QT prolongationQT/QTcrac-sotalolAimTo study the differences in QTc interval on ECG in response to a single oral dose of rac-sotalol in men and women.MethodsContinuous 12-lead ECGs were recorded in 28 men and 11 women on a separate baseline day and following a single oral dose of 160 ...
QT c prolongation occurred in all procedures in all donors. Maximum recorded values were significantly higher in women than in men (450.8 ± 20.8 vs. 424.8 ± 14.3 ms 1/2 ; p = 0.0025). All QT c values returned to baseline by 15 minutes after the procedure. Changes in blood pressure ...

Heart rate-corrected QT interval prolongation predicts risk of coronary heart disease in black and white middle-aged men and women: the ARIC study. ObjectivesWe aimed to study the predictive value of heart rate-corrected QT interval (QTc) for incident coronary heart disease (CHD) and cardiovascula...
A total of 629 patients (mean [SD] age at time of death, 61.4 [15.7] years; 439 men [69.8%] and 190 women [30.2%]) included 525 WHO-defined (presumed) SCDs and 104 trauma controls for analysis. Compared with trauma controls, individuals with presumed SCDs were older (mean [SD] ...
aWith ischaemia there is less shortening of the QT interval or even a prolongation during exercise . Therefore, normal values for QT interval-heart rate during ramp exercise tests on bicycles were required. Since generally, interval at rest is longer in women than in men both sexes were include...

that the heart rate was much higher in women compared with men, and increased heart rate may be one of the signs underlying increased sympathetic tone, which is linked to QT prolongation in this population with a mean age of about 65 years. An augmented pulsatile load in elderly women may ...
