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.

Lilly receives FDA approval for Humulin R U-500 KwikPen

The U.S. Food and Drug Administration has approved Eli Lilly and Company's Humulin R U-500 KwikPen(insulin human injection) 500 units/mL, a pre-filled device containing Humulin R U-500, a highly concentrated formulation of insulin.

Researchers reconstruct 3D images of protein structures that link heart muscle cells in working groups

Diseased hearts may be thrown out of rhythm by structural differences -- now visible for the first time -- in protein groups that connect heart muscle cells, according to the authors of a study to be published in the journal Nature Communications online Jan. 20.

Pioneer calls on electrophysiologists to reexamine substrate mapping for deadly heart arrhythmia

A pioneer in developing life-saving therapies for a deadly heart arrhythmia has called on electrophysiologists to reexamine a widely used technique to guide the treatment of the faulty electrical impulses responsible for these abnormal heartbeats.

Electrical stimulation could regulate, synchronize beating properties of nascent heart muscle cells

Columbia Engineering researchers have shown, for the first time, that electrical stimulation of human heart muscle cells (cardiomyocytes) engineered from human stem cells aids their development and function.

Arrhythmias worth treating in PAH patients

Supraventricular arrhythmias are common in patients with pulmonary arterial hypertension but can be successfully managed with standard treatments, a study shows.

Sugary foods may affect recovery from heart attack

Scientists at the University of Leicester have demonstrated for the first time the mechanism by which the level of sugar in your blood can affect the contraction of blood vessels, with potentially dangerous effects on the heart and blood pressure.

Study findings question validity of some genetic variations linked with cardiac disorders

A review of medical records of patients with genetic variations linked with cardiac disorders found that patients often did not have any symptoms or signs of the conditions, questioning the validity of some genetic variations thought to be related to serious disorders, according to a study in the January 5 issue of JAMA.

Pacemaker Induced Transient Asynchrony could help slow down progression of heart failure

Johns Hopkins has demonstrated in animals that applying a pacemaker's mild electrical shocks to push the heart in and out of normal synchronized contraction for part of each day may be an effective way to slow down the progression of heart failure, a disorder that afflicts millions of Americans.

Researchers call for improved cause-of-death reporting to advance understanding of epilepsy

Recent studies conclude that people with epilepsy have a 27-fold greater risk of sudden death than people without the disorder. However, many of these deaths could be prevented through greater identification of epilepsy as a cause of death, and in educating the public more effectively about the disease's life-threatening dangers.

CAP2 gene responsible for cardiac conduction disease in mice

The presence or absence of the CAP2 gene causes sudden cardiac death in mice, according to new research from the Perelman School of Medicine at the University of Pennsylvania. In particular, the absence of the gene interrupts the animal's ability to send electrical signals to the heart to tell it to contract, a condition called cardiac conduction disease.

Advances in leadless pacing: an interview with Dr. Reddy

Pacemakers have been around for a very long time, they're great devices, critical for many people who have slow heartbeats. While they're very effective, they have some issues. There are two main aspects relating to these issues.

Screening for asymptomatic atrial fibrillation could reduce risk of stroke, premature death

Screening for asymptomatic atrial fibrillation (AF) in people aged 65 and over and treating it with anticoagulant medications could greatly reduce the risk of stroke and premature death, say cardiologists in today's Journal of the American Medical Association.

Researchers find way to predict occurrence of some cardiac arrhythmias

Researchers have discovered how to predict some cardiac arrhythmias several steps before they even occur. It's a finding that could lead to an improved cardiac device, with equipment designed to detect when arrhythmias are about to occur and then act to prevent them.
