Does fragmented QRS evaluation identify myocardial scar and depolarization abnormalities in patients with coronary artery disease?
This review highlights the role of fragmented QRS as an underutilized electrocardiographic marker for identifying myocardial scar and depolarization abnormalities in coronary artery disease.
The electrocardiogram is the mainstay approach for diagnosing a myocardial infarction (MI). The diagnosis of an old MI and the identification of myocardial scar via the electrocardiogram are difficult because there are no other specific signs for a non-Q-wave MI. In this article, we will review the fragmented QRS and its role in identifying myocardial scar and depolarization abnormalities in patients with coronary artery disease.
