hereditary disease atrioventricular dissociation https://www.malacards.org/card/atrioventricular_dissociation ICD9:426.89 Impaired conduction of cardiac impulse that can occur anywhere along the conduction pathway, such as between the sinoatrial node and the right atrium (sa block) or between atria and ventricles (av block). Heart blocks can be classified by the duration, frequency, or completeness of conduction block. Reversibility depends on the degree of structural or functional defects. icd11.foundation:268503599 atrioventricular dissociation (disease) MEDGEN:2496 atrioventricular dissociation OMIM:209600 SCTID:50799005 atrioventricular dissociation (disease) HP:0011709 MONDO:0008848 UMLS:C0004331 MESH:D006327 cardiac conduction defect
