  • Title: Regular cannon wave.
    Author: Ranjith MP, Shajudeen K, Prasanth S.
    Journal: Indian Heart J; 2016 Sep; 68 Suppl 2(Suppl 2):S291-S293. PubMed ID: 27751320.
    Abstract:
    A 52-year-old male with history of dilated cardiomyopathy was admitted with progressive dizziness and worsening dyspnea. His blood pressure was 100/60 with a regular pulse of 70 per minute. Jugular vein wave showed a prominent pulse like regular cannon waves. Cannon wave occurs in conditions with atrioventricular dissociation and right atrial contraction against a closed tricuspid valve. Large A waves are associated with reduced right ventricular compliance or elevated right ventricular end-diastolic pressure.
