Abstract
CARDIAC arrhythmias are frequent, serious complications of acute myocardial infarction1 2 3 and are associated with a 7 to 17 per cent increase in mortality.2 , 4 The extent to which arrhythmias are a direct cause of death in acute myocardial infarction has been estimated from clinical and pathological studies,5 6 7 but there has been little electrocardiographic documentation of the immediate preterminal rhythms. Documentation of possible transient disturbances of rhythm before the terminal arrhythmias has also been limited. Availability of a continuous electrocardiographic monitoring device has made it possible to detect and document the arrhythmias that follow myocardial infarction. The cardiac rhythm of 30 patients . . .
