Sudden cardiac death increases during winter months in both men and women. The heart rate–corrected QT (QTc) interval exhibits circadian variation. However, little is known about QTc interval variation with month of year. We sought to determine whether the QTc interval varies with month of year...
QT interval is the time from the start of the Q wave to the end of the T wave, time taken for ventricular depolarisation and repolarisation

The normal QT interval depends on age, gender, and other physiological conditions, but a QT interval ≥ 470–480 ms, in men and women respectively, is sufficient to suspect LQTS3(Fig.1). Whereas aLQTS may be due to drugs, electrolyte abnormalities, eating disorders, coronary artery disease...

with heart rates in the 60–90 beats/min range, most formu- lae provide almost equivalent results for the diagnosis of QT prolongation. Even if the rate dependence of the QT interval is probably best described by an exponential relation, in the normal heart rate range the QT–RRrelation is...
QT interval and QTd were measured using automated analysis in the remaining 83 patients (46 men, age 40 ± 14 years, range 16 to 76). QT interval (406 ± 38 ms), QTc interval (432 ± 27 ms), and QTd (43 ± 25 ms) were significantly greater in patients with HC than in normal ...
These exclusions were chosen to reduce the risk of confounding in our analyses of ECG parameters, where the bulk of the power comes from normal variation of QT, JT, and QRS. This will have reduced the total sample size available, however the genetic contribution to ECG interval variation in ...
