QT-interval prolongation in right precordial leads: an additional electrocardiographic hallmark of Brugada syndrome.
OBJECTIVES The aim of this study was to evaluate whether the occurrence of the Brugada Syndrome typical electrocardiogram (ECG) pattern (i.e., right bundle branch block, coved-type ST-segment elevation, and T-wave inversion in the right precordial leads) is characterized by a concomitant lengthening of QT intervals in the right precordial leads. BACKGROUND It has been suggested that the typic...
متن کامل"QT clock" to improve detection of QT prolongation in long QT syndrome patients.
BACKGROUND The QT interval is a risk marker for cardiac events such as torsades de pointes. However, QT measurements obtained from a 12-lead ECG during clinic hours may not capture the full extent of a patient's daily QT range. OBJECTIVE The purpose of this study was to evaluate the utility of 24-hour Holter ECG recording in patients with long QT syndrome (LQTS) to identify dynamic changes in...
متن کاملGenetic analysis of Brugada syndrome and congenital long-QT syndrome type 3 in the Chinese
BACKGROUND Brugada syndrome and congenital long-QT syndrome (LQTS) type 3 (LQT3) are 2 inherited conditions of abnormal cardiac excitability characterized clinically by an increased risk of ventricular tachyarrhythmias. SCN5A gene that encodes the cardiac sodium channel α subunit is responsible for the 2 diseases, and more work is needed to improve correlations between SCN5A genotypes and assoc...
متن کاملRelation between bradycardia dependent long QT syndrome and QT prolongation by disopyramide in humans.
BACKGROUND Recent molecular biological investigations have identified abnormal genes in familial forms of long QT syndrome, but in bradycardia dependent acquired long QT syndrome, no such genetic abnormality has yet been identified. OBJECTIVE To investigate the relation between the responses of QT interval to pacing change and to disopyramide. METHODS This study included 13 patients with br...
متن کاملLong QT syndrome type 8: novel CACNA1C mutations causing QT prolongation and variant phenotypes.
AIMS CACNA1C mutations have been reported to cause LQTS type 8 (LQT8; Timothy syndrome), which exhibits severe phenotypes, although the frequency of patients with LQT8 exhibiting only QT prolongation is unknown. This study aimed to elucidate the frequency of CACNA1C mutations in patients with long QT syndrome (LQTS), except those with Timothy syndrome and investigate phenotypic variants. METH...
