background: acute respiratory distress (ard) is a critical respiratory failure due to lung injury of neonates leading to the clinical appearance of poor lung compliance. the aimed of the study was to evaluate the diagnostic values in differentiating respiratory from heart diseases with using of n-terminal pro brain natriuretic peptide (nt-pro bnp) and atrial natriuretic peptide(anp) in neonates...

the overall rate of atrial pacing lead dislodgement is estimated to be about 3%. these leads are generally repositioned via a second operation through opening the pacemaker pocket. some operators have introduced percutaneous techniques using snare system or deflectable catheters for this purpose. in this article we present our experience with five cases of percutaneous lead repositioning. three...

Introduction: Recent evidence has indicated that statins can reduce the incidence of both supraventricular and ventricular arrhythmias with various mechanisms. The primary goal of the present study was to determine direct protective role of simvastatin in modifying concealed conduction and the zone of concealment in a simulated model of atrial fibrillation (AF) in an isolated atrioventricula...

Introduction: It was shown in a previous study, that MCPIP, a cilostamide derivative, increased atrial contraction force without changing contraction rate. To improve this property, two new derivatives of cilostamide were synthesized and their effects on PDE3 activity and isolated rat atria contraction were investigated. Methods: The inhibitory effect of each compound on PDE3 enzyme was dete...

Electrocardiography (ECG) may be used to recognize cardiac disorders. Levels of milk production may change the serum electrolytes which its imbalance has a role in cardiac arrhythmia. Fifty high yielding and fifty low yielding Holstein dairy cows were used in this study. Electrocardiography was recorded by base-apex lead and blood samples were collected from jugular vein for measurement of seru...

diabetic mellitus (dm) is a major risk factor of morbidity, mortality and economic cost to society. diabetic patients are at risk of having microvascular or macrovascular disorders of diabetes. postoperative anemia have wide spectrum of some early complications that require more care in hospitalization stays. therefore, this study was designed to evaluate effect of preoperative anemia on short-...
