Electrophysiological characterization of pre‐adolescents born with intrauterine growth restriction: insights from clinical and computational data

The Journal of Physiology, EarlyView.
Abstract figure legend Depolarization and repolarization duration analysis was conducted in preadolescent groups with IUGR and controls using a 12‐lead ECG. Principal component analysis was applied over the 12‐lead ECGs to generate spatially transformed leads better suited for robust ECG fiducial points detection.

The influence of delayed ventricular activation on cardiac repolarization: Insights from electrocardiographic imaging

The Journal of Physiology, EarlyView.
Abstract figure legend This study examines the relationships between activation and repolarization times in epicardial reconstructed unipolar electrograms derived from ECG‐imaging in patients with normal and delayed ventricular activation. In patients with a narrow QRS‐complex, ECG‐imaging reveals significant variability in the activation ...

Repolarization adaptation to rapid change in heart rate in human models – a review

The Journal of Physiology, EarlyView.
Abstract figure legend This review focuses on non‐invasive assessment of repolarization duration and dispersion (heterogeneity) adaptation to change in heart rate (HR). HR was increased incrementally by left atrial pacing during an electrophysiology (EP) study and by a bolus injection of atropine and in a step up/down fashion by repeated right atrial ...

4D ultrasound reveals regional left atrial strain remodelling in a murine model of reversible pressure overload

The Journal of Physiology, EarlyView.
Abstract figure legend Traditional planar imaging approaches of the left atrium do not capture complex geometry. Four‐dimensional imaging allows the acquisition of 3D data + time to visualize left atrial geometry and kinematics. We designed an advanced analysis technique to investigate left atrial biomechanics in a model of pressure overload and ...
