Targeted drug therapy prevents exercise-induced arrhythmias

A 12-year-old Dutch boy - bedridden for three years because of an inherited cardiac arrhythmia syndrome - can now join his friends on the soccer field thanks to a discovery made by Vanderbilt University Medical Center researchers.

Heartbeat out of sync

Life-threatening cardiac arrhythmias often occur after a heart attack, as the scar tissue can interfere with the spread of electrical impulses that activate the heart. An international research team under the leadership of ...

Applied physics helps decipher the causes of sudden death

Sudden cardiac death accounts for approximately 10% of natural deaths, most of which are due to ventricular fibrillation. Each year, it causes 300,000 deaths in the United States and 20,000 in Spain. Researchers have demonstrated ...

Exercise may decrease heart drug's effectiveness

Peter Ruben and his team of researchers have spent years studying why seemingly healthy patients with inherited cardiac arrhythmias can sometimes suddenly die during exercise. (2017, 2016, 2015) His past research has shown ...

Sudden death during sport: Education to improve survival rates

More widespread availability of defibrillators and education of the general public could boost survival rates fourfold amongst athletes suffering cardiac arrest, a study has found. In less than half of cases, a bystander ...

Light tames lethal heart disorders in mice and virtual humans

Using high-tech human heart models and mouse experiments, scientists at Johns Hopkins and Germany's University of Bonn have shown that beams of light could replace electric shocks in patients reeling from a deadly heart rhythm ...

When the heart gets out of step

Atrial fibrillation is a cardiac arrhythmia -- a chronic irregularity of heartbeat -- which affects an estimated 1 million people in Germany. Although the condition is not acutely life-threatening, it does increase the risk ...

Dangers of adolescent energy drink consumption for the heart

The rapid rise in popularity of energy drinks (EDs), particularly among adolescents (aged 10-19 years) and young adults, has serious implications for cardiac health. In an article published in the Canadian Journal of Cardiology, ...

Stem cell technology could lead to ailing heart mending itself

For the first time, scientists can efficiently generate large numbers of rare cells in the network that pushes the heart's chambers to consistently contract. The technique, published May 28 in Stem Cell Reports, could be ...
