Cannon A wave. Cannon A waves, or cannon atrial waves, are waves seen occasionally in the jugular vein of humans with certain cardiac arrhythmias.When the atria and ventricles happen to contract simultaneously, the right atrium contracts against a closed tricuspid valve, resulting in back pressure into the venous system that can be seen in the jugular venous pulse as a high-amplitude "cannon ...
Becker's sign, or Becker's phenomenon, is the presence of visible (through an ophthalmoscope) pulsation of retinal arteries, found in patients with aortic insufficiency or Graves' disease. [1] [2] The sign was named after Otto Heinrich Enoch Becker. [3]
