Acute myocardial infarction (AMI) is usually due to thrombotic occlusion of coronary arteries.Interacellular magnesium decreases after AMI. One of the drugs in treatment of AMI is parenteral magnesium sulphate that its efficacy is still ambiguous in decreasing ventricular arrhythmia and in-hospital mortality rate.We decided to investigate magnesium efficacy in in-hospit...
background and objective : sleep deprivation (sd) is caused by a host of reasons and has numerous consequences on cardiac system. in this study, we aimed to assess the preconditioning effects of acute sd on ischemia (is)-induced ventricular arrhythmias in isolated rat hearts. materials and methods : male wistar rats randomly were placed into the four groups: is-group, acute sd group, control gr...
objective: in ventricular arrhythmias, due to their free radical scavenging action, antioxidant agents are usually used in the treatment of cardiovascular disease. since stress is considered as risk factor for increased mortality by causing malignant arrhythmias, the study was designed to evaluate the cardioprotective effects of ellagic acid (ea) on cacl2-induced arrhythmias in rat stress model...
Prolonged Oral Administration of Oleuropein Might Protect Heart against Aconitine-induced Arrhythmia
In this study, it was surveyed to know whether an oral single dose of oleuropein could mimic the cardiac preconditioning in rats’ hearts or whether its prolonged oral administration could protect the heart against the aconitine-induced arrhythmia in rats. Eighty male Wistar rats were divided into two series (n = 8 in each group). In the first series, all groups (except the control (Con) group) ...
background: cirrhotic patients are at a greater risk of different kinds of arrhythmias. despite the well-known arrhythmogenic effects of halothane, developing countries continue to use halothane due to its low cost. this study was designed to investigate the pathophysiology of halothane untoward effects on heart rhythm moreover was aimed to explore the effect of halothane anesthesia on the thre...
Introduction: The present study is aimed to evaluate electrophysiological remodeling of atrioventricular (AV) node and ventricular conduction during experimental atrial fibrillation (AF) model in isolated heart of cirrhotic rats. Methods: Cirrhosis-induced electrophysiological remodeling was evaluated in 24 isolated retrogradely perfused rat hearts in 2 groups (control and cirrhotic). Cirrho...
Introduction: QT dispersion in a 12 lead ECG represents the heterogeneity of ventricular repolarization. The prolongation of QT-interval dispersion increases the risk of coronary heart disease, ventricular arrhythmia, and sudden cardiac death in patients with myocardial infarction. We aimed to investigate the prognostic value of QT-dispersion in patients with acute myocardial infarction. Meth...
acute inferior myocardial infarction (mi) frequently involves the right ventricle (rv).1-3 we assessed the prognostic impact of rv myocardial involvement in patients with inferior mi. one hundred seventy patients were admitted to the cardiac care unit of madani heart hospital (tabriz-iran) with the diagnosis of inferior mi with (group1) or without (group2) the simultaneous involvement of rv dur...
introduction a sudden loss of consciousness followed by abnormal movements can be ictal or syncopal in origin. transient response by the brain to sudden decrease of blood flow may cause sudden loss of consciousness followed by abnormal movements that mimic seizure. dysrhythmia is one of the important and critical reasons of such events that should be differentiated from seizure. case presentati...
noncompaction of the ventricular myocardium is an embryonic cardiomyopathy that is increasingly being recognized. noncompaction of lv myocardium, right ventricular myocardium, or both can occur in isolation, in congenital heart diseases, in valvular heart diseases, in neuromuscular disorders, skeletal abnormalities and in endocrinologic abnormalities. clinical manifestations of ventricular non-...
