Revista Portuguesa de Cardiologia, 2018 Sudden cardiac death is a major public health challenge, which can be caused by genetic or acquired structural or electrophysiological abnormalities. These abnormalities include hereditary channelopathies: long QT, short QT and Brugada syndromes.

The Journal of Physiology, EarlyView.Abstact figure legend A panoramic 3D optical mapping system was developed, enabling imaging of action potential waves across the entire strongly deforming ventricular surface of beating isolated hearts. The system comprises 12 high‐speed cameras and a soccerball‐shaped imaging chamber with 48 light‐emitting diodes (LEDs).

Erg currents support electrical bursting in murine anterior pituitary corticotrophs
The Journal of Physiology, EarlyView.Abstract figure legend Anterior pituitary corticotrophs are a central component of the hypothalamic‐pituitary‐adrenal (HPA) axis that controls the release of glucocorticoids from the adrenal gland in response to stress. The hypothalamic secretagogue corticotrophin releasing hormone (CRH) promotes electrical bursting of mouse anterior pituitary ...

Indian Pacing and Electrophysiology Journal, 2002 The Long QT syndrome (LQTS) can be inherited or acquired and is of particular interest and concern at present. Patients with LQTS are predisposed to the ventricular tachyarrhythmia torsade de pointes (TdP) which causes syncope and sudden death. Inherited

The Journal of Physiology, EarlyView.Abstract figure legend A mechanistic framework linking sex‐dependent dynamical instability to proarrhythmic risk. Sex‐specific human ventricular models show that upstream modulators, including biological sex, hormones, drugs and heart disease, promote steeper APD restitution in female than male and enhance dynamical instability.

Digital genetic counseling services for cascade cardiogenetic testing
Journal of Genetic Counseling, Volume 35, Issue 3, June 2026.Abstract Digital interventions are potentially promising to improve accessibility and efficiency of genetic counseling services. However, current literature on user perspectives toward digital tools for cascade testing is limited. Therefore, this focus‐group study aimed to gain insights into the attitude and perspectives of probands, at‐risk relatives (

Genotype-Phenotype Relationships in Long QT Syndrome : Role of Mental Stress, Adrenergic Activity and a Common KCNH2 Polymorphism [PDF]
, 2006 Long QT syndrome is a congenital or acquired arrhythmic disorder which manifests as a prolonged QT-interval on the electrocardiogram and as a tendency to develop ventricular arrhythmias which can lead to sudden death.

Psychiatry and Clinical Neurosciences Reports, Volume 5, Issue 2, June 2026.This graphical summary illustrates the efficacy and safety of brexpiprazole (2–4 mg) in patients with schizophrenia. The meta‐analysis demonstrates significant improvement in clinical outcomes, with reductions in Positive and Negative Syndrome Scale (PANSS) and Clinical Global Impression ‐ Severity scale (CGI‐S) scores, indicating better symptom ...
