Phase of the cardiac cycle that shortens most in response to tachycardia?
diastolic
Coronary blood flow is greatest during what phase of the cardiac cycle?
diastolic
Does the length of cardiac cycle decrease with more rapid heart rate?
The diastolic phase
When does majority of the coronary artery fill?
The coronary artery fills during the diastolic phase of the cardiac cycle
What is occurring during the diastolic period?
Diastole is the phase in the cardiac cycle that allows filling of blood into the ventricle. It corresponds to the lower number in the blood pressure measurement. A normal upper limit of the blood pressure falls in the range less than 120/80 mm Hg. Above this value, it is considered pre-hypertension based on The Seventh Report of the Joint National Committee on Prevention, Detection, Evaluation, and Treatment of High Blood Pressure.During the diastolic period the ventricle is in the fifth phase of the cardiac cycle. This phase is termed isovolumetric relaxation which occurs immediately after the second heart sound. In this phase, all valves of the heart are closed. The volume of blood in the ventricle during this phase of the cardiac cycle remains constant. Following the fifth phase of the cardiac cycle is the rapid filling of blood into the ventricle. This cycle corresponds to the opening of the mitral and tricuspid valves located between the left and right atria and ventricle, respectively. The next phase of the cardiac cycle, called diastasis, is the longest phase of the cardiac cycle. In this cycle, the ventricle continues to fill with blood but at a much slower rate. The final phase of diastole corresponds to the first phase of the cardiac cycle. In this phase of the cardiac cycle, the atria contracts to provide additional filling of blood into the ventricle. After the final phase of diastole, the systolic phase of the cardiac cycle begins.
Identify the phase of the cardiac cycle to each of the following systolic pressure and diastolic pressure?
Systolic Pressure occurs during ventricular ejection.Diastolic Pressure occurs during ventricular relaxation.
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.
Which phase of the cardiac cycle is longest?
ventricular diastole
Which is the phase of cardiac cycle in which the auricles contract?
The auricles will contract during the systolic phase of the cardiac cycle. This is one of the numbers that is measured when a patient has their blood pressure taken.
When do the AV valve close during the cardiac cycle?
AV valves close during the systole phase of the cardiac cycle.
What is the alternating relaxation and contraction of the heart called?
Diastole is the relaxation phase. Systole is the contraction phase. If you put these phases together you have the Cardiac Cycle...
Which is the phase of cardiac cycle in whitch the auricles contract?
Systole is the correct answer
