Atrioventricular (AV) block is a condition where the conduction between the atria and ventricles of the heart is impaired, leading to a delay or complete interruption of electrical signals. This is clinically significant as it can result in bradycardia, syncope, or even heart failure, necessitating close monitoring and potential intervention. A common association is with myocardial infarction, particularly inferior wall ischemia, which can exacerbate the block.
