Association between maximal oxygen uptake and the heart rate corrected-QT interval in postmenopausal overweight women.
BACKGROUND Increased aerobic capacity can reduce the incidence of cardiovascular disease and the mortality rate. On the other hand, a prolonged heart rate corrected-QT (QTc) interval is associated with an increased risk of arrhythmias, cardiac sudden death and coronary artery disease. AIMS The association of the aerobic capacity and coronary risk factors with QTc interval was investigated in ...
متن کاملInfluence of Dietary Sodium and Potassium Intake on the Heart Rate Corrected-QT Interval in Elderly Subjects.
It is well known that imbalances in the dietary electrolytes are associated with a significantly higher incidence of cardiovascular disease (CVD). On the other hand, a prolonged heart rate corrected-QT (QTc) interval is associated with an increased risk of cardiac autonomic nervous system dysfunction, the incidence of CVD and sudden cardiac death. This study was designed to clarify the associat...
متن کاملEffects of cisapride on corrected QT interval, heart rate, and rhythm in infants undergoing polysomnography.
OBJECTIVE To evaluate the effects of cisapride, a prokinetic gastrointestinal drug, on the electrocardiographic QT interval, heart rate, and rhythm in infants during routine 8-hour polysomnography. Reported electrocardiogram (ECG) and rhythm disturbances in a small number of patients with the use of cisapride provided the impetus for this prospective study. STUDY DESIGN Two hundred fifty-two ...
متن کاملAtrial and Ventricular Electrocardiographic Dromotropic Disturbances in Down Syndrome Patients with Structurally Normal Heart: A Cross-Sectional Study
Background: We designed a cross-sectional study to determine electrocardiographic disorders in Down syndrome patients with congenitally normal hearts in a bid to predict fatal cardiac arrhythmia in the future. Materials and Methods: We investigated 60 children with DS without congenital abnormal hearts. Sixty healthy juveniles were also included in the study as a control group. Physical examina...
متن کاملQT Interval: Correction for Heart Rate
There are several empirically based proposals in the literature for adjusting QT intervals for heart rate. Two widely used correction formulas are Bazett’s and Fridericia’s. This study examines the general formulation of heart rate correction of QT intervals, and several of the existing adjustments are used with this approach. Simple correction formulas for both populations and individuals have...
