The most common fetal heart rate pattern consistent with uterine rupture is

Comprehensive and Detailed Explanation From Exact Extract (NCC-Referenced Sources)

According to AWHONN, Simpson, and NCC C-EFM physiologic competencies, uterine rupture commonly presents with:

Sudden prolonged deceleration

Recurrent variables

Fetal bradycardia

Possible loss of station, vaginal bleeding, maternal pain

AWHONN specifically lists:

“Prolonged deceleration is the most common initial fetal sign of uterine rupture.”

Absent variability can occur later, but it is not the most common initial pattern.

“Loss of uterine pressure” refers to loss of toco signal, not a fetal heart rate characteristic.

Therefore, NCC-validated interpretation: prolonged and variable decelerations.
