An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.
A potent chemotherapy that is highly effective in treating the most common form of childhood leukemia can significantly harm the heart, but findings from a multi-center study
Fatal heart attacks claims more lives than lung cancer, breast cancer and AIDS combined but it seems that maths, not medicine, holds the key to preventing these deaths among young people.
Long-chain omega-3 polyunsaturated fatty acids (n-3 LC-PUFAs) have benefits regarding cardiovascular and inflammatory function, certain types of cancer, and maternal and infant health, according to recent peer-reviewed studies.
Innovative research by UTS engineers to apply microwave energy to the treatment of potentially deadly heart rhythm disorders has received an important boost from the National Health and Medical Research Council (NHMRC).
Cancer treatments, including the most commonly used chemotherapy agents as well as the newest biologic and targeted therapy drugs, can harm a patient’s heart, sometimes fatally
Thoracic surgeon Daniel Bethencourt, MD, one of the few cardiac surgeons to cure atrial fibrillation (rapid, irregular heartbeat) without opening the patient's chest, will perform endoscopic microwave ablation to treat atrial fibrillation in a 59-year-old man
Lower rates of sudden death among women may be related to gender differences in heart arrhythmias, rather than to other heart disease factors or treatments, hypertension, diabetes or other measured variables, according to a new study in the June 16, 2004 issue of the Journal of the American College of Cardiology.
In response to reports that women may be using an unapproved drug, domperidone, to increase milk production (lactation), the Food and Drug Administration (FDA) is warning breastfeeding women not to use this product because of safety concerns. Today, FDA also issued six letters to pharmacies that compound products containing domperidone and firms that supply domperidone for use in compounding.
Journal of the American Heart Association reports that exposure to air pollution can contribute to the development of cardiovascular diseases.
A Florida businessman filed suit today against Atkins Nutritionals, Inc., and the Estate of Dr. Robert C. Atkins, claiming that the late diet author’s controversial high-fat, low-carbohydrate regimen caused severe heart disease, necessitating angioplasty and a stent. He is seeking a court injunction banning Atkins Nutritionals from marketing its products without a warning of potential health risks and asks for compensatory damages.
Doctors prescribed different medications to control the cardiac arrhythmia, or abnormal heartbeat. But the medications slowed his heart rate too much, at times to as low as 40 beats per minute.
While adverse reactions from smallpox vaccinations given to military personnel in the wake of renewed threats of bioterrorism remain minimal, the rate of cardiac complications has been higher than expected, according to a clinical review presented at an American Medical Society media briefing on cardiology today.
However, surgical correction of certain forms of congenital heart disease may not fix the underlying molecular trigger that drives progressive heart failure and sudden death later in life, according to new research from the University of California, San Diego (UCSD) School of Medicine.
Hip fracture patients should be operated on within 24 hours of hospital admission because it reduces pain, shortens hospital stays and may limit the probability of major complications occurring, such as pneumonia and arrhythmias, according to the authors of a new study supported by the Agency for Healthcare Research and Quality.
Heart researchers at Columbia University Medical Center have developed and tested a unique heart arrhythmia drug that could prevent the sudden death of millions of people with heart failure as well as people with an inherited heart disorder. The drug represents one of the first molecular-based therapies for heart failure and avoids the toxicity of current treatments.
Researchers at Loyola University Health System, Maywood, Ill., and the University of Rochester Medical Center, Rochester, N.Y., found that the previously demonstrated survival benefit of ICDs following a heart attack can last up to 15 years.
Surgery to cut part of the nerves to the heart can reduce the risk of fainting or sudden death in young people with a heart rhythm disorder called long QT syndrome (LQTS), researchers reported in today’s rapid access issue of Circulation: Journal of the American Heart Association.
