Aim: To evaluate the prevalence and longitudinal changes of prolonged QTc in DM patients admitted to our community hospital, and to determine, if any, its correlation with changes of left ventricular ejection fraction (LVEF). Methods: A retrospective chart review of patients with Type 1 (T1DM) and Type 2 (T2DM) with at least two admissions during a four-year period was performed to identify QTc...

Convulsion is one of the most common problems in children and hypocalcemia is one the most frequent etiological items in children's convulsion. Corrected QT (QTc) in EKG is prolonged in hypocalcemia, so it can be a useful tool for evaluation of serum ionized calcium. In three groups (first seizure, multiple seizures, without seizure or control ) every 25 cases, QTc, serum ionized ca, total ca, ...

We assessed the applicability of the Glasgow Coma Scale (GCS) and the QT interval (QTc) to predicting outcomes in patients with organophosphate (OP) poisoning. In the hospital setting, QTc and GCS were monitored in each patient at admission. Patients with respiratory failure were compared to patients without these complications, and mortality was compared between groups. We found that the group...

A 12-year-old girl presented with an acute confusional state and a 2-year history of weight loss, anxiety, agitation and recurrent fever. Thyroid function tests confirmed severe hyperthyroidism, and a diagnosis of thyroid storm was made (Burch and Wartofsky score=75). ECG showed a prolonged QTc interval of 506 ms. Acute treatment for thyroid storm consisted of Lugol's iodine, prednisolone, carb...

BACKGROUND: Cirrhotic Cardiomyopathy is a relatively ill-characterized condition, which is often under-diagnosed due to absence of defined diagnostic criteria. ECG showing corrected QT Interval prolongation is the most suitable available option for diagnosis of this condition. OBJECTIVE: To determine the frequency of corrected QT interval prolongation in patients with liver cirrhosis. METHODOLO...

OBJECTIVE To compare QTc duration and Heart Rate (HR) in patients with cirrhosis with non-cirrhotic controls. DESIGN Cross-sectional analytical study. PLACE AND DURATION OF STUDY Civil Hospital and Lyari General Hospital, Karachi, from March 2004 to February 2006. PATIENTS AND METHODS Confirmed patients of cirrhosis were selected and allocated to Group-I. An equal number of non-cirrhotic ...

Objectives: To test the hypothesis that the QTc of any lead of the ECG predicts death after stroke, and to determine which lead of the ECG carries the greatest risk of cardiac death when its QTc is measured. Design: Standard 12 lead ECGs were analysed by one observer who was blind to patient outcome. Setting: A major teaching hospital in Scotland. Patients: 404 stroke survivors were studied at ...

INTRODUCTION The electrocardiographic parameters QRS duration, QRS-T angle and QTc can predict mortality in patients with cardiovascular disease. The prgnostic value of these parameters in hospitalized patients with syncope needs investigation. MATERIAL AND METHODS We retrospectively studied 590 consecutive patients hospitalized with syncope. After excluding patients with baseline abnormal rh...

background : identifying the sources of variation in qtc measurements is important for preventing arrhythmias during and after hemodialysis. the present study was designed to determine the correlation between the type of hemodialysis buffer and the changes in qtc interval in patients on chronic hemodialysis.   methods: fifty-nine patients on chronic hemodialysis who referred in winter 2007 to h...

STUDY OBJECTIVE There have been 15 published cases of probable pentamidine-induced torsade de pointes (TdP). A prospective analysis of this complication of therapy is valuable considering the high frequency of Pneumocystis carinii pneumonia in the AIDS population, and the role of pentamidine in its therapy. DESIGN Open, nonrandomized, prospective study of HIV-infected patients receiving intra...
