That forty-six-point difference between arms is not an equipment error, and it is the finding most likely to be dismissed as one. An aortic dissection begins when the innermost lining of the aorta tears. Blood at arterial pressure is driven into the wall itself, splitting the layers apart and creating a second, false channel that travels along the vessel.
