Term Detail
MP term:abnormal atrioventricular node morphology
Synonym: abnormal atrio-ventricular node
Synonym: abnormal A-V node
Synonym: abnormal AV node
MP id: MP:0004114
Definition: any structural anomaly of the small nodular mass of specialized muscle fibers located in the interatrial septum near the opening of the coronary sinus; this node gives rise to the electrical connection between the atria and ventricles and responds to the sinoatrial node
Number of paths to term: 2
