Electrocardiographic Imaging of Repolarization Abnormalities [PDF]
Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2021 Background Dispersion and gradients in repolarization have been associated with life‐threatening arrhythmias, but are difficult to quantify precisely from surface electrocardiography.

Clinical Cardiology, 1999 AbstractEarly repolarization (ER) is an enigma. The purpose of this review is to reemphasize the overall electrocardiographic (ECG) pattern of this normal ST variant which continues to challenge the clinician because of its similarity to the current of injury potential to myocardium or an acute pericarditis.

Mechanisms of drowning in children: influence of cold shock response on repolarization patterns and arrhythmia burden in healthy children [PDF]
Frontiers in Sports and Active LivingIntroductionWhile drowning plays a particularly important role in children, the data on the physiology of drowning in this population are scarce. Both the cold shock response and the development of arrhythmias within the context of an autonomic conflict ...

Abnormal Cardiac Repolarization in Thyroid Diseases: Results of an Observational Study
Frontiers in Cardiovascular Medicine, 2021 Background: The relationship between thyroid function and cardiac disease is complex. Both hypothyroidism and thyrotoxicosis can predispose to ventricular arrhythmia and other major adverse cardiovascular events (MACE), so that a U-shaped relationship ...

Sarcoplasmic Reticulum Calcium Release Is Required for Arrhythmogenesis in the Mouse
Frontiers in Physiology, 2021 Dysfunctional sarcoplasmic reticulum Ca2+ handling is commonly observed in heart failure, and thought to contribute to arrhythmogenesis through several mechanisms. Some time ago we developed a cardiomyocyte-specific inducible SERCA2 knockout mouse, which

Electrocardiographic markers of myocardial conduction and repolarization in Boxer dogs [PDF]
Pesquisa Veterinária Brasileira, 2020 : Electrocardiographic markers have been used in people to classify arrhythmogenic risk. The aims of this study were to investigate electrocardiographic markers of conduction and repolarization in Boxers and non-Boxer dogs, and compare such findings ...

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2020 Background A combination of clinical and electrocardiographic risk factors is used for risk stratification in Brugada syndrome. In this study, we tested the hypothesis that the incorporation of latent variables between variables using nonnegative matrix ...
