Arrhythmia News and Research

RSS

An arrhythmia is a problem with the speed or rhythm of the heartbeat. During an arrhythmia, the heart can beat too fast, too slow, or with an irregular rhythm. A heartbeat that is too fast is called tachycardia. A heartbeat that is too slow is called bradycardia. Most arrhythmias are harmless, but some can be serious or even life threatening. When the heart rate is too slow, too fast, or irregular, the heart may not be able to pump enough blood to the body. Lack of blood flow can damage the brain, heart, and other organs.

A Novel Genetic Inference Method for Detecting Rare Disease Variants

Undiagnosed cases of Long QT syndrome have been found, thanks to an inventive examination of shared genomic sequences, which is a sign of distant “relatedness” and can cause irregular heart rhythms, fainting, and sudden cardiac death.

Radiation therapy can reprogram heart muscle cells to a younger state, suggests study

New research from Washington University School of Medicine in St. Louis suggests that radiation therapy can reprogram heart muscle cells to what appears to be a younger state, fixing electrical problems that cause a life-threatening arrhythmia without the need for a long-used, invasive procedure.

Study finds no evidence that caffeine consumption leads to greater risk of arrhythmias

In the largest study of its kind, an investigation by UC San Francisco has found no evidence that moderate coffee consumption can cause cardiac arrhythmia.

Study shows how scar tissue can effectively regenerate the injured heart

It is estimated that during a heart attack, one billion cells in the heart are lost. In the wake of the heart attack, the lost tissue is replaced by scar tissue, which can lead to heart failure, arrhythmia and death. In a new study, researchers from the University of Tsukuba have shown how cells in the scar tissue can be converted to heart muscle cells, effectively regenerating the injured heart.

Drug meant for bacterial infections can combat weight gain

A drug originally developed to treat bacterial infections has proved capable of boosting the metabolism and attenuating the weight gain induced by a fatty diet in tests with mice. The study was conducted at the University of Campinas (UNICAMP) with FAPESP's support, and the findings have just been published in the journal Science Advances.
