Electrophysiological Basis for Early Repolarization Syndrome

Frontiers in Cardiovascular Medicine, 2018
During last centuries, Early Repolarization pattern has been interpreted as an ECG manifestation not linked to serious cardiovascular events. This view has been challenged on the basis of sporadic clinical observations that linked the J-wave with ...

Seasonal changes of electrophysiological heterogeneities in the rainbow trout ventricular myocardium

Current Research in Physiology, 2022
Introduction: Thermal adaptation in fish is accompanied by morphological and electrophysiological changes in the myocardium. Little is known regarding seasonal changes of spatiotemporal organization of ventricular excitation and repolarization processes.

QT interval derived measurements in patients with cardiac syndrome X compared to coronary artery disease

Frontiers in Physiology, 2016
Previous studies assessing effect of ischemia on ventricular repolarization are mostly directed towards patients with coronary artery disease (CAD); however, similar reports on cardiac syndrome X (CSX) are scarce. Whether microvascular dysfunction of CSX

The role of cardiac acoustic biomarkers in monitoring patients with heart failure: A systematic literature review

ESC Heart Failure, Volume 12, Issue 2, Page 980-997, April 2025.
Abstract Heart failure (HF) creates a considerable clinical, humanistic and economic burden on patients and caregivers as well as on healthcare systems. To attenuate the significant burden of HF, there is a need for enhanced management of patients with HF.

In silico analysis of ventricular action potential with a current–voltage‐time representation: Thresholds, membrane resistance, repolarization reserve

Physiological Reports
The waveform of ventricular action potential (AP) is a key determinant of the cardiac cycle, a marker of beating pathophysiology, and a target for anti‐arrhythmic drug design.
