introduction: previous studies have raised the probably of cardiac manifestation in tramadol poisoning. however, conclusive information on electrocardiographic (ecg) abnormalities of tramadol overdose remains to be explained. therefore, the present study aimed to evaluate the epidemiology of ecg abnormalities in tramadol poisoned patients. methods: in a prospective cross-sectional study, all pa...
BACKGROUND Blood donor screening leads to large numbers of new diagnoses of Trypanosoma cruzi infection, with most donors in the asymptomatic chronic indeterminate form. Information on electrocardiogram (ECG) findings in infected blood donors is lacking and may help in counseling and recognizing those with more severe disease. OBJECTIVES To assess the frequency of ECG abnormalities in T.cruzi...
The importance of electrocardiographic (ECG) abnormalities at baseline examination for subsequent risk of stroke was analyzed in a 12-year follow-up of 7,560 men in the Honolulu Heart Program, aged 45-68 years, who were free of coronary heart disease and stroke at baseline. Age-adjusted univariate analysis showed that men with major ST depression, left ventricular strain, left ventricular hyper...
PURPOSE To determine the prevalence of heart rate changes and ECG abnormalities during epileptic seizures and to determine the timing of heart rate changes compared to the first electrographic and clinical signs. To assess the risk factors for the occurrence of ECG abnormalities. METHODS We analyzed retrospectively 281 seizures in 81 patients with intractable epilepsy who had prolonged video-...
BACKGROUND Electrocardiogram (ECG) abnormalities following aneurysmal subarachnoid hemorrhage (SAH) have been well documented. Evidence suggests that ECG changes and cardiac dysfunction worsen outcome. Determining which patients are at most risk is unclear but important to ascertain. METHODS We prospectively studied clinical markers, cardiac abnormalities, and clinical outcomes in 20 patients...
BACKGROUND Information is limited about the independent prognostic value of repolarization abnormalities in women. METHODS AND RESULTS We evaluated hazard ratios for ECG variables for combined fatal and nonfatal coronary heart disease (CHD) events and for CHD mortality using Cox regression in 38,283 Women's Health Initiative (WHI) participants during up to 9.2 years of follow-up. All risk mod...
BACKGROUND Electrocardiographic (ECG) abnormalities are frequent in patients with intracranial insult. In this study, we evaluated the factors predisposing to the repolarization abnormalities, i.e., prolonged corrected QT (QTc) interval, ischemic-like ECG changes and morphologic end-repolarization abnormalities, and examined the prognostic value of these abnormalities in patients with subarachn...
The importance of major and minor ECG abnormalities at baseline for subsequent risk of death from coronary heart disease, cardiovascular diseases and all causes was analyzed for middle-aged white men from the Chicago Peoples Gas Company, Chicago Western Electric Company and Chicago Heart Association Detection Project in Industry studies. Univariate analysis showed that in all three studies, men...
