1. History & Physical/Cardiology Which of the following conditions would cause a positive Kussmaul's sign on physical examination? Answers A. Left ventricular failure B. Pulmonary edema C. Coarctation of the aorta D. Constrictive pericarditis - (u) A. Left ventricular failure results in the back-up of blood into the left atrium and then the pulmonary system so it would not be associated with Kussmaul's sign. (u) B. Pulmonary edema primarily results in increased pulmonary pressures rather than having effects on the venous inflow into the heart. (u) C. Coarctation of the aorta primarily affects outflow from the heart due to the stenosis resulting in delayed and decreased femoral pulses; it has no effect on causing Kussmaul's sign. (c) D. Kussmaul's sign is an increase rather than the normal decrease in the CVP during inspiration. It is most often caused by severe right-sided heart failure; it is a frequent finding in patients with constrictive pericarditis or right ventricular infarction.
