The aim of this study was to define the electrocardiogram (ECG) changes following the moderate to severe CO intoxication in rats, and also evaluating the effect of erythropoietin (EPO) on observed cardiac disturbances. The growing literature on erythropoietin effect on cardiac ischemia led us to question its effect on cardiotoxicity due to the carbon monoxide poisoning. Wistar rats were exposed...

BACKGROUND Electrocardiogram (ECG) cardiovascular disease (CVD) abnormalities (ECG-CVD) are predictive of subsequent CVD events in the general population. Systemic lupus erythematosus (SLE) patients are vulnerable to CVD. We aimed to determine the prevalence of ECG-CVD in SLE patients and to examine the risk factors associated with ECG-CVD. METHODS A 12-lead resting supine ECG was performed o...

Background: In addition to heart disease, ECG also changes in non-heart disease, which due to its similarity, can lead to misdiagnosis of heart disease in patients. ECG changes in brain lesions such as ischemic and hemorrhagic strokes, brain traumas, etc. and have been studied in many articles, but the effects of brain midline shift on ECG changes have not been studied. In this study, we want t...

In this study, a mathematical model is developed based on algebraic equations which is capable of generating artificially normal events of electrocardiogram (ECG) signals such as P-wave, QRS complex, and T-wave. This model can also be implemented for the simulation of abnormal phenomena of electrocardiographic signals such as ST-segment episodes (i.e. depression, elevation, and sloped ascending...

Background: Simultaneous electrocardiographic (ECG) changes are seen in hemorrhagic brain events even in the absence of associated myocardial infarction (MI). This study was designed to assess the role of ECG changes to predict true MI in patients with hemorrhagic brain trauma. Methods: Data of 153 patients with traumatic brain injury and concomitant ECG changes were recorded. Enzyme study w...

Background: Benzodiazepine (BZD) toxicity alone or with other drugs is common in poisoning emergency departments of Iran. The aim of this study was to evaluate the cardiovascular findings in patients with benzodiazepine poisoning upon admission to the emergency department. Methods: In a prospective study which was followed by retrospective analysis, 267 patients poisoned with BZD were evalu...
