Short QT syndrome (SQTS) leads to an abbreviated QTc interval and predisposes patients to life-threatening arrhythmias. To date, two forms of the disease have been identified: SQT1, caused by a gain of function substitution in the HERG (I(Kr)) channel, and SQT2, caused by a gain of function substitution in the KvLQT1 (I(Ks)) channel. Here we identify a new(More)
BACKGROUND The sudden infant death syndrome (SIDS) is multifactorial in origin, but its causes remain unknown. We previously proposed that prolongation of the QT interval on the electrocardiogram, possibly resulting from a developmental abnormality in cardiac sympathetic innervation, may increase the risk of life-threatening ventricular arrhythmias and(More)
Cardiovascular diseases (CVD) are the leading cause of mortality both in men and women. In Europe, about 55% of all females' deaths are caused by CVD, especially coronary heart disease and stroke. Unfortunately, however, the risk of heart disease in women is underestimated because of the perception that women are 'protected' against ischaemic heart disease.(More)
BACKGROUND The prevalence of genetic arrhythmogenic diseases is unknown. For the long-QT syndrome (LQTS), figures ranging from 1:20 000 to 1:5000 were published, but none was based on actual data. Our objective was to define the prevalence of LQTS. METHODS AND RESULTS In 18 maternity hospitals, an ECG was performed in 44 596 infants 15 to 25 days old (43(More)
OBJECTIVE To assess the true prevalence of congenital complete heart block (CCHB) in infants of anti-Ro/SSA-positive women known to have connective tissue disease (CTD) and, secondarily, to evaluate the prevalence of other electrocardiographic abnormalities in these newborns at birth. METHODS A prospective study was conducted in 4 referral hospitals. One(More)
AIMS There are gender-related differences in the QT interval measured from standard ECG tracings. However, these observations are based on a limited number of beats recorded in resting conditions. Computerized Holter techniques enable ventricular repolarization and its relationship with cardiac cycle length to be analysed long term. Previous studies used(More)
The interest for the antifibrillatory effect of vagal stimulation has been largely limited by the fact that this concept seemed restricted to acute experiments in anesthetized animals. To explore the potentially protective role of vagal stimulation in conscious animals we developed a chronically implantable device to be placed around the cervical right(More)
A recent report of the EuroHeart project has shown that women are still underrepresented in many cardiovascular clinical trials, while important gender differences are present within most areas of heart disease. As the burden of cardiovascular disease is increasing in middle-aged women relative to men, a more profound understanding is needed of the(More)
