The purpose of the present study is to assess QT-interval measurements from the EASI 12-lead electrocardiogram (ECG) as compared with the standard 12-lead ECG. The QT interval was automatically determined in simultaneously recorded standard and EASI 12-lead ECGs, using a validated wavelet-based delineator. The agreement between the 2 sets of measurements was quantified both on a lead-by-lead ba...

torsades de pointes is a rare but potentially lethal arrhythmia which mainly occurs in the setting of a prolonged qt interval. ecg is a reliable tool to detect such abnormalities, routinely taken from all patients over 40 who undergo surgery. we describe the case of a 35-year-old woman with torsades de points arrhythmia after hysterectomy surgery. most likely, our patients had long qt syndrome ...

The relation between QT interval and heart rate has been studied in a group of patients undergoing physiological exercise, in a group undergoing atrial pacing without exercise, and in a group with complete heart block undergoing exercise at a fixed ventricular rate controlled by cardiac pacing. The expected shortening in QT interval during physiological exercise is only in part the result of th...

mHE exercise electrocardiogram is a fairly well established and frequently used procedure as an adjunct in the diagnosis of symptomatic or latent coronary insufficiency. Many authors have confirmed its value.'-" The criteria for a positive test, however, still remain somewhat controversial. The value of "ischemic" type ST-segment depression is well documented, but the problem of the significanc...

INTRODUCTION Antimonial compounds are regarded as the treatment of choice for cutaneous leishmaniasis (CL). Systemic administration of these drugs has some side effects including cardio toxicity and electrocardiogram (EKG) changes. The objective of our study was to evaluate EKG changes in the patients with CL treated with systemic glucantime. MATERIALS AND METHODS One hundred and thirty-one p...

BACKGROUND Increased variability of QT interval (QTV) has been linked to arrhythmias in animal experiments and multiple clinical situations. Congenital long QT syndrome (LQTS), a pure repolarization disease, may provide important information on the relationship between delayed repolarization and QTV. METHODS AND RESULTS Twenty-four-hour Holter monitor tracings from 78 genotyped congenital LQT...

959 OBSTRUCTIVE SLEEP APNEA (OSA) IS A COMMON DISORDER OF BREATHING THAT OCCURS DURING SLEEP AND AFFECTS OVER 4% OF MEN AND 2% OF WOMEN1 and is an independent risk factor for cardiovascular disease.2 Sudden cardiac death (SCD) amongst OSA patients occurs predominantly at night, in contrast to the general population.3 A study of 400 OSA patients revealed that nearly half of them develop cardiac ...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/ bcr-2015-209942 DESCRIPTION Quadriceps tendon (QT) ruptures are uncommon injuries that predominantly affect middle-aged men. Ruptures occur as a result of direct or indirect trauma to the knee with a powerful eccentric contraction of the QT being the most frequent ca...

Background: The main manifestation of Type 1 diabetes mellitus (T1DM) is insulin insufficiency which eventually leads to body weight loss and a diversity of organ dysfunctions. On the other hand, quercetin (QT) is an antioxidant and an insulin secretagogue. We hypothesize that the amino acid mixture (AAM) preparation and/or AAM+ quercetin(QT) probably could ameliorate these adverse effects. Met...
