Arterial Supply to the Atrioventricular Node: Anatomical Variability and Clinical Implications
Atrioventricular block (AVB) resulting from injury or ischaemia of the atrioventricular node (AVN) artery remains a key concern in inferior MI and procedures near the AVN. Given that ECG findings alone may be insufficient to reliably predict AVB occurrence or reversibility, anatomy-based risk assessment is essential. H...
