Assessment of Noninvasive Methods to Identify Patients at Risk of Serious Arrhythmias After a Heart Attack

Summary

This study evaluates the usefulness of noninvasive tests of the structure of the heart and the nervous system controlling the heart. It will assess whether combining tests that evaluate heart structure with others that measure the nervous system controlling the heart will identify most patients who develop serious heart rhythm problems after a heart attack.
