摘要

•Improve phasic calibration of fluid-filled catheters by accounting for oscillations•Retrospective analysis of 2886 drift check tracings from 16 countries•Majority of tracings improve when removing oscillations, most underdamped•Neglecting oscillations leads to biased estimates of equalization parameters
