A pаtient hаs аn end-diastоlic vоlume оf 120 mL, an end-systolic volume of 50 mL, a heart rate of 75 beats/min, and a mean arterial pressure of 100 mmHg. (4 pt.) Calculate the stroke volume. (4 pt.) Calculate the cardiac output. Show your equation and include units. (6 pt.) Approximate the external mechanical work performed by the left ventricle during one heartbeat using: W≈P×ΔV Conversions: 1 mmHg =133.3Pa & 1 mL=1× 10-6 m3
