doctordconline: Jugular Vein Pressure (JVP) Guys do you how to measure JVP? Waves a - presystolic; produced by right atrial contraction. c - bulging of the tricuspid valve into the right atrium during ventricular systole (isovolumic phase). v - occurs in late systole; increased blood in the right atrium from venous return. Descents x - a combination of atrial relaxation, downward movement of the tricuspid valve and ventricular systole. y - the tricuspid valve opens and blood flows into the right ventricle. The a and v waves can be identified by timing the double waveform with the opposite carotid pulse. The a wave will occur just before the pulse and the v wave occurs towards the end of the pulse. Distinguishing the c wave, x and y descents is an almost impossible task. #JVP #jugularvein #blood #heart #cardiology #cardiologist #usmle #university #usmlestep1 #usmlestep2 #doctor #doctordconline #nhs #nurse #nursing #hospital #patient #bloodpressure #pathology #physiology #medlife #medicine #amc #plab @doctordconline
