Arrhythmia News and Research

RSS

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.

Herbals, surgery and anesthesia don't always mix

The woman who swears by gingko biloba wonders why her mouth won't stop bleeding after wisdom tooth surgery. What she doesn't know is that the herbal remedy she takes religiously to enhance mental alertness also acts as a powerful blood thinner that inhibits clotting.

First study about the influence of physical deconditioning on ventricular tachyarrhythmias

When athletes with irregular heartbeats are advised to stop intensive training, the arrhythmias often subside, and this response may help physicians decide which athletes may reenter competition, according to a new study in the Sept. 1, 2004 issue of the Journal of the American College of Cardiology.

First successful gene therapy that mimics the action of calcium channel blockers

Their findings - published in the latest edition of Circulation Research, online July 8 - may lead to a gene therapy alternative to calcium channel blockers and their sometimes severe side effects, but also further interest in the development of gene therapies unique - as in this case - to one particular organ.

Lower rates of sudden death among women may be related to gender differences in heart arrhythmias

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.

FDA warns against use of domperidone to increase milk production

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.
