People with cardiac arrhythmia experience an irregular heartbeat. Irregular heartbeats are caused by illnesses, electrolyte imbalances and sometimes by unknown factors. Some arrhythmias linger silently for years, causing no problems or symptoms....
Magnesium is a metallic element that serves a variety of important functions in your body. Since magnesium is a component of chlorophyll, the main dietary sources of this important mineral come from the plant kingdom. According to nutritionist...
Cardiac arrhythmia is the medical term for an irregular heartbeat. Irregular heartbeats can include premature beats, slowed heartbeat, rapid heartbeat, atria fibrillation and ventricular arrhythmia. Since cardiac arrhythmia can be...
The heart normally beats in a rotating cycle of contraction and relaxation. This elegantly coordinated action is controlled by electrical impulses, which normally move across the heart with precision and reliability. When something goes awry with...
Cardiac arrhythmias include any interruption in the normal rate or rhythm of the heartbeat. Arrhythmias occur as a result of variations in the mechanical function, electrical conduction or electrolyte imbalances in the heart. Electrolytes, which...
The normal heart rate is between 60 and 100 beats per minute. If the heart beats faster or slower or produces erratic rhythms, it causes shortness of breath, loss of consciousness requiring hospitalization, cardiac arrest or even death. The...
Vitamin C, or ascorbic acid, is one of 13 vitamins your body needs for normal growth and healthy functioning. According to the Office of Dietary Supplements, the average recommended dietary allowance of vitamin C depends on your age; 90 mg is the...
Increased potassium, or hyperkalemia, interferes with the electrical currents of the body. The cells of the body rely on the flow of electrolytes such as sodium and potassium into and out of cells in order to function properly. Electrolyte...
Cardiac arrhythmias are caused by a disruption or abnormality in the electrical impulses of the heart. The heart is less efficient at pumping blood when the beats are too fast, too slow or when the beats are irregular. Cardiac arrhythmias are...
Supraventricular tachycardia, or SVT, is an abnormally fast heartbeat that occurs suddenly. It is triggered in the atria, or upper chambers, of the heart. People with SVT feel as if their heart is pounding out of their chest. Cardiac arrhythmias...
Heart muscle contractions are regulated by electricity that flows through the heart in a regular pattern. In some people, disruptions in this electrical system cause abnormal heart rhythms called arrhythmias. Some people must undergo a procedure...

High or low levels of potassium in the blood can cause significant health problems. Potassium is a nutrient that the human body needs to function properly. Some enzymes need potassium to work. Also, the heart, lungs and muscles require potassium...
Potassium is one of the six macrominerals -- meaning minerals whose dosages are based on gram amounts -- that your body requires. Potassium chloride is a form of potassium supplement used to replenish your potassium electrolytes, which can be lost...
Syncope is a neurologic condition in which a person temporarily loses consciousness. It may be associated with dizziness -- a sensation of unsteadiness and lightheadedness -- and confusion. As explained by the American Heart Association, syncope...
Some cardiac arrhythmia (also called dysrhythmia) have no underlying cause. Others, such as congenital abnormalities, are inherited or caused by gene mutations. The Cleveland Clinic reports that the most common causes of cardiac arrhythmia are...
According to the manufacturer, Avelox (moxifloxacin hydrochlorideis) a fluoroquinolone anti-microbial that is available for use to treat common community-acquired respiratory tract infections, including acute bacterial exacerbation of chronic...
As of 2011, taurine is considered a relatively new "heart-healthy" supplement. Early studies show promising effects of taurine supplementation when it comes to heart rate, blood pressure, muscle strength and possible cognitive benefits. Dr....
Coronary heart disease affects blood pressure. Heart disease leads to narrowing of the arteries that supply blood flow to the heart. Blood pressure control using medication and lifestyle approaches becomes essential for patients diagnosed with...
If you have a cardiac arrhythmia, you have a problem with the rate or rhythm of your heartbeat. The National Heart Lung and Blood Institute states that if you have arrhythmia, your pulse may be too fast or too slow. Your pulse may also possess an...
If you feel your heart racing and you become lightheaded and short of breath, you may be having an attack of atrial fibrillation, also known as cardiac arrhythmia. This condition occurs when your heart's upper and lower chambers beat out of synch....
Quinine is a medication that is used to treat malaria. Quinine is a naturally occurring plant substance that is native to South America. Currently, treatment of malaria is the only approved use of quinine by the U.S. Food and Drug Administration...
The human body works hard to maintain homeostasis, which means "steady state," with regard to different parameters. For instance, your body tries to maintain a constant temperature and acidity level. Similarly, you need stable levels of...
Heart disease is the leading cause of death in the United States, responsible for approximately 40% of all deaths, according to Mayo Clinic. It encompasses a broad group of diseases that affect the normal functioning of the heart. The chambers,...
Caffeine belongs to the list of several legal drugs that people around the world use on a day-to-day basis, according to the University of New Hampshire. More often than not, people consider it a harmless substance that has a little effect on the...
Calcium and magnesium are both dietary minerals essential to children's health. Childhood calcium deficiencies can cause rickets, a disease characterized by the softening and weakening of bones that can cause delayed growth, muscle weakness, bowed...
Although a variable heart rate or “cardiac arrhythmia” usually doesn’t produce noticeable symptoms, you might experience anxiety, dizziness, fainting and palpitations. Few herbs are recommended for helping to treat arrhythmias or...
The beating of your heart is a complex process that is initiated by an electrical impulse that starts at the sino-atrial node (SA), or natural pacemaker, at the top of the heart and spreads downward through the muscle in a precise pattern, causing...
Cardiac arrhythmia is a term covering a broad group of conditions that denote irregular electrical activity in the heart. Learn more about arrhythmias, including symptoms and treatments in this health video.
