Physiological Changes in QRS Fragmentation in Athletes and Nonathletes without Cardiac Disease [PDF]

open access: yesJournal of Clinical Medicine
Background/Objectives: QRS fragmentation has not been linked with increased mortality in individuals without known cardiac disease. We aimed to investigate the physiological determinants of QRS fragmentation in individuals without cardiac disease ...

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

open access: yesJournal 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).

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

open access: yesAnnals 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.

Electrocardiographic variables associated with underlying Brugada syndrome or drug‐induced Type 1 Brugada pattern in patients with slow/fast atrioventricular nodal reentrant tachycardia

open access: yesJournal of Arrhythmia, 2022
Background The coexistence of clinical atrioventricular nodal reentrant tachycardia (AVNRT) and drug‐induced type 1 Brugada pattern (DI‐Type 1 BrP) has been previously reported.
