1 Fetal heart rate reflects mutation burden and clinical outcome in twin probands with KCNQ1 mutations 
Annika Winbo, MD, PhD, Annika Rydberg, MD, PhD  HeartRhythm Case Reports  Volume 4, Issue 6, Pages (June 2018) DOI: /j.hrcr Copyright © 2018 Heart Rhythm Society Terms and Conditions

2 Figure 1 Consecutive recordings for 48 hours at 19 weeks' gestation revealed a lower mean fetal heart rate in twin II (95–128 beats per minute) compared to twin I (125–145 beats per minute).

3 Figure 2 Clinical presentations in the twin family pedigree. Available clinical data are given below the individuals. Females are indicated by circles; males are indicated by squares. Hatched symbols indicate deceased. HR = heart rhythm (in beats per minute); I = twin I; II = twin II; QTc = corrected QT interval (in milliseconds).
