[vc_row css=”.vc_custom_1592017000151{background-color: #fff9f9 !important;}”][vc_column][vc_column_text]The normal jugular venous pulse is best evaluated via the right internal jugular vein, and is characterized by three peaks and two troughs. The first peak, called the a wave, results from atrial contraction during late diastole. Next, during early systole, ventricular contraction triggers closure of the tricuspid valve, producing the c wave (not visible at the bedside). In mid-systole, a combination of atrial relaxation and descent of the atrial floor during ventricular contraction results in the x descent. The third peak, the v wave, occurs as a result of atrial filling during late\u00a0systole. Finally, passive ventricular filling in early diastole produces the y descent. The most conspicuous features of the venous pulse are the troughs, which generate obvious, aggressive inward movements of the skin. In the normal jugular venous waveform, the x descent is deeper than the y descent. Compared to the arterial pulse, the venous pulse involves a more diffuse area of the neck. It varies with patient positioning, respiratory cycle, and abdominal pressure (abdominojugular reflux). The normal venous pulse is not palpable.\u00a0<\/span>
