Which of the following would increase cardiac output? (Select multiple) Decreased Heart Rate (with no changes to stroke volume) Mitral valve prolapse and blood flow into the atrium Increased Heart Rate (up to a point) Haemorrhage Increased Stroke Volume Decreased Stroke Volume How do we calculate stroke volume? ESV-EDV End systolic volume - End diastolic volume (SV / EDV) · 100 SV - Stroke Volume EDV - End Diastolic Volume HR x SV Heart Rate x Stroke Volume EDV-ESV End diastolic volume - End systolic volume Cardiac output is held constant. Cardiac output at rest matches cardiac output during exercise. True False Which occurs first in a heartbeat? Ventricular Systole Atrial Systole Atrial and ventricular systole occurs simultaneously Which of the following occur during ventricular systole? (Select multiple) The pressure in the ventricles is higher than in the atria The atrioventricular valves are open The pressure in the atria is higher than in the ventricles The atria contract The ventricles contract The semilunar valves are open Select all that occur during ventricular systole. (Select multiple) The atrioventricular valves are open which allows blood to enter the ventricles from the atria. The semilunar valves remain closed throughout systole to prevent backflow of blood into the ventricles. The atrioventricular valves close to prevent backflow of blood into the atria. The semilunar valves open to allow blood to flow into the large arteries. What is cardiac output (CO)? The volume of blood that passes through the coronary vessels each minute The volume of blood pumped by one ventricle in one minute The volume of blood that remains in the heart after ejection The volume of blood pumped in one beat Match the portion of the ECG to the description - A. B. C. D. E. F. P Wave - A. B. C. D. E. F. QRS Complex - A. B. C. D. E. F. T Wave - A. B. C. D. E. F. Aortic Semilunar Valve - A. B. C. D. E. F. P-R Segment - A. B. C. D. E. F. S-T Segment A. Ventricular Repolarization B. Prevents blood from flowing from the aorta into the left ventricle C. Ventricular Contraction D. Atrial Depolarization E. Ventricular Depolarization Atrial Repolarization F. Atrial contraction When would the ventricles contain their end diastolic volume? Is volumetric contraction (Early Ventricular Systole) The beginning of atrial Systole Is volumetric relaxation (Early Ventricular Diastole) The end of ventricular ejection (Late Ventricular Systole) During which phase of the cardiac cycle do the atria fill the ventricles? Atrial Systole Is volumetric contraction (Early Ventricular Systole) Is volumetric relaxation (Early Ventricular Diastole) Ventricular ejection (Late Ventricular Systole)
