OBJECTIVE To evaluate the relation between QT variables and disproportion of left ventricular wall hypertrophy in patients with hypertrophic cardiomyopathy. DESIGN Retrospective analysis of the results of echocardiography and electrocardiography. SETTING University hospital (tertiary referral centre). PATIENTS 70 patients with hypertrophic cardiomyopathy were divided into four groups acco...

Background: Breath holding spells (BHS) are paroxysmal events with apnea and postural tone with Electrocardiography (ECG) abnormality and epilepsy status reports. The study aimed to compare the ECG parameters’ in epilepsy and breath-holding children compared with healthy children. Materials and Methods: </st...

AIM It has previously been shown that β-blocker therapy reduces QT dynamics in heart failure patients. The aim of this study was to demonstrate this improvement with the third-generation β-blocker, nebivolol. METHODS A total of 72 heart failure patients with systolic dysfunction were included in the study. Corrected QT (QTc) and QT dispersion (QTcd) were measured manually by two independent o...

The significance of cardiac autonomic neuropathy (CAN) has not been fully appreciated and there is no unified treatment algorithm. Aim: To investigate the effects benfotiamine (BFT) on corrected QT interval (QTc), dispersion (QTd) spatial QRS-T angle in patients with type 2 diabetes mellitus (T2DM) CAN. 32 T2DM definite stage CAN were allocated to two groups: control (n = 15) received standard ...

AIMS We sought to explore the response of the corrected QT (QTc) interval duration and QT dispersion (QTD) to hemodialysis. METHODS We enrolled 50 patients with end-stage renal disease undergoing regular hemodialysis. Blood samples were drawn for measurement of serum electrolytes, and a 12-lead ECG was performed to measure the QTc interval duration and QTD, immediately before and just after d...

Heart failure continues to be a major challenge to healthcare; several resting and exercise electrocardiographic parameters have been investigated to predict the left ventricular diastolic dysfunction (LVDD). One hundred and forty patients, classified into 2 groups according to LVDD, were assessed by measurement of normal and corrected QT interval, T wave peak to T wave End and P wave dispersio...
