The JVP has a single waveform rather than a double waveform
It can be diagnosed without an ECG
It is strongly associated with hypercholesterolaemia
It carries no increased mortality compared to normal sinus rhythm
The JVP characteristically has giant V waves
The JVP has a single waveform rather than a double waveform
A superb question! The JVP normally has an “a” wave and a “v” wave. These are from atrial and ventricular contraction respectively. Hence in AF where the atrium is fibrillating you get no a wave.
Giant V waves occur in tricuspid regurgitation.
You need an ECG to diagnose AF because things like ectopics can cloud the matter (e.g. frequent atrial ectopics).
