Nervous system's role in fatal heart rhythm studied
Finding out why seemingly healthy people experience ventricular fibrillation, a fatal irregular heart rhythm, could eventually lead to better methods of early detection, according to a Medical College of Georgia researcher. view more (2005-12-23)
Day-long drivers at risk of cardiovascular problems as a result of traffic pollution
Exposure to fine particles and pollutants that accumulate in cars driving at varying speeds in road traffic enhances the likelihood of thrombosis, inflammation and alters the regularity of the heart rhythm. A study published today in the journal Particle and Fibre Toxicology raises concerns about cardiovascular risks for vehicle drivers. view more (2004-12-07)
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)
Concurrent imaging of metabolic and electric signals in the heart
Cardiac rhythm disorders can result from disturbances in cardiac metabolism. These metabolic changes are tightly linked with specific cardiac electrophysiology (CEP) abnormalities, such as depressed excitability, impaired intra- and extracellular conductivities, wave propagation block, and alteration of conduction velocity, action potential... view more...

Link between widely used osteoporosis drugs and heart problems probed
New research at Wake Forest University School of Medicine evaluated the link between a common class of drugs used to prevent bone fractures in osteoporosis patients and the development of irregular heartbeat. view more (2009-04-07)
Faulty body clock may make kids bipolar
Malfunctioning circadian clock genes may be responsible for bipolar disorder in children. Researchers writing in the open access journal BMC Psychiatry found four versions of the regulatory gene RORB that were associated with pediatric bipolar disorder. view more (2009-11-12)
Fruit fly research may lead to better understanding of human heart disease
Researchers at the Burnham Institute for Medical Research (Burnham) have shown in both fruit flies and humans that genes involved in embryonic heart development are also integral to adult heart function. The study, led by Rolf Bodmer, Ph.D., was published in Proceedings of National Academy of Sciences. view more (2008-12-02)
Atrial fibrillation linked to increased hospitalization in heart failure patients
Patients with atrial fibrillation, common in those with advanced chronic heart failure, have an increased risk of hospitalization due to heart failure. view more (2009-07-07)
Closing in on lethal heart rhythm in young athletes
Johns Hopkins experts on the genetics of a potentially lethal heart rhythm defect that runs in families and targets young athletes report they have greatly narrowed the hunt for the specific genetic mutations that contribute to the problem. view more (2006-09-08)
Consumption of fish oil does not appear to protect against abnormal heart rhythms
Patients with an implantable cardioverter defibrillator did not have a significantly lower risk of serious abnormal heart rhythms or death by consuming fish oil supplements, which had been thought to have a protective effect. view more (2006-06-14)
ESC Congress 2004: Atrial fibrillation patients often receive needless treatment
On behalf of the Euro Heart Survey on AF study group Management of AF in ESC countries: first lessons from the EuroHeartSurvey view more (2004-08-29)
A novel method to measure circadian cycles
The variation in individual circadian rhythms is an anecdotal as well as experimentally verified fact. But, until now, to systematically study circadian differences (and thereby hope to rout out the underlying genetic causes), scientists have had to rely on prolonged behavioural observation. view more (2005-09-27)
MIT: Leveraging learning for artificial respiration
MIT researchers have found that the body's innate ability to adapt to recurring stimuli could be leveraged to design more effective and less costly artificial respirators. view more (2007-09-12)
Patients who get ICDs for prevention have less driving restrictions
People who receive implantable cardioverter defibrillators (ICD) as a preventative measure don't need the same driving restrictions as people who get an ICD after surviving a life-threatening heart rhythm disturbance, according to an updated scientific statement. view more (2007-02-08)
3D Technology Pinpoints Origins of Irregular Heart Beats, Improving Patient Treatment
The findings of a new study published in the Journal of Cardiovascular Electrophysiology demonstrate that the use of high resolution imaging can greatly aid physicians who are treating patients suffering from a particular type of irregular heart beat. The study, conducted at the Taipei Veterans General Hospital in Taipei, Taiwan, provides insight... view more... (2004-06-11)
Increase in abnormal heart rhythms in shift workers
Shiftwork increases the risk of abnormal heart rhythms, shows research in Occupational and Environmental Medicine. These changes may help to explain why shiftworkers are susceptible to heart disease. Doctors measured changes in heartbeat and variations in heart rate in 49 employees working shifts, including nights, and 22 employees working normal... view more... (2001-09-07)
Study in NEJM: New therapy prevents heart failure
Patients who had a cardiac resynchronization device combined with a defibrillator (CRT-D) implanted had a 34 percent reduction in their risk of death or heart failure when compared to patients receiving only an implanted cardiac defibrillator (ICD). view more (2009-09-02)
Heart enlargement is a common cause of sudden death in young people (p 1881)
A seminar in this week's issue of THE LANCET highlights the frequency, diagnosis and management of hypertrophic cardiomyopathy, an unexplained thickening of the heart in young adults that has a 1% annual risk of sudden death. Dr. Perry Elliott from University College, London, UK and Professor William McKenna from The Heart Hospital, London state... view more... (2004-06-02)
Remote heartbeat monitor will outperform current technology
Doctors may be able to monitor a patient`s heartbeat from a distance by using a radical new sensor that is currently being developed at the University of Sussex in Brighton. view more (2002-01-29)
Whole-genome study at Johns Hopkins reveals a new gene associated with abnormal heart rhythm
Using a new genomic strategy that has the power to survey the entire human genome and identify genes with common variants that contribute to complex diseases, researchers at Johns Hopkins, together with scientists from Munich, Germany, and the Framingham Heart Study, U.S.A., have identified a gene that may predispose some people to abnormal heart... view more...
