Resting full-cycle ratio
WebNov 25, 2024 · The resting full-cycle ratio (RFR) is a unique non-hyperemic index which is calculated as the point of absolutely lowest distal pressure to aortic pressure during entire cardiac cycle. It is unclear whether RFR may detect functionally significant coronary stenosis that cannot be detected with other resting indices due to differences in the cardiac cycle. WebThe advent and successful development of instantaneous wave free ratio (iFR) has led to the burgeoning of other resting pressure-derived physiological indices such as the resting …
