What is it? A pacemaker is a small battery-operated device that’s placed in the chest or abdomen to help control abnormal heart rhythms. Some pacemakers are external and temporary‚ not surgically implanted. The primary purpose of a pacemaker is to maintain an adequate heart rate‚ either because the heart’s natural pacemaker is too slow‚ too fast or has an irregular rhythm‚ this problem is called arrhythmias.

Background Heart failure (HF) is a condition in which the heart muscles lose its ability to pump sufficient blood to the body. It’s considered as one of the leading causes of death in the U.S with an estimated direct and indirect cost of $39 billion per year.1 Bioenergetics dysfunction is common in HF patients‚ which leads to energy starvation of the cardiac cells.2 Therefore‚ some medical providers encourage their patients to take ubiquinone‚ a lipid-soluble antioxidant‚ as an adjunct HF therapy

Introduction: The human body is incredible machinery that can adjust to stressful situations and react in a “fight-or flight” manner by temporarily shutting off nonessential‚ at the moment‚ immune and digestive systems. When the body is ready for a challenge‚ heart rate increases‚ blood pressure rises and glucose production intensifies to supply large amounts of energy. These metabolic changes are caused by release of stress hormones (catecholamine
