Ventricular ejection is the phase of the cardiac cycle during which the ventricles contract and pump blood out of the heart. Specifically, the right ventricle sends deoxygenated blood to the lungs through the pulmonary artery, while the left ventricle pumps oxygenated blood to the rest of the body via the aorta. This process is crucial for maintaining circulation and ensuring that tissues receive the oxygen and nutrients they need. The ejection fraction, a key measure of heart function, indicates the percentage of blood ejected relative to the total volume of blood in the ventricle at the end of diastole.
What else can I help you with?
What is the Resistance to flow or impedance to ventricular ejection referred to as?
Afterload
What does the medical abbreviation LVEF mean?
Left Ventricular Ejection Fraction
What is the use of the valves?
The atrioventricular valves are used to stop blood from flowing back into the atrium during ventricular ejection of blood during ventricular contraction.
What is normal left ventricular ejection fraction as a percentage?
According to my Cardiologist 50-70% is normal.
What is the period of isovolumetric contraction is immediately followed by?
The period of isovolumetric contraction is immediately followed by the period of ventricular ejection in the cardiac cycle. During isovolumetric contraction, the ventricles contract while all valves are closed, and this is followed by the opening of the semilunar valves to allow blood to be ejected from the heart during ventricular ejection.
If ejection fraction is 37 percent is it called left ventricular dysfunction dysfunction?
If EF is 37% is it possible to make lung transplantation?
What is left ventricular perfusion?
Left Ventricular dysfunction-A condition in which the LEFT VENTRICLE of the heart was functionally impaired. This condition usually leads to HEART FAILURE; MYOCARDIAL INFARCTION; and other cardiovascular complications. Diagnosis is made by measuring the diminished ejection fraction and a depressed level of motility of the left ventricular wall.
What happens to the volume of blood in the ventricle during the period of isovolumetric contraction?
Both ventricular contraction and atrial diastole take place.
The amount of blood pushed out of the ventricle with each contraction is called?
Stroke-Volume
What does LVEF mean in a stress test?
LVEF stands for Left Ventricular Ejection Fraction, which is a measurement of how well the left ventricle of the heart is pumping blood out to the body. In a stress test, LVEF provides information on the heart's efficiency and function during periods of increased physical stress. A normal LVEF percentage is typically between 55-70%.
What Types of ejection systems are used in injection molding?
sleeve ejection,blade ejection,srriper plate ejection,pin ejection,valve ejection
What does the medical abbreviation global LVEF mean?
The medical abbreviation "global LVEF" stands for Global Left Ventricular Ejection Fraction. It is a measure of the heart's pumping ability and is used to assess cardiac function. A normal LVEF value typically ranges from 55% to 70%, indicating good heart function. This measurement is crucial in diagnosing and managing various heart conditions.
