b) which electrical event immediately precedes the increase in ventricular pressure?
c) what is happening when the pressure of the left ventricle is lowest?

Conclusion: m∠spt + m∠tpu = 90° which of the statements supports the conclusion from the diagram and the given information. vertical angles are equal in measure. perpendicular lines meet to form right angles. adjacent angles whose exterior sides are perpendicular rays are complementary. adjacent angles whose exterior sides are perpendicular rays are supplementary.
