Stress and Cardiac Arrhythmias
Stress can exert adverse effect on cardiovascular health. Psychosocial stress adversely affects the autonomic homeostasis. This in turn can result in metabolic abnormalities, inflammation and dysfunction of endothelium [1]. Changes in the autonomic homeostasis can be a major trigger for ventricular tachyarrhythmias [2]. Increased sympathetic nervous activity can cause increased proarrhythmic re...
متن کاملEvaluation the Protective Role of Gallic Acid on Cardiac Arrhythmias Induced by Oxidative Stress in Rat Exposure to Particulate Matters
Introduction: Particulate matter (PM) increases the risk of heart disorders. Gallic acid (GA) with strong antioxidant properties has shown an effective role in reducing the complications of various diseases. The aim of this study was to evaluate the protective effect of Gallic acid in preventing cardiac arrhythmias due to exposure to particulate matter. Methods: In this study, 40 rats were pla...
متن کاملRole of Stress in Cardiac Arrhythmias.
Stress is a major trigger of cardiac arrhythmias; it exerts profound effects on electrophysiology of the cardiomyocytes and the cardiac rhythm. Psychological and physiological stressors impact the cardiovascular system through the autonomic nervous system (ANS). While stressors vary, properties of the stress response at the level of cardiovascular system (collectively referred to as the autonom...
متن کاملEllagic acid improved arrhythmias induced by CaCL2 in the rat stress model
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...
متن کاملChannel structure and drug-induced cardiac arrhythmias.
E lectrical activity underlies the control of the frequency, strength, and duration of contraction of the heart. During the cardiac cycle, a regular rhythmic pattern must be established in time-dependent changes in ionic conductances to ensure events that underlie normal cardiac function. Electrical impulses, originating at the sino atrial node are conducted throughout the atria until they conv...
