The role of digitalis in acute myocardial infarction.

Digitalis is useful in the control of atrial tachyarrhythmias complicating acute myocardial infarction, whether or not congestive heart failure is present. The drug can also be helpful in patients in the subacute and chronic phases of myocardial infarction if congestive heart failure is present. Digitalis is not, however, the drug of choice in the treatment of patients with left ventricular dysfunction complicating acute myocardial infarction.
