The effect of intermittent fasting and water restriction on myocardial ischemia/reperfusion-induced arrhythmia in rats
نویسندگان
چکیده
Results: The score of arrhythmia that was determined using the type and duration of arrhythmia did not show significant differences among groups. The arrhythmic period was significantly longer in animals subjected to 1 month of intermittent water and food restriction. The risk of ischemic zone was found to be significantly larger in the animals subjected to 1 month of normal feeding after 1 month of food and water restriction.

The effects of ATP-dependent potassium channel opener; pinacidil, and blocker; glibenclamide, on the ischemia induced arrhythmia in partial and complete ligation of coronary artery in rats
Objective(s): Electrical inhomogeneity between ischemic and non ischemic myocardium is the basis of arrhythmia which occurs following coronary artery occlusion. The leakage of potassium from the ischemic region to the non ischemic region is very effective in the generation of these arrhythmias. The aim of this study is to research the effect of ATP-dependent potassium (KATP) channel blocker (gl...

Objective(s):This study aimed to examine the hypothesis that an antiarrhythmic effect might be obtained by ischemic preconditioning of the liver, and also to characterize the potential underlying mechanisms. Materials and Methods: Male Wistar rats were anesthetized by thiopental sodium (50 mg/kg, IP) followed by IV injection of heparin (250 IU). Remote ischemic preconditioning (RIPC) was induce...

Introduction: Inhibition of renin angiotensin system represents an important approach in the management of cardiovascular diseases. The aim of this study was to explore the effects of pretreatment with non-hypotensive dose of angiotensin converting enzyme (ACE) inhibitor, ramiprilat and angiotensin type 1 (AT1) receptor blocker, losartan on myocardial infarct size and arrhythmias in a rat mo...
متن کاملAcute effect of burn trauma to small skin areas on myocardial ischemia reperfusion
Introduction: It has been reported that traumas such as transverse abdominal incision before myocardial ischemia result in a significantly decreased infarct size. This phenomenon is named remote preconditioning of trauma. Since small skin burn is one of most common traumas, the effect of this injury on ischemia-induced arrhythmias and infarct size was investigated in a rat model of ischemia-...
