Slowing the racing heart
Researchers at the University of Illinois at Chicago explain in the May 11 issue of Circulation Research how an enzyme acts on the heart's pacemaker to slow the rapid beating of the heart's "fight-or-flight" reaction to adrenaline.   view more (2007-05-14)

iPods and similar devices found not to affect pacemaker function
Last May, a widely reported study concluded that errant electronic noise from iPods can cause implantable cardiac pacemakers to malfunction. This just didn't sound right to the cardiac electrophysiologists at Children's Hospital Boston, who've seen hundreds of children, teens and young adults with... view more (2008-03-31)

ESC Congress 2003: Can we make a new sinus node? The promises of genetically engineered bio-pacemakers
IMPORTANT: This press release accompanies both a presentation and an ESC press conference given at the ESC Congress 2003. Written by the investigator himself/herself, this press release does not necessarily reflect the opinion of the European Society of Cardiology Heart block is a condition in... view more (2003-09-01)

Scientists provide new evidence for cellular cause of SIDS
University of Chicago researchers and colleagues have found strong support that a disturbance of a specific neurochemical can lead to sudden infant death syndrome, the primary cause of death before age 1 in the United States.   view more (2006-03-08)

Aggressive heart pacing may work best in some spinal cord patients
Patients with recurring problems with the heart slowing or stopping after a neck injury damages their cervical spinal cord may need aggressive therapy to avoid further cardiovascular problems and even death, Medical College of Georgia researchers say.   view more (2006-07-24)

Scientists in Japan design first optical pacemaker for laboratory research
The world's first optical pacemaker is described in an article published today in Optics Express, the Optical Society's open-access journal. A team of scientists at Osaka University in Japan show that powerful, but very short, laser pulses can help control the beating of heart muscle cells.   view more (2008-05-28)

MDCT angiography for cardiac imaging: Reliable tool, less invasive, fewer complications
A new procedure for the imaging of coronary veins proves to be "less invasive, have less complications, and improves the quality of diagnosis and treatment " for individuals undergoing surgical procedures on the heart and particularly the coronary veins, a recent study found.   view more (2005-12-30)

Engineering electrically conducting tissue for the heart
Patients with complete heart block, or disrupted electrical conduction in their hearts, are at risk for life-threatening rhythm disturbances and heart failure.   view more (2006-06-19)

Pacemaker tune-up works chemical wonders on damaged hearts in dogs
Using pacemakers to electrically retune a heart damaged by long bouts of a wobbling heartbeat, where one heart muscle wall is beating sooner than the other, leads to fast improvements in the tissue levels of more than a dozen proteins key to the organ's health, scientists at Johns Hopkins report in... view more (2008-03-06)

UCLA develops unique nerve-stimulation epilepsy treatment
A unique nerve-stimulation treatment for epilepsy developed at UCLA offers a potential new alternative for tens of thousands of individuals unable to control their seizures with medication and ineligible for surgery.   view more (2006-07-26)

Aetiology of congenital heart disease explained
Researchers at Karolinska Institutet have identified the mechanisms behind the serious, congenital heart condition that can sometimes develop in children of women with a rheumatic disease.   view more (2005-02-07)

Pacemakers Could Protect Patients With Epilepsy From Sudden Unexplained Death (pp 2157, 2212)
Results of a UK study in this week's issue of THE LANCET highlight how interruptions to the heart's rhythm is an under-reported consequence of epileptic seizures, and that the use of cardiac pacemakers by some epilepsy patients could play a future role in protecting against sudden unexplained death.   view more (2004-12-15)

ESC Congress 2003: Left ventricular pacing alone has similar benefits to those of biventricular pacing in patients with severe heart failure
IMPORTANT: This press release accompanies a poster or oral session given at the ESC Congress 2003. Written by the investigator himself/herself, this press release does not necessarily reflect the opinion of the European Society of Cardiology Our study shows that left ventricular and biventricular... view more (2003-09-01)

UC Davis researchers move biotechnology closer to replacing electronic pacemakers
UC Davis researchers have successfully used a custom designed protein and gene delivery system to restore normal heart rhythms in pigs with electronic pacemakers, reducing their dependence on implanted devices.   view more (2006-08-23)

Mass. General researchers identify master cardiac stem cell
Researchers from the Massachusetts General Hospital (MGH) Cardiovascular Research Center have discovered what appears to be a master cardiac stem cell, capable of differentiating into the three major types of cells that make up the mammalian heart.   view more (2006-11-27)

Central and peripheral signals set the circadian liver clock
Anyone who has experienced jet lag will understand the importance of a smooth-running circadian clock. Crossing time zones decouples our biological rhythms from the natural cycle of light and dark we're used to.   view more (2007-01-30)

Hospital mortuary services need regular inspection
Recent stories about improper storage of bodies and organs in hospital mortuaries have generated public interest in both pathology and mortuary services.   view more (2002-04-24)

Dangerous technology -- Mobiles should be kept away from hospital beds
Mobile phones should come no closer than one meter to hospital beds and equipment, according Dutch research published in the online open access journal, Critical Care.   view more (2007-09-06)

Fish oil prevents potentially deadly decline in heart rate variability
A two-gram fish oil supplement given daily to elderly persons prevented a decline in heart rate variability caused by tiny, dangerous airborne pollutant particles.   view more (2005-12-16)

No pacemakers in the brain may explain cot death
A failure to 'gasp' has long been proposed as the basis for sudden infant death syndrome, or cot death.   view more (2006-02-13)

Thinking about moving? Let brain waves do the walking
Using brain waves to control screen cursor movements, rather than moving a mouse by hand, seems like science fiction! Yet such direct control over our environment is an integral part of the development work being undertaken by participants in the Presencia project.   view more (2004-12-02)

Gene controlling circadian rhythms linked to drug addiction, UT Southwestern researchers find
The gene that regulates the body's main biological clocks also may play a pivotal role in drug addiction, researchers at UT Southwestern Medical Center have found.   view more (2005-06-14)

New data finds recalls of automated external defibrillators to be common
Data presented today at the Heart Rhythm Society's 27th Annual Scientific Sessions finds that during a 10-year study period more than one in five automatic external defibrillators (AEDs) were recalled due to potential malfunction.   view more (2006-05-19)

Mayo Clinic discovery may help diabetic gastric problem
Mayo Clinic researchers have found what may provide a solution to one of the more troubling complications of diabetes -- delayed gastric emptying or gastroparesis.   view more (2008-09-26)

Keeping the body in sync — The stability of cellular clocks
A study in Switzerland uses the tools of physics to show how our circadian clocks manage to keep accurate time in the noisy cellular environment.   view more (2007-03-13)
