Electricity is chaotic, and we normally need to constrain it to wires and circuits to make use of it. Scientists in Europe and Canada have now managed to guide sparks through thin air and even around ...

Tissue Doppler Imaging (TDI), including Color TDI to assess direction and timing of myocardial function, and pulsed wave TDI for velocity ... and ease-of -use for ultrasound guided regional ...

Methods Central and peripheral pulse wave velocity (PWV) was measured using Doppler ultrasound and calculated by the ‘foot to foot’ method before and after exercise. PWV was initially measured at rest ...

inferior vena cava ultrasound, (3) venous excess ultrasonography (VExUS), and (4) pulsed wave Doppler of the left ventricular outflow track to estimate stroke volume (i.e., velocity time integral).
