Heart Rate News and Research

RSS

Heart rate is determined by the number of heartbeats per unit of time, typically expressed as beats per minute (BPM), it can vary with as the body's need for oxygen changes, such as during exercise or sleep.

Three papers reveal structure and workings of G protein-coupled receptors

Three international teams of scientists, led by researchers at the University of California San Diego, University of Michigan and Stanford University, have published a trio of papers describing in unprecedented detail the structure and workings of G protein-coupled receptors (GPCRs), a large family of human proteins that are the target of one-third to one-half of modern drugs.

University of Utah develops video game to help children with cancer

Even super heroes need a chance to get better, especially if they've been fighting their arch-nemesis and a robotic crab that just won't go away. At least, that's the premise behind a video game developed at the University of Utah to help children with cancer during their treatment.

Levosimendan may effectively improve muscle function in patients with respiratory failure

Treatment with the calcium-sensitizing drug levosimendan may be effective in improving muscle function in patients with respiratory muscle weakness, which often accompanies chronic diseases such as chronic obstructive pulmonary disease (COPD) and congestive heart failure, according to researchers in the Netherlands, who studied the effects of the drug on healthy volunteers.

Infant formulas fortified with LCPUFA are good for developing brains and hearts

University of Kansas scientists have found new evidence that infant formulas fortified with long chain polyunsaturated fatty acids (LCPUFA) are good for developing brains and hearts.

Noninvasive method can detect sudden infant death syndrome, sleep apnea

University of Utah engineers who built wireless networks that see through walls now are aiming the technology at a new goal: noninvasively measuring the breathing of surgery patients, adults with sleep apnea and babies at risk of sudden infant death syndrome.

Anti-nausea drug Zofran being tested for its potential heart rhythm side effects

The United States health regulators Food and Drug Administration (FDA) are looking at the safety of GlaxoSmithKline's anti-nausea drug Zofran generically known as ondansetron, to ascertain whether there is a potential risk of abnormal heart rhythm.

'Talk Test' effective for gauging exercise intensity

New research by University of New Hampshire exercise scientists confirms that a low-tech, easy-to-administer test is an effective tool for gauging exercise intensity, but that it does not correspond as neatly as previously assumed to other more objective tests.

Researchers describe new function of HCN channels in the heart

The heartbeat is the result of rhythmic contractions of the heart muscle, which are in turn regulated by electrical signals called action potentials. Action potentials result from the controlled flow of ions into heart muscle cells (depolarization) through channels in their membranes, and are followed by a compensating reverse ion current (repolarization), which restores the original state. If the duration of the repolarization phase is not just right, the risk of ventricular arrhythmia and sudden cardiac death increases significantly.

Study: Aerobic physical activity linked to reduced risk of dementia

Any exercise that gets the heart pumping may reduce the risk of dementia and slow the condition's progression once it starts, reported a Mayo Clinic study published this month in Mayo Clinic Proceedings.

Top-line results from Teva-Alcobra MG01CI Phase II trial for ADHD

Teva Pharmaceutical Industries Ltd. and Alcobra Ltd. announced today top-line results from a six week, randomized, placebo-controlled, Phase II multi-center study designed to assess the safety and efficacy of MG01CI in adults with attention deficit hyperactivity disorder (ADHD).

Combination of resistance training, AT does not benefit cardiac patients

For patients undergoing rehabilitation following cardiac events, aerobic exercise training (AT) is widely recommended. Resistance training (RT) has also been shown to be beneficial because it enhances muscular strength and endurance, functional capacity and independence, and quality of life, while reducing disability.

Longer CPR may do more harm than good: Study

A new study reveals that providing CPR (cardiopulmonary resuscitation) for a longer period of time could actually harm certain patients. “We found that extra CPR didn't help and, in fact, in some patients it was not a good thing. It would make it worse,” said Dr. Ian Stiell, lead author of a paper published in the Sept. 1 issue of the New England Journal of Medicine. “Our study showed that there's no reason to do two minutes of CPR or to delay defibrillation.”

Aerobic exercise best for belly fat reduction: Study

A new study has shown that the best type of exercise to burn unhealthy belly fat is aerobic exercise. The results showed that people who did aerobics for eight months lost about 2.5 square inches of belly fat, as measured on a CT scan. That's about 1.5 times as much as people who did a combination of aerobic exercise and weight lifting, and about 20 times as much as those who only lifted weights.

Positive results from Bionovo's Menerba tolerability trial on menopausal hot flashes

Bionovo, Inc., a pharmaceutical company focused on the discovery and development of safe and effective treatments for women's health and cancer, today announced the positive results from the completion of their tolerability trial of Menerba (MF101) for menopausal hot flashes.

Ivabradine reduces heart volume among patients with cardiac insufficiency

As guest speaker at the European Society of Cardiology's Congress currently under way in Paris, Dr. Jean-Claude Tardif, Director of the Montreal Heart Institute's Research Centre and professor of medicine at the Universit- de Montr-al, today presented the results of an analysis demonstrating that ivabradine, a medication used to reduce heart rate, also reduces heart volume (left ventricle) among patients with cardiac insufficiency.

Strong link between leisure-time physical activity and AF among men

A Norwegian survey carried out between 1974 and 2003 showed that there was a graded independent increase in the risk of AF with increasing levels of physical activity in a population-based study among men with ostensibly no other heart disease. In women the data were inconclusive.

Fludrocortisone may help reduce unexplained chronic nausea in children

Heart rate and blood pressure regulation may hold the key to treating unexplained chronic nausea in children. In a new study by researchers at Wake Forest Baptist Medical Center, a drug commonly used to treat a condition known as orthostatic intolerance (OI), which causes dizziness and occasional fainting when patients stand for long periods, was shown to reduce debilitating chronic nausea in patients.
