Cannon a wave - definition, causes, pathophysiology

Cannon A waves are a type of waveform that can sometimes be observed in the JVP tracing. They are characterized by a sudden and forceful upward movement of the waveform, which is thought to be caused by the contraction of the right atrium against a closed tricuspid valve. Cannon A waves are often seen in conditions where there is an interruption of the normal electrical conduction system of the heart, such as in complete heart block or ventricular tachycardia. They can also be seen in conditions where there is an obstruction to the blood flow from the right atrium to the right ventricle, such as in tricuspid stenosis or pulmonic stenosis.
