In spite of numerous technical advances in cardiovascular diagnosis, the bases for determination of the need for diagnostic tests and therapy and for evaluation of the response to therapy often remain the history and bedside physical findings. The complete cardiovascular examination includes evaluation of the arterial pulsations, the precordial pulsations, and cardiac auscultation. The correct interpretation of the jugular venous pulse is an integral part of the examination. The jugular venous pulsations reflect the systolic and diastolic hemodynamics of the right atrium and, in the absence of obstruction of the tricuspid valve, of the right ventricle as well. When correctly interpreted, the jugular venous pulsations provide information about right ventricular hemodynamics and important clues to the diagnosis. Instead of trying to find the classically described A and V waves in normal people, one should look for the systolic collapse of the normal jugular venous pulse. When one is thoroughly familiar with the normal variations, the few common abnormalities are easy to appreciate.
尽管心血管诊断技术取得了诸多进展，但确定诊断检查和治疗需求以及评估治疗反应的依据往往仍然是病史和床边体格检查结果。完整的心血管检查包括评估动脉搏动、心前区搏动和心脏听诊。正确解读颈静脉搏动是检查的一个组成部分。颈静脉搏动反映右心房的收缩和舒张血流动力学，在无三尖瓣梗阻时，也反映右心室的血流动力学。正确解读时，颈静脉搏动可提供有关右心室血流动力学的信息及重要的诊断线索。不应试图在正常人中寻找经典描述的A波和V波，而应寻找正常颈静脉搏动的收缩期塌陷。当对正常变异非常熟悉时，少数常见异常就很容易识别。
