I think hypokalemia is incorrectly listed as one of the causes of first degree AV block. My ECG handbook says it is hyperkalemia that can cause first degree AV block (and some internet sources confirm this).
First-degree AV block occurs in fewer than 15% of patients with acute MI admitted to coronary care units. His bundle electrocardiographic studies have shown that, in most of these patients, the AVN is the site of conduction block. AV block is more common in the setting of inferior MI.
