Variability in the transtricuspid gradient by continuous wave Doppler echocardiography.
In order to examine the day-to-day variability in the tricuspid regurgitant velocity jet and to determine the degree of physiological changes under exercise and volume loading, repeated echo cardiographic Doppler measurements in 1 single subject were performed.
