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.

Catheter ablation safe for patients

A recent study published in Pacing and Clinical Electrophysiology (PACE) determined that the use of catheter ablation to treat supraventricular tachycardia (SVT) is not detrimental to patients.

Protein in cardiac muscle cells may play a crucial role in heart failure prevention

Scientists at the University of North Carolina at Chapel Hill School of Medicine have shown that a protein in cardiac muscle cells may play a crucial role in heart failure prevention.

Study is the first to track changes in the rate of ICD utilization among blacks and whites

Racial disparities in the use of implantable cardioverter-defibrillators (ICDs) declined during the 1990s as use of the devices spread into communities with larger African-American populations, according to a new study in the Jan. 4, 2005 issue of the Journal of the American College of Cardiology.

May soon be possible to identify people at risk and even to treat a heart problem with a drug that works on the brain

Sudden cardiac death from emotional stress may be triggered by uneven signals from the brain to the heart, according to a study by University College London (UCL) scientists published in the January issue of Brain.

Biological clock affects the patterns of heart-rate control in healthy individuals

In a newly reported, first-ever finding, physicists from Boston University and physiologists from Boston’s Brigham and Women’s Hospital (BWH) have found that the body’s biological clock affects the patterns of heart-rate control in healthy individuals independent of sleep/wake cycle or other behavior influences.

Landmark revascularization procedure

The People's Hospital of Beijing University performed a combined revascularization procedure utilizing beating heart bypass surgery, along with transmyocardial revascularization and stem cell implantation.

Revlimid clinical data in newly diagnosed multiple myeloma presented

Celgene Corporation announced today that data evaluating clinical results on Revlimid (lenalidomide) as a new therapeutic approach for patients with newly diagnosed multiple myeloma (MM) was presented at the American Society of Hematology 46th Annual Meeting in San Diego.

Acetaminophen shows positive cardioprotective effects In heart attack, arrhythmia

Long an under-studied yet widely-used over-the-counter medication, acetaminophen over the last few years is becoming recognized for a range of potential therapeutic uses beyond headache and pain.

Women with arrhythmias may also benefit from implantable cardioverter-defibrillators

A small study of patients with heart failure not caused by blocked arteries indicates that women, as well as men, may benefit from implantable cardioverter-defibrillators (ICD), reported researchers at the American Heart Association’s Scientific Sessions 2004.

Bretylium tosylate has unique benefits for patients with acute myocardial infarction

An "old" drug has unique benefits for patients with acute myocardial infarction (AMI; commonly known as heart attack), a finding that may contribute to a new understanding of how heart attacks develop, according to an article in the September/October American Journal of Therapeutics.

Heart arrhythmias easily treated, yet few know risks

Since she was a young girl, Sandra Moore, 46, of Glen Ellyn, Ill., had episodes every few months when her heart started racing.

Women who have diets rich in oils containing alpha-linolenic appear to have a lower risk of dying from heart disease

Women who reported eating diets rich in oils containing alpha-linolenic acid (ALA) seemed to have a lower risk of dying from heart disease and sudden cardiac death than women whose diets are low in the plant-derived fatty acid, researchers reported at the American Heart Association’s Scientific Sessions 2004.

Doctors must choose and manage implanted cardiac defibrillators patients carefully

Implanted devices that can shock a failing heart back into regular rhythm do an excellent job of keeping patients alive, two new University of Michigan studies find.

8 Nov 2004

Mild pulses of electrical energy just as effective as more powerful and painful shocks to interrupt life-threatening rapid heartbeats

Ventricular tachycardia (VT) is a fast heartbeat originating in the heart’s ventricle chamber and can be life-threatening. VT is often treated with an implantable cardioverter-defibrillator (ICD), a device that delivers an electrical shock to restore an irregular heart rhythm.

One in four deaths among women with heart failure can be attributed to kidney problems

About one in four deaths among women with heart failure can be attributed to kidney problems, and more deaths are linked to renal insufficiency than to any other single risk factor, according to a new study in the Oct. 19, 2004 issue of the Journal of the American College of Cardiology.

Study links possible role of ephedrine in sudden cardiac arrests

Each year 80,000 - 100,000 people in the U.S die suddenly from heart attacks without ever having had any symptoms of heart disease. In some cases, the victims of these unheralded sudden cardiac deaths had been taking dietary supplements containing ephedrine.

Researchers pinpoint genetic cause of Timothy syndrome

Howard Hughes Medical Institute researchers have pinpointed the genetic cause of a devastating but rare childhood disorder, called Timothy syndrome, which underlies a form of severe cardiac arrhythmia.

Draft Medicare plan to cover implantable defibrillators

The Centers for Medicare & Medicaid Services (CMS) today proposed to expand coverage of implantable cardioverter defibrillators (ICDs), a move expected to save thousands of lives a year.

Celacade shown to reduce risk of death and hospitalization in patients with advanced chronic heart failure

Vasogen has announced that comprehensive results from the Company's phase II trial of Celacade (immune modulation therapy) in advanced chronic heart failure patients were published in the September 15 issue of the Journal of the American College of Cardiology (JACC).

Findings that may help explain links between the stress of traumatic events and increased risk of cardiac death

Reporting findings that may help explain links between the stress of traumatic events and increased risk of cardiac death, researchers said the rate of potentially life-threatening heart arrhythmias doubled during the month after the World Trade Center terrorist attack in 2001 in patients with implantable cardioverter-defibrillators, not only in the New York area, but also in Florida
