Jugular vein is a natural non invasive right heart catheter inserted permanently in the right atrium . It faithfully reflects the right heart hemo-dynamics during every heart beat.
The information you gather is dependent upon the time you spend and mind you you apply on this biological catheter.Wenke back did so nicely he was able to identify progressive a and c interval and a drop of c wave before even the ECG machine was invented.
The following table illustrates the difference

Looking at the neck veins for hours together has been a favorite pastime of our cardiology ancestors.Thanks to those sharp intellect , that has led us to this height of cardiovascular revolution. Measuring JV pressure by itself was considered a big science. Putting a patient in 45 degrees , marking the sternal angle, identify the oscillating venous column, measuring the vertical distance etc . . .
Now in 2010 , with bedside hand-held echo one can rapidly rule out an elevated central venous pressure by imaging the jugular vein directly . Here is an article from American heart journal
