Schematic for the measurement of brachial-ankle pulse wave velocity (baPWV). baPWV is estimated as the length between the sternal notch and the ankle (LSA) minus the sternal notch to brachium (LSB), as determined by body surface measurements or height-based formulas, divided by the time delay between brachial and ankle waveforms (ΔTBA). Note: Solid line denotes effective path length.
