In addition to ventricular arrhythmias, various forms of supraventricular arrhythmias (SVA) and atrioventricular (AV) and intraventricular (IV) conduction disturbances occur also in acute myocardial infarction (AMI). In the setting of AMI, SVA may be caused by relevant atrial ischemia or infarction. SVA complicate the course especially that of inferior, posterior and lateral AMI. ⋯ The major cause of death in these patients are heart failure, cardiogenic shock and malignant ventricular arrhythmias due to larger AMI, significant reduction of left ventricular function and advanced coronary heart disease. Complex SVA as well as serious AV and IV conduction disturbances are usually considered as markers, but not as independent predictors for both increased hospital mortality and in some cases also for that of posthospital mortality. Their occurrence in AMI may help to identify the patients at great risk who require a very intensive treatment including aggressive management of extensive coronary heart disease. (Ref. 62.)

In the setting of AMI, SVA may be caused by relevant atrial ischemia or infarction. SVA complicate the course especially that of inferior, posterior and lateral AMI, SVA occur frequently also in the right ventricular myocardial infarction and in pericarditis. ⋯ The major cause of death in these patients are heart failure cardiogenic shock and malignant ventricular arrthythmias due to larger AMI, significant reduction of left ventricular function and advanced coronary heart disease.
