What is the Medical term meaning decrease of heart muscle?
Diastole is the relaxation phase of the heart.
Which phase of the heartbeat does the heart fill with blood?
during diastolic phase the chambers of heart get filled with blood systolic phase and diastolic phase are the phases oh heartbeat and diastolic phase is also known as resting phase.
Does the length of cardiac cycle decrease with more rapid heart rate?
The diastolic phase
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.
What is meant by systole and diastole?
The ventricles of heart have two states: systole(contraction) and diastole (relaxation). During diastole blood fills the ventricles and during systole the blood is pushed out of the heart into the arteries. The auricles contract anti-phase to the ventricles and chiefly serve to optimally fill the ventricles with blood.http://www.answers.com/systole
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...
When preforming CPR what is known as the relaxation phase of the heart?
The relaxation phase of the heart is when there is no compression pressure on the heart.
The relaxation phase of the heartbeat is called?
The relaxation phase of the heartbeat is called diastole. During diastole, the heart ventricles relax and fill with blood in preparation for the next contraction.
What is the Medical term meaning decrease of heart muscle?
Diastole is the relaxation phase of the heart.
What is the name given to contraction phase of the cardiac 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.
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.
What portion of the cardiac cycle is shortened by this more rapid heart rate?
The diastolic phase is shortened by a more rapid heart rate. This is the phase when the heart muscle relaxes and fills with blood. A faster heart rate reduces the time available for the heart to refill, impacting cardiac output.
What happens during the T wave of the cardiac cycle?
During the T wave of the cardiac cycle, the ventricles of the heart repolarize, meaning they reset their electrical charge in preparation for the next heartbeat. This phase represents the relaxation and recovery of the heart muscle after contraction.
What is the term that defines the relaxation phase of the heartbeat?
diastole
What phase of the cardiac cycle is the heart in when all four valves of the heart are closed and ventricular pressure is building but is not yet great enough to open a valve?
That phase is called as isovolumetric contraction phase.
What is the relaxing phase of the cardiac cycle?
The relaxing phase of the cardiac cycle is called diastole. During diastole, the heart chambers (atria and ventricles) relax, allowing them to fill with blood. This is followed by the contracting phase called systole.
What phase of the heart cycle is the blood pumped out of the heart?
it is pumped out of the lungs
