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.

Fibroblast research could lead to alternatives to implanted electronic pacemakers

In guinea pig experiments, Johns Hopkins scientists fused common connective tissue cells taken from lungs with heart muscle cells to create a safe and effective biological pacemaker whose cells can fire on their own and naturally regulate the muscle's rhythmic beat.

Lay people can effectively use defibrillators to save the lives of cardiac arrest victims

The first large-scale study to see whether trained volunteers and lay people can use defibrillators to save the lives of cardiac arrest (CA) victims has concluded that their use by lay people is safe, and if the response time can be shortened to within eight minutes there is the potential to save the lives of 15 out of 100 people who collapse suddenly with CA.

Beta-blockers may help deal with stress

An experience as simple as watching graphically violent or emotional scenes in a movie can induce enough stress to interfere with problem-solving abilities, new research at Ohio State University Medical Center suggests.

Heart defect caused 4-year-old to die on Disney ride

According to a Florida autopsy report a 4-year-old boy who collapsed in June after riding a rocket simulator at Walt Disney World had a serious heart defect which caused his death.

Ultrasound to view heart's interior in three dimensions

Duke University engineers are developing technology that may enable physicians to someday use high frequency ultrasound waves both to visualize the heart's interior in three dimensions and then selectively destroy heart tissue with heat to correct arrhythmias.

MRI measurements of scar tissue accurately predict the risk of arrhythmia-related sudden death

Using magnetic resonance imaging (MRI) scans of the heart wall, researchers at Johns Hopkins have found that people whose muscle wall thickness contained more than 25 percent scar tissue were approximately nine times more likely to test positive for a fast and dangerous heart rhythm known as ventricular arrhythmia.

Link between the act of lying and a significant increase in gastric arrhythmia

A new study suggests that changes in gastric physiology perform better than standard polygraph methods in distinguishing between lying and telling the truth.

When it comes to telling lies it's the stomach not the heart which is the giveaway

According to a new study it is suggested that it is the stomach rather than the heart that offers greater lie detection accuracy.

Defibrillator implantations performed by physicians with low volume are more likely to have adverse outcomes

As the implantation of cardioverter-defibrillator devices to prevent sudden cardiac death becomes increasingly popular, patients are likely to get the best results when they are treated by physicians who perform the procedures frequently, according to a new study in the Oct. 18, 2005, issue of the Journal of the American College of Cardiology.

Recommendations for fellowship training in pediatric cardiology

The American College of Cardiology Foundation (ACCF), the American Heart Association (AHA), and the American Academy of Pediatrics (AAP) have joined forces to develop important first-ever recommendations for fellowship training in pediatric cardiology.

Heavy alcohol consumption can significantly increase men's risk of developing atrial fibrillation

A large-scale study led by researchers at Beth Israel Deaconess Medical Center (BIDMC) has found that heavy alcohol consumption - 35 or more drinks per week -- can significantly increase men's risk of developing atrial fibrillation, a dangerous type of arrhythmia and one of the leading risk factors for stroke.

Low-dose aspirin might prevent the cardiovascular damage known to arise from use of the painkiller rofecoxib (Vioxx)

Their findings that a chemical imbalance might underlie such damage could also lead to the development of anti-inflammatory drugs without the adverse side effects, the researchers said.

Women with atrial fibrillation face a higher risk of ischemic stroke than men

Women with atrial fibrillation who are not on anticoagulant therapy have a higher rate of ischemic stroke and face a higher absolute risk for stroke than do men with the condition, according to a joint study

Study - no effect of fish oil on life-threatening cardiac arrhythmia

In patients with an increased risk of heart rhythm problems, cardiac arrest or arrhythmia, eating fish oil did little to reduce that risk.

Catheter interventions help to prevent stroke

According to WHO statistics, stroke is the second most frequent cause of death worldwide. Cardiac causes account for up to 20% of strokes. Transcatheter occlusion of patent foramen ovale and left atrial appendage eliminate the most important sources for cardiac embolism.

Advice to cardiac patients regarding sports and exercise

Increased levels of physical activity are known today to be one of the most powerful protective factors against cardiovascular disease and its progression.

Beta-blockers top choice for prevention and rate control for postoperative atrial fibrillation

The American College of Chest Physicians (ACCP) has released the first evidence-based clinical practice guidelines for the prevention and management of postoperative atrial fibrillation (AF) after cardiac surgery.

Innovation that helps locate and treat life-threatening heart arrhythmias

The Research Foundation of SUNY, which supports the advancement of education, research and discovery at the State University of New York, today announced it signed a licensing agreement with Biosense Webster Inc. for the rights to an Upstate Medical University innovation that helps locate and treat life-threatening heart arrhythmias.

Human dummy to teach medics

A new way to teach medical students will be demonstrated for the first time at Bristol University on 21 July 2005, during a joint meeting of the Physiological Society and the Federation of European Physiological Societies.

Study warns against global use of old asthma medicines for kids' coughs

An asthma medicine widely used around the world to stop children's coughs has no provable benefit for that purpose and may cause harm, a new review of existing studies reports.
