole. The cardiac cycle is the performance of the human heart from the ending of one heartbeat to the beginning of the next.
