This physical exam sign is seen with AV dissociation — and results from right atrial contraction against a closed tricuspid valve. Cannon waves are associated with reduced RV compliance or elevated RV end-diastolic pressure ( Ali et al — Ann Noninvasic Electrocard 22:e12423, 2017 — and — Chen and Pel-Ying Pai — Circulation 119:e381, 2009 ).
