Why the study?
Does an abnormal SAECG predict sustained ventricular arrhythmias and/or death in patients with nonischemic dilated cardiomyopathy?
Does an abnormal SAECG predict sustained ventricular arrhythmias and/or death in patients with nonischemic dilated cardiomyopathy?
An abnormal SAECG is a significant prognostic marker for arrhythmic events and death in patients with nonischemic dilated cardiomyopathy.
Abnormal SAECG may aid risk stratification in nonischemic cardiomyopathy; hypothesis-generating and requires prospective validation before guiding therapy.
Patients with an abnormal SAECG had a statistically significant increase in sustained ventricular arrhythmias and/or death than did patients with a normal SAECG or BBB. This study demonstrates that an abnormal SAECG is a marker of past and future arrhythmic events in patients with nonischemic dilated cardiomyopathy. In contrast, patients with a dilated cardiomyopathy with a normal SAECG have an excellent prognosis with adverse outcome only from progressive heart failure.
