“…Morphological changes in the jugular pulse can help in the detection of haemodynamic disturbances in the right heart. Right ventricular pressure overload (Luisada, 1954;Gibson and Wood, 1955;Kitchin and Turner, 1964;Wood, 1968), tricuspid valvular disease (Muller and Shillingford, 1954;Gibson and Wood, 1955;Hartnan, 1960;Kitchin and Turner, 1964), atrial septal defect (Reinhold, 1955;Haroutunian et al, 1958;Tavel et al, 1968), and constrictive pericardial disease (Lisa et al, 1972) have been described as having characteristic changes in pulse contour. Recording a simultaneous phonocardiogram has allowed use of the jugular pulse in timing the right-sided third and fourth heart sounds (Tavel, 1972), the closure of the pulmonary valve, and the opening of the tricuspid valve (peak of 'V' wave) to assess the presence and degree of pulmonary hypertension (Hartman, 1960;Bamboa et al, 1965;Burstin, 1967).…”
