BACKGROUND AND PURPOSE Stroke is the third leading cause of death in most Western countries. Cardioembolism might be responsible for 15% to 20% of ischemic strokes. Although atrial fibrillation can be diagnosed by electrocardiography, the remaining causes of cardioembolic stroke are diagnosed by echocardiography. Recent recommendations on the management of acute ischemic stroke fail to consider...

Background: Chronotropic incompetence has prognostic value of all-cause and cardiovascular mortality in both patients with asymptomatic and symptomatic ischemic heart disease (IHD), regardless of traditional risk factors. The aim of this study was to investigate the relationship between chronotropic response during exercise test and the development of ventricular arrhythmias. Methods: 153 pati...

Background: We designed a cross-sectional study to determine electrocardiographic disorders in Down syndrome patients with congenitally normal hearts in a bid to predict fatal cardiac arrhythmia in the future. Materials and Methods: We investigated 60 children with DS without congenital abnormal hearts. Sixty healthy juveniles were also included in the study as a control group. Physical examina...

BACKGROUND Plasma cardiac troponins (cTn) are frequently elevated in acute pulmonary embolism (APE). ST-segment abnormalities on electrocardiography are also commonly observed in APE patients. However, it has not been defined which ventricle is a potential source of cTn release. We assessed the potential relationship between electrocardiographic signs of myocardial ischemia, systolic dysfunctio...

a double left anterior descending (lad) coronary artery emerging from the left and right coronary arteries is classified among rare coronary anomalies. we herein report a 73-year-old man presenting with acute coronary syndrome (posterolateral myocardial infarction). he was admitted with typical chest pain, and due to his progressive ischemic changes on electrocardiography (ecg) and elevated car...

background: n-terminal pro-brain natriuretic peptide (nt-probnp) is a sensitive biomarker for the detection of asymptomatic left ventricular (lv) dysfunction. since β-thalassemia major patients suffer from early diastolic dysfunction due to iron deposition of chronic blood transfusion, we tried to evaluate the correlation between the serum nt-probnp level and the severity of lv diastolic dysfun...
