Overview
Acute myocardial infarction (MI) remains the leading cause of mortality all over the world. Electrical conduction abnormalities commonly complicate acute myocardial infarction, leading to a further rise in long and short term morbidities and mortality rates. [1] Different types of conduction abnormalities can follow MI, with bradyarrhythmias and atrioventricular (AV) block representing the most common. Other post-MI conduction abnormalities include supraventricular arrhythmias and ventricular arrhythmias.
