Calibrated jugular pulse tracings and cardiac catheterisation were performed on 50 consecutive patients with organic heart disease. Twenty normal adults had calibrated jugular pulse tracings and served as controls. The height of the jugular 'A' and 'V' waves was quantified as a percentage of a known displacement, rendering measurements independent of the amplification used in recording technique. A close correlation existed between the size of the calibrated jugular 'A' and 'V' waves and the actual magnitude of the right intra-atrial pressure changes (A wave, r = 0.72; V wave, r = 0.80). Patients who were free of pulmonary hypertension or tricuspid disease had calibrated 'A' and 'V' waves similar in height to the control population. An enlarged 'A' wave was usually associated with conditions restricting flow into the right ventricle. An enlarged 'V' wave generally indicated tricuspid regurgitation. These changes are often subtle and are not apparent in conventional venous tracings or at the bedside. We conclude that the calibrated jugular pulse tracings can accurately separate normal from abnormal venous waves and expand the diagnostic potential of the jugular pulse.
对50例连续的器质性心脏病患者进行了校准颈静脉搏动描记和心导管检查。20名正常成年人进行了校准颈静脉搏动描记并作为对照。颈静脉“A”波和“V”波的高度被量化为已知位移的百分比，使测量独立于记录技术中使用的放大倍数。校准后的颈静脉“A”波和“V”波的大小与右心房压力变化的实际幅度之间存在密切相关性（A波，r = 0.72；V波，r = 0.80）。无肺动脉高压或三尖瓣疾病的患者校准后的“A”波和“V”波高度与对照组相似。增大的“A”波通常与限制血液流入右心室的情况有关。增大的“V”波通常提示三尖瓣反流。这些变化往往很细微，在传统静脉描记图或床边检查中并不明显。我们得出结论，校准后的颈静脉搏动描记可以准确区分正常和异常静脉波，并扩大颈静脉搏动的诊断潜力。
