Acquired Long QT Syndrome and Electrophysiology of Torsade de Pointes.

Congenital long QT syndrome (LQTS) has been the most investigated cardiac ion channelopathy. Although congenital LQTS remains the domain of cardiologists, cardiac electrophysiologists and specialised centres, the much more frequently acquired LQTS is the domain of physicians and other members of healthcare teams required to make therapeutic decisions. This paper reviews the electrophysiological mechanisms of acquired LQTS, its ECG characteristics, clinical presentation, and management.

A role for complement in glaucoma?

Chronic open angle glaucoma is a degenerative optic neuropathy that can lead to blindness. We have shown that one of the major genes with altered expression in the glaucomatous retina is complement component C1q in both animal models of the disease as well as in humans. These observations together with evidence of upregulation of other complement components within the retina suggest a role for complement in the pathogenesis of this disease.
