Conduction disturbances and paroxysmal atrial fibrillation during acute inferior myocardial infarction

Associated symptoms and conduction disturbances are reported during acute inferior myocardial infarction. Differentiation of right coronary artery from left circumflex artery occlusion may be difficult since both can present an electrocardiographic pattern of inferior myocardial infarction. Paroxysmal atrial fibrillation is considered a frequent complication of acute myocardial infarction and the patients with paroxysmal atrial fibrillation probably should be targeted for earlier and more aggressive treatment. These patients in the thrombolytic era have a better overall outcome than counterparts in the prethrombolytic era. We describe a case of conduction disturbances and paroxysmal atrial fibrillation in a 51-year-old Italian man with acute inferior myocardial infarction and right coronary artery stenosis.
