Protective effect of pharmacologic postconditioning with Natural Honey against left ventricular ischemia/reperfusion-induced arrhythmias in isolated heart of rat
Introduction: This study was aimed to investigate the effects of postconditioning by natural honey on cardiac arrhythmias in the ischemic isolated rat heart. Methods: Male Wistar rats were divided into four groups then anesthetized by sodium pentobarbital. The animal hearts were removed and quickly mounted on a Langendorff apparatus and perfused under constant pressure by a modified Krebs-H...
متن کاملStretch-induced ventricular arrhythmias during acute ischemia and reperfusion.
Mechanical stretch has been demonstrated to have electrophysiological effects on cardiac muscle, including alteration of the probability of excitation, alteration of the action potential waveform, and stretch-induced arrhythmia (SIA). We demonstrate that regional ventricular ischemia due to coronary artery occlusion increases arrhythmogenic effects of transient diastolic stretch, whereas global...
متن کاملSuppression of ischemic and reperfusion ventricular arrhythmias by inhalational anesthetic-induced preconditioning in the rat heart.
Inhalational anesthetic-induced preconditioning (APC) has been shown to reduce infarct size and attenuate contractile dysfunction caused by myocardial ischemia. Only a few studies have reported the effects of APC on arrhythmias during myocardial ischemia-reperfusion injury, focusing exclusively on reperfusion. Accordingly, the aim of the present study was to examine the influence of APC on vent...
متن کاملRanolazine, an antianginal agent, markedly reduces ventricular arrhythmias induced by ischemia and ischemia-reperfusion.
We tested the effect of the antianginal agent ranolazine on ventricular arrhythmias in an ischemic model using two protocols. In protocol 1, anesthetized rats received either vehicle or ranolazine (10 mg/kg, iv bolus) and were subjected to 5 min of left coronary artery (LCA) occlusion and 5 min of reperfusion with electrocardiogram and blood pressure monitoring. In protocol 2, rats received eit...
متن کاملThe clinical significance of exercise-induced ventricular arrhythmias.
A32-year-old male pharmacist complained of having had palpitations for the past month. Using his index finger and tapping the table top, he replicated a pattern that simulated extrasystoles. He exercised daily, running 3 miles and lifting weights for 1⁄2 hours and was asymptomatic prior to, during, and after exercise. There was no past history of illness or allergies, and he was not taking any ...
