Overview
Cannon a waves are waves seen occasionally in the jugular vein of humans with certain cardiac arrhythmias. When the atria and ventricles contract simultaneously, or when the right atrium contracts against a closed tricuspid valve, the blood will be pushed against the AV valve, and a very large retrograde pressure wave travels up the jugular vein[1][2].
