Transient synchronous intrapartum late deceleration patterns of concordant twins due to maternal-related etiologies

Abstract

An unusual case is presented in which intrapartum electronic fetal heart rate (FHR) monitoring of concordant monochorionic twins at 39 weeks gestation revealed two separate occurrences of transient synchronous repetitive late deceleration patterns of both fetal heart rates. Both episodes were considered due to correctable maternal-related etiologies. Each of these occurrences resolved immediately with correction of the respective underlying etiologies, and the subsequent FHR tracings were reactive.
