Brugada syndrome: report of the second consensus conference: endorsed by the Heart Rhythm Society and the European Heart Rhythm Association.
The present report elaborates further on the diagnostic criteria and examines risk stratification schemes and device and pharmacological approaches to therapy on the basis of the available clinical and basic science data. Expand
Contemporary definitions and classification of the cardiomyopathies: an American Heart Association Scientific Statement from the Council on Clinical Cardiology, Heart Failure and Transplantation…
The present classification scheme recognizes the rapid evolution of molecular genetics in cardiology, as well as the introduction of several recently described diseases, and is unique in that it incorporates ion channelopathies as a primary cardiomyopathy. Expand
Genetic basis and molecular mechanism for idiopathic ventricular fibrillation
It is shown that sodium channels with the missense mutation recover from inactivation more rapidly than normal and that the frameshift mutation causes the sodium channel to be non-functional. Expand
Cellular basis for the Brugada syndrome and other mechanisms of arrhythmogenesis associated with ST-segment elevation.
Depression or loss of the action potential dome in RV epicardium creates a transmural voltage gradient that may be responsible for the ST-segment elevation observed in the Brugada syndrome and other syndromes exhibiting similar ECG manifestations. Expand
Sudden Death Associated With Short-QT Syndrome Linked to Mutations in HERG
The genetic basis for a new clinical entity characterized by sudden death and short-QT intervals in the ECG is described and a novel genetic and biophysical mechanism responsible for sudden death in infants, children, and young adults caused by mutations in KCNH2 is demonstrated. Expand
Loss-of-Function Mutations in the Cardiac Calcium Channel Underlie a New Clinical Entity Characterized by ST-Segment Elevation, Short QT Intervals, and Sudden Cardiac Death
This is the first report of loss-of-function mutations in genes encoding the cardiac L-type calcium channel to be associated with a familial sudden cardiac death syndrome in which a Brugada syndrome phenotype is combined with shorter-than-normal QT intervals. Expand
J-Wave syndromes expert consensus conference report: Emerging concepts and gaps in knowledge.

Characteristics of the delayed rectifier current (IKr and IKs) in canine ventricular epicardial, midmyocardial, and endocardial myocytes. A weaker IKs contributes to the longer action potential of…
The results suggest that the distinctive phase-3 repolarization features of M cells are due in part to a lesser contribution of IKs and that this distinction may also explain why M Cells are the main targets for agents that prolong APD in ventricular myocardium. Expand
Ionic bases for electrophysiological distinctions among epicardial, midmyocardial, and endocardial myocytes from the free wall of the canine left ventricle.
The data suggest that prominent heterogeneity exists in the electrophysiology of cells spanning the canine ventricular wall and that differences in the intensity of the transient outward current contribute importantly, but not exclusively, to this heterogeneity. Expand
An international compendium of mutations in the SCN5A-encoded cardiac sodium channel in patients referred for Brugada syndrome genetic testing.
Overall, 21% of BrS probands have mutations in SCN5A compared to the 2% to 5% background rate of rare variants reported in healthy control subjects, which may help further distinguish pathogenic mutations from similarly rare but otherwise innocuous ones found in cases. Expand
