Increased CVP (from high blood volume) B. Increased heart rate (by a positive chronotrope) C. Increased residual left ventricular volume (from low stroke volume) D. Weak ventricular muscle (from wall atrophy) E. Increased PWP (pulmonary wedge pressure) 9. When a vascular clamp on the abdominal aorta below the renal arteries for 30 minutes is abruptly released, which of the following quickly i ncreases? A. Total Peripheral Resistance B. Coronary Perfusion Pressure C. Left Ventricular After Load D. Slope of SA node phase 4 30 30 B A mmHg 20 20 mmHg 10. Swan-Ganz Pressure tracings. Which statement below correctly matches the corresponding tracing displayed on the right (i.e., does answer A match tracing “A”)? A. A decreased cardiac output will decrease this pressure 10 10 0 0 B. The vessels that have this pressure have an higher compliance than the vena cava 30 C. Left heart failure lowers this pressure 30 C D 20 mmHg D. Increased myocardial contractility can increase pulse pressure here mmHg 20 10 10 D 0 0
