Complete heart block is most likely due to failure of conduction at the:
Show answer and explanation
Correct answer: AV node (atrioventricular node)
Complete heart block results from impaired conduction through the AV node, severing the electrical link between atria and ventricles. Consequently, the atria and ventricles beat independently at their respective intrinsic rates.
