A) at the same time as closure of the semilunar valves; at the same time as closure of the atrioventricular valves
B) during the isovolumetric contraction phase of the cardiac cycle; during the isovolumetric relaxation phase of the cardiac cycle
C) at the same time as the P-wave of the electrocardiogram; at the same time as the T-wave of the electrocardiogram
D) when the the ventricle reaches end-systolic volume; when the ventricle reaches end-diastolic volume
E) during the middle of the phase of ventricular ejection; just before the semilunar valve opens
