[vc_row css=”.vc_custom_1592015955711{background-color: #fff9f9 !important;}”][vc_column][vc_column_text]Kussmaul\u2019s sign is defined as a\u00a0paradoxical rise in jugular venous pressure during inspiration. Decreased intrathoracic pressure during inspiration normally leads to an increase in venous return to the right side of the heart, with an associated decrease in jugular venous pressure. When there is impaired filling of the right ventricle, the jugular veins instead become engorged. Causes of Kussmaul\u2019s sign include right ventricular infarction, severe right ventricular failure, restrictive cardiomyopathy, constrictive pericarditis, and tricuspid stenosis.<\/span>

Patient 1:<\/h1>\n

This patient developed constrictive pericarditis many years after external beam radiation therapy to the chest. The video demonstrates the defining feature of Kussmaul’s sign, a paradoxical rise in jugular venous pressure with inspiration. <\/span><\/p>\n
