“Sleep Disordered Breathing and ECG R-wave to Radial Artery Pulse Delay, The Multi-Ethnic Study of Atherosclerosis”

Electrocardiography R-wave to Radial artery pulse delay (RRD) represents pulse transit time inclusive of pre-ejection period (PEP) and arterial pulse propagation time. RRD is proposed to largely reflect arterial stiffness when PEP is accounted for (shorter RRD = higher arterial stiffness). Sleep disordered breathing (SDB) causes intermittent hypoxemia and sympathetic activation, which negatively influence vascular function. We aimed to examine the association of measures of SDB with RRD.
