Ventricular Depolarization Abnormalities and Their Role in Cardiac Risk Stratification - A Narrative Review.
Rev Cardiovasc Med
January 2025
Department of Cardiovasculair Sciences, KU Leuven, 3000 Leuven, Belgium.
Ventricular depolarization refers to the electrical activation and subsequent contraction of the ventricles, visible as the QRS complex on a 12-lead electrocardiogram (ECG). A well-organized and efficient depolarization is critical for cardiac function. Abnormalities in ventricular depolarization may indicate various pathologies and can be present in all leads if the condition is general, or in a subgroup of anatomically contiguous leads if the condition is limited to the corresponding anatomic location of the heart.

Background: Hypertension is a leading cause of cardiovascular disease and premature death worldwide, and it puts a heavy burden on the healthcare system. Therefore, it is very important to detect and evaluate hypertension and related cardiovascular events to enable early prevention, detection, and management. Hypertension can be detected in a timely manner with cardiac signals, such as through an electrocardiogram (ECG) and photoplethysmogram (PPG) , which can be observed via wearable sensors.

Cardiac metabolism relies on glycogen conversion by glycolysis. Glycolysis intersects fatty acid oxidation and often directs a signal crosstalk between redox metabolites. Myocardium with ischemia/reperfusion significantly diverts from normal metabolism.

Karabuk University Faculty of Medicine, Department of Cardiology, Karabuk, Turkey Karabük University Karabuk University Faculty of Medicine Department of Cardiology Karabuk Turkey.
Background: The association of fragmented QRS (fQRS) with many cardiac pathologies such as cardiac fibrosis has been described previously. Paraaortic adipose tissue (PAT) is thought to be associated with many cardiac diseases and there is only one publication on its echocardiographic evaluation.
Aims: To describe the possible relationship between fQRS and PAT.
