Kussmaul's Sign and Friedreich's Sign on Neck Examination A middle-aged M with unknown PMH presents with dyspnea. What 2 eponymous JVP findings are demonstrated in the video? Most likely diagnosis? What is that small blue-colored spot on the skin (middle chest, lower part of screen) that might suggest the underlying cause? Kussmaul's (JVP rise w inspiration) + Friedreich's (sharp/deep Y-descent) + XRT tattoo = constrictive pericarditis 2/2 remote XRT. Pt was amazed - he hadn't disclosed hx of Hodgkin's (hospitalized for unrelated problem). "You figured that out just by looking at me?"
