Complete heart block.
Complete heart block (CHB) occurs when atrial impulses are not conducted to the ventricles. It occurs in association with many conditions, including acute myocardial infarction. In the setting of acute myocardial infarction (MI), certain characteristic conduction disturbances tend to precede development of CHB. Knowledge of these disturbances provides rational indications for emergency temporary pacing of acute MI patients.
