Controlling cardiac waves with light to better understand abnormally rapid heart rhythms
Over 300,000 people die each year in the U.S. due to sudden cardiac death. In many cases, sudden cardiac death is caused by abnormally rapid heart rhythms called tachycardias, which means the heart cannot pump adequate blood ...

Study reveals how low oxygen levels in the heart predispose people to cardiac arrhythmias
Low oxygen levels in the heart have long been known to produce life-threatening arrhythmias, even sudden death. Until now, it was not clear how.

Lost in translation: The medium is the message for a healthy heartbeat
Researchers at the Fralin Biomedical Research Institute at Virginia Tech Carilion have revealed how a genetic message to produce healthy heart tissue is altered in the body during stress and aging to contribute to sudden ...

New study shows link between secondhand smoke and cardiac arrhythmia
Continuous indoor exposure to second-hand tobacco smoke triggers changes in the heart's electrical activity, known as cardiac alternans, that can predict cardiac arrhythmia and sudden cardiac death, a new study from UC Davis ...

Mitochondrial DNA could predict risk for sudden cardiac death, heart disease
Johns Hopkins researchers report that the level, or "copy number," of mitochondrial DNA—genetic information stored not in a cell's nucleus but in the body's energy-creating mitochondria—is a novel and distinct biomarker ...

A personalized virtual heart predicts the risk of sudden cardiac death
When electrical waves in the heart run amok in a condition called arrhythmia, sudden death can occur. To save the life of a patient at risk, doctors currently implant a small defibrillator to sense the onset of arrhythmia ...

Heart structural gene causes sudden cardiac death in animal model
The presence or absence of the CAP2 gene causes sudden cardiac death in mice, according to new research from the Perelman School of Medicine at the University of Pennsylvania. In particular, the absence of the gene interrupts ...
