What are the definition or meaning of diastole?
definiton or meaning of diastole : Refers to the phase of the cardiac cycle when the heart is relaxed. This phase of the cardiac cycle contributes to the lower number in blood pressure readings, called the "diastolic blood pressure." A value of greater than 90 on three or more different readings over time is used to define hypertension.
What are the two components of cardiac output?
Cardiac output is the actual amount of blood being pumped by the heart. The stroke volume of the heart determine the amount of work done by the heart.
How is cardiac output calculated?
It's the stroke volume times the heart rate.
What is cardiac ablation and what occurs?
Cardiac ablation is a procedure where they remove a faulty electrical pathway from the heart. They do this by inserting a is advance a flexible catheters into a blood vessel.
How would you define cardiac output?
Medically its the stroke volume times the heart rate, or --- just the amount of blood that the heart pumps in a minute.
What portion of the cardiac cycle is shortened by this more rapid heart rate?
The ventricular relaxation period.
What is the term that refers to the portion of the cardiac cycle when the ventricles contract and eject blood from the heart?
Systolic pressure
What does cardiac output do if the heart rate decreases?
Cardiac output = heart rate X stroke volume Thus, if the heart rate decreases so will the cardiac output, assuming the stroke volume is constant.
What is a complete cycle of a heart contraction and relaxation called?
Cardiac cycle, which is made up of atrial and ventricular systole and diastole.
What do you call the circulation of the heart to the lungs and back to the heart?
cardiac cycle
How does the heart contract or relax?
The heart contracts and relaxes during a cardiac cycle.
One complete heart beat is known as?
Cardiac Cycle
Each complete heart beat is called what?
cardiac cycle
As heart increases what would happen to cardiac cycle?
it repeats
How does acetylcholine affect the cardiac cycle?
Ach decreases the heart rate and the force of the contraction. This is done through signaling molecules, and how they have a different effect on the heart vs salivary glands is that they have different receptors but sometimes they have the same receptor just the internal machinery is different.
Function of the crdiaac tissues?
Cardiac tissue is the heart muscle and its function is to pump blood between the heart-lungs cycle and the heart-body cycle.
What is the graphic of heart sounds produced during the cardiac cycle?
Phonocardiogram
