Role of QRS fragmentation in 12-lead surface ECG in prediction of isolated epicardial coronary artery ectasia and its anatomical distribution in patients without acute coronary syndromes [PDF]

The Egyptian Heart Journal, 2020
Background Coronary artery ectasia (CAE) is a form of abnormal coronary artery lumen dilatation associated with epicardial flow disturbances and microvascular dysfunction.

Cardiac Rehabilitation Improves the QRS Fragmentation in Patients With ST Elevatıon Myocardial Infarction [PDF]

Journal of Cardiovascular and Thoracic Research, 2015
Introduction: We aimed to evaluate the effect of exercise-based cardiac rehabilitation (CR) on the fragmented QRS (fQRS) in patients with ST elevation myocardial infarction (STEMI).

European Heart Journal Supplements, 2021
Abstract Aims Fragmented QRS (fQRS), defined as the presence of additional peaks within the QRS complex (<120 ms) in at least two contiguous leads, was considered as a pattern of fibrosis. However, fQRS can also be detected during pre-participation cardiovascular screening.

Subtle QRS changes are associated with reduced ejection fraction, diastolic dysfunction, and heart failure development and therapy responsiveness: Applications for artificial intelligence to ECG

Annals of Noninvasive Electrocardiology, 2022
Background Since the last century, the electrocardiogram (ECG) remains the non‐invasive test, that is, most easily accessible, feasible, and inexpensive for cardiology assessment.
