Objectives: Evaluate electrocardiographic and echocardiographic data in asymptomatic patients affected by Systemic Sclerosis (SSc) compared to healthy subjects, to assess their correlations in a case-control study. Methods: 71 female patients affected by SSc (Group A) were compared to 60 healthy female subjects (Group B). Both patients and controls were evaluated by electrocardiogram and trans-...

BACKGROUND Left ventricular hypertrophy (LVH) is very common in hemodialysis patients and an independent risk factor for mortality in this population. The myocardial remodeling underlying the LVH can affect ventricular repolarization causing abnormalities in QT interval. OBJECTIVE to evaluate the reproducibility and reliability of measurements of corrected QT interval (QTc) and its dispersion...

Cardiovascular complication should be evaluated in patient with T1DM. Ventricular instability (QT abnormalities) in Type 1 Diabetes Melitus (T1DM) is a risk factor for mortality. Prolongation of corrected QT interval (QTc) is accurate and the most sensitive test for the autonomic neuropathy whether QT interval dispersion (QTd) in arrhythmia is a predictor for mortality. This study is to evaluat...

We report that sevoflurane not only caused marked QTc interval prolongation but also increased transmural dispersion of repolarization in a patient with long QT syndrome 3 (LQT3). A 16-year-old male with LQT3 underwent a shoulder operation. He experienced no episode of syncope or cardiac arrest, but his preoperative electrocardiography (ECG) showed marked QTc interval prolongation (631 ms) and ...

OBJECTIVE To evaluate the predictive role of increased corrected QT (QTc) and QT interval dispersion (QTd) on all-cause and cardiovascular mortality in a large, unselected type 2 diabetic population. RESEARCH DESIGN AND METHODS The prospective study included 1,357 type 2 diabetic patients from the Casale Monferrato Study. At baseline, QTc intervals >0.44 s and QTd intervals >0.08 s were consi...

Hypothyroidism has various cardiovascular manifestation and exhibits electrocardiographic change. The QT dispersion on surface ECG reflects regional variations in myocardial repolarization. The effect of L-thyroxine treatment on ECG parameters, such as QT dispersion, in patients with primary hypothyroidism were investigated. This study involved 18 patients (3 men, 15 women, ages: 48+/-18 yr) wi...

BACKGROUND There has not been a longitudinal investigation of the influence of angiotensin-converting enzyme (ACE) insertion/deletion and angiotensinogen (AGT) M235T gene polymorphisms on repolarization parameters, such as QT dispersion (QTd) and the peak and the end of the T-wave interval (Tpe). METHODS AND RESULTS Electrocardiographys were recorded from 106 elderly Chinese at baseline, and ...

Objective: To evaluate repolarization defects and arrhythmogenic predisposition through ventricular markers in patients with subclinical hyperthyroidism (sHT).
 Materials Methods: Patients asymptomatic endogenous sHT healthy participants similar age demographic characteristics were included our study. Laboratory tests echocardiographic evaluations performed. Specific markers,such as QT, QT...

OBJECTIVE To assess the feasibility of 12-lead electrocardiographic (ECG) measures such as P wave dispersion (PWd), QT interval, QT dispersion (QTd), Tp-e interval, Tp-e/QT and Tp-e/QTc ratio in predicting poor outcome in patients diagnosed with sepsis in pediatric intensive care unit (PICU). METHODS Ninety-three patients diagnosed with sepsis, severe sepsis or septic shock and 103 age- and s...
