Table-V: Results of multivariable analysis of independent predictors of QTc dispersion
QT and QTc dispersion
are accurate predictors of cardiac death in newly diagnosed non-insulin-dependent diabetics: cohort study.
Groups Study group Control group (n = 40) (n = 40) [beta] blocker Not using 3 (7.5) 3 (7.5) Using 37 (92.5) 37 (92.5) Renin-angiotensin system blocker Not using 2 (5) 2 (5) Using 38 (95) 38 (95) Aldosterone antagonist Not using 9 (22.5) 9 (22.5) Using 31 (77.5) 31 (77.5) Class III antiarrhythmic agents Not using 25 (62.5) 30 (75) Using 15 (37.5) 10 (25) Diuretics Not using 5 (12.5) 3 (7.5) Using 35 (87.5) 37 (92.5) p value [beta] blocker Not using 1.0 Using Renin-angiotensin system blocker Not using 1.0 Using Aldosterone antagonist Not using 1.0 Using Class III antiarrhythmic agents Not using 0.23 Using Diuretics Not using 0.71 Using Table 3: The chances of frequency of PVC, Tp-e, QTc, QTc dispersion
, and Tp-e-QTc ratio during the follow-up period in both groups.
Results: The prevalence of prolonged QTc duration was 21%, no patients have prolonged QTc dispersion
(> 80 ms).
Effect of blood gas derangement on QTc dispersion
in severe chronic obstructive pulmonary disease: evidence of an electropathy?
Conclusion: In our study we found no meaningful difference in QTc dispersion
in individuals who take bath.
Reduction of QTc dispersion
by the angiotensin II receptor blocker valsartan may be related to its anti-oxidative stress effect in patients with essential hypertension.
Effect of weight loss on QTc dispersion
in obese subjects.
Results: QT and QTc dispersion
were higher (p=0.007 and p=0.006, respectively) and PR interval was longer (p=0.009) in the patients with Eisenmenger syndrome, than those in the control group.
In all patients and control subjects, QT intervals were measured on electrocardiogram, and QTc intervals and QTc dispersion
Objective: Increased QTc dispersion
is a predictor for ventricular arrhythmias.
In a study, newly published in this issue of the Anatolian Journal of Cardiology (3), the authors investigated the changes in QTc and QTc dispersion
in obese subjects after weight loss program with diet and medical treatment.
