Methods of Assessment and Clinical Relevance of QT Dynamics [PDF]
, 2005 The dependence on heart rate of the QT interval has been investigated for many years and several mathematical formulae have been proposed to describe the QT interval/heart rate (or QT interval/RR interval) relationship. While the most popular is Bazett’s

Potential health benefits of cold‐water immersion: the central role of PGC‐1α
The Journal of Physiology, EarlyView.Abstract figure legend Cold‐water immersion (CWI) elicits autonomic, somato‐motoric (shivering thermogenesis), endocrine and metabolic, sensory transduction, and local biophysical effects that may converge on the transcriptional co‐activator PGC‐1α (centre).

Ventricular Tachycardia in the Absence of Structural Heart Disease [PDF]
In up to 10% of patients who present with ventricular tachycardia (VT), obvious structural heart disease is not identified. In such patients, causes of ventricular arrhythmia include right ventricular outflow tract (RVOT) VT, extrasystoles, idiopathic ...

The Journal of Physiology, EarlyView.Abstract figure legend Mitochondrial SK channel enhancement reduces cardiac arrhythmia trigger. Spontaneous sarcoplasmic reticulum (SR) Ca2+ release via hyperactive RyR2s underlies an increased arrhythmia trigger, promoting early and delayed afterdepolarizations during stress. Hyperactive RyR2s causes rise in cytosolic [Ca2+] during diastole. Clearance

Caenorhabditis elegans as an in vivo model system for human inherited primary arrhythmia syndromes
The Journal of Physiology, EarlyView.Abstract figure legend Most genes involved in inherited primary arrhythmia syndromes (IPAS) are conserved in Caenorhabditis elegans, where genetic manipulation enables functional characterization of variants, identification of regulatory proteins, and in vivo drug testing.

A superfamily of small potassium channel subunits: form and function of the MinK-related peptides (MiRPs). [PDF]
, 1998 MinK and MinK-related peptide I (MiRPI) are integral membrane peptides with a single transmembrane span. These peptides are active only when co-assembled with pore-forming K+ channel subunits and yet their role in normal ion channel behaviour is ...

The Journal of Physiology, EarlyView.Abstract figure legend Schematic diagram illustrating the proposed pathway in which regulatory defects might occur in sympathetic neurons derived from hiPSC in catecholaminergic polymorphic ventricular tachycardia (CPVT). Specifically, enhanced calcium transients appeared to derive from three sources: enhanced membrane excitability (due to loss of ...
