The evolution of prenatal diagnosis and treatment for fetal arrhythmias embarked on its journey in the 1980s, marked by Kleinman et al.’s pioneering report on prenatal diagnosis using M-mode echocardiography. Since then, various diagnostic methods, from fetal ultrasonography to fetal magnetocardiography, have emerged, each contributing to our understanding of fetal cardiac rhythm abnormalities. By employing a combination of these diagnostic modalities healthcare professionals can effectively classify rhythm abnormalities in fetuses, enabling tailored interventions. However, despite these advancements, diagnosing fetal arrhythmias remains a challenging task. At present, transabdominal fetal echocardiography has emerged as one of the mainstays for diagnosing fetal arrhythmias.7
