Implantable cardioverter defibrillators account for one-third of the decrease in cardiac arrests caused by ventricular fibrillation in North-Holland, according to research in Circulation, an American Heart Association journal. VF is an abnormal heart rhythm that makes the heart quiver so it can't pump blood. ICDs are small electronic devices implanted in the chest that detect potentially fatal abnormal heart rhythms and try to stop them with electric shocks. Generally, only people with...

Transplanted heart cells, grown from stem cells, electrically couple and beat in sync with heart's own muscle Researchers have made a major advance in efforts to regenerate damaged hearts. Grafts of human cardiac muscle cells, grown from embryonic stem cells, coupled electrically and contracted synchronously with host muscle following transplantation in guinea pig hearts. The grafts also reduced the incidence of arrhythmias (irregular heart rhythms) in a guinea pig model of...

By: Katie Williams, Ivanhoe Health Correspondent (Ivanhoe Newswire)- Researchers have completed the first study of a procedure which uses three dimensional maps to determine the location of electrical signals in children´s hearts. This could help cardiologists correct rapid heart rhythms in young patients. Children who have atrioventricular nodal reentrant tachycardia, or AVNRT, suffer from disruptions in the heart's electrical system that causes sudden rapid heart rates. Patients...

University of Michigan heart researchers are shedding light on a safer method for steadying an abnormal heart rhythm that prevents collateral damage to healthy cells. Irregular heart rhythms, or arrhythmias, set the stage for a common, debilitating disorder called atrial fibrillation that puts adults as young as age 40 at risk for fatigue, fainting, cardiac arrest, and even death. Medications can help, but doctors also use catheter ablation in which electrical impulses are delivered to a...

Connie K. Ho for redOrbit.com Pumping vigorously night and day, the heart is clearly one of the most important organs in the human body. It is also one of the most delicate parts of the body. As such, news regarding heart-related diseases is beneficial to both doctors and patients. University of Michigan (UM) researchers recently reported the discovery of a new method that could produce cardiac muscle patches from stem cells. The innovative process was created at UM´s Center for...


Word of the Day
tesla
  • The unit of magnetic flux density in the International System of Units, equal to the magnitude of the magnetic field vector necessary to produce a force of one newton on a charge of one coulomb moving perpendicular to the direction of the magnetic field vector with a velocity of one meter per second. It is equivalent to one weber per square meter.
This word is named for Nikola Tesla, the inventor, engineer, and futurist.
