Connexin40 imparts conduction heterogeneity to atrial tissue.
Impulse propagation in cardiac tissue is a complex process in which intercellular coupling through gap junction channels is a critical component. Connexin40 (Cx40) is an abundant gap junction protein that is expressed in atrial myocytes. Alterations in the expression of Cx40 have been implicated in atrial arrhythmogenesis. The purpose of the current study was to assess the role of Cx40 in atria...
متن کاملPathophysiological heterogeneity of conduction blocks in multifocal motor neuropathy.
The pathophysiological mechanisms responsible for conduction block in multifocal motor neuropathy (MMN) are still unclear. To clarify the physiological abnormalities at the site of the block, we tested the effects induced by polarizing direct currents on motor conduction along forearm nerves in 25 normal nerves (13 subjects), and at the site of conduction block in six nerves (five patients) wit...
متن کاملNon-invasive electrocardiographic methods for assessment of atrial conduction heterogeneity in ankylosing spondylitis.
We would like to thank the authors for the letter entitled “Supraventricular arrhythmia risk in ankylosing spondylitis patients” regarding with our manuscript published in your distinguished journal1. In current study, we used P wave duration and P-wave dispersion (Pd) for evaluation of supraventricular arrhythmia risk in ankylosing spondylitis. P wave duration is known to have significant corr...
متن کاملEnhanced heterogeneity of myocardial conduction and severe cardiac electrical instability in annexin A7-deficient mice.
OBJECTIVES Annexin A7 is involved in cardiomyocyte membrane organization and Ca(2+)-dependent signalling processes. We investigated the impact of annexin A7 on cardiac electrophysiological properties using an annexin A7-deficient mouse strain (annexin A7(-/-)). METHODS Nineteen adult annexin A7(-/-) and 14 wild-type mice were examined electrophysiologically in vivo by transvenous catheterizat...
متن کاملElectrical heterogeneity and conduction block in reoxygenated guinea pig papillary muscles.
To investigate the changes in electrical activity after reoxygenation, guinea pig papillary muscles were reoxygenated with 5 mM glucose solution after various durations (30-120 min) of substrate-free hypoxia. Action potential duration recovered to the control level on reoxygenation following 30-120 min hypoxia. The recovery of developed tension or resting tension was incomplete after reoxygenat...
