Since no patient had QTc dispersion above 80 ms we looked into the correlation between the QTc dispersion and glycemic variability.
In conclusion, the result of this present study suggests that increased glycemic variability associated with prolonged QTc duration and QTc dispersion, which means ventricular depolarization and repolarization are affected by glycemic variability in type 2 diabetic patients.
QTc dispersion is a non-invasive method in determining the patients with high risk related with ventricular arrhythmia and sudden death (9).
The risk of bath causing sudden death due to hot water, high medium temperature and humidity was studied by QTc dispersion, which is the non-invasive electrophysiological indicator of the ventricular arrhythmias.
In our study, we determined no meaningful difference in QTc dispersion in individuals who take bath.
To assess the observer reliability of QTc dispersion measurements, fifteen ECG records were randomly chosen for re-measurement of the QT intervals two months after the initial measurements.
Linear regression analysis was used to determine the relationship of QTc dispersion with the markers of iron levels in the HD group.
Although the mean QT interval was not significantly different between HD patients and control subjects, HD patients had a significantly longer QTc dispersion (62 [+ or -] 23 ms vs.
Therefore, the aim of this study was to investigate whether the decrease of QTc dispersion takes place after weight loss with diet and medical treatment.
The decrease in level of QTc dispersion was more prominent in Group 2 than in Group 1 after weight loss program, though it was not statistically significant (19[+ or -]23 ms vs 3[+ or -]26 ms, p>0.
The main findings of this study are that (1) substantial weight loss in obese subjects is associated significantly with the decrease in QTc dispersion and (2) decrease in value of QTc dispersion is significantly correlated with the amount of weight loss.
