Protective effects of gallic acid on cardiac electrophysiology and arrhythmias during reperfusion in diabetes
Objective(s): Gallic acid (GA), a potent anti-oxidant, plays an important role in reducing diabetic induced cardiac disorders. Therefore, the present investigation was purposed to determine the beneficial effect of GA in cardiac arrhythmias during reperfusion in diabetes induced by alloxan. Materials and Methods: Male Sprague-Dawley rats...
متن کاملIntroduction to Cardiac Electrophysiology, the Electrocardiogram, and Cardiac Arrhythmias
Overall cardiac output (the amount of blood the heart pumps around the body every minute) is a function of how much blood the heart ejects with every beat, and the heart rate. Many factors work in concert to regulate heart rate. A thorough understanding of normal mechanisms of cardiac electrical activation and modifying factors is a necessary precursor to understanding disease states, and their...
متن کاملRole of K+ channel activators in cardiac electrophysiology and arrhythmias.
T he search for new antiarrhythmic agents has long centered around drugs capable of inhibiting one or more of the ionic currents responsible for transmembrane activity in cardiac tissues and drugs capable of interfering with the influence of the autonomic nervous system on the heart. As a consequence, we are today equipped with an armamentarium of sodium, calcium, and potassium channel blockers...
متن کاملComputational approaches to understand cardiac electrophysiology and arrhythmias.
Cardiac rhythms arise from electrical activity generated by precisely timed opening and closing of ion channels in individual cardiac myocytes. These impulses spread throughout the cardiac muscle to manifest as electrical waves in the whole heart. Regularity of electrical waves is critically important since they signal the heart muscle to contract, driving the primary function of the heart to a...
متن کاملInnovations in heart rhythm disturbances: cardiac electrophysiology, arrhythmias, and cardiac pacing.
This article reviews the most relevant articles published in 2012 in the field of arrhythmias, on subjects that include clinical arrhythmology, ablation, cardiac pacing, and the genetics of sudden cardiac death.
