The symptoms of the<unk>  can vary due to the underlying problems that associate / lead to the<unk> , and the features of<unk>  reflects the other manifestations of these diseases. Bradycardia is usually the first symptom of<unk>  to be detected in utero. Due to the<unk>  in the atrioventricular node, less electric signals move from the sinoatrial node to the bundle of his and its right and left branches, leading to a lower heart rate. The atrioventricular<unk>  can be first degree or much more severe like a complete atrioventricular<unk>  (third degree). In addition, several changes in the ECG can be detected. Other manifestations of the<unk>  can be related to the impact of the maternal autoantibodies in the autoimmune-mediated<unk> . Fibrosis of the myocardium (Endocardial fibroelastosis) (EFE) is the obvious one and it occurs due to the damage caused by the maternal autoantibodies to the cardiac tissue of the fetus, and can lead to death in some cases. However, it is not a common feature of<unk> . Another rare symptom that might accompany the autoimmune<unk>  is the disorder in the valvular function, and this happens due to the damage in the papillary muscles as a result of the maternal autoantibodies.
