title: Cannon waves with A-V association.
abstract: Under appropriate circumstances, cannon waves can occur in the presence of A-V associated rhythms. Presented here is a case of first degree A-V block with cannon waves. Recognition of these waves and their behavior aided in diagnosing the patient's rhythm. The cannon waves were documented by jugular venous pulse recordings.
