Arrhythmia News and Research RSS Feed - Arrhythmia News and Research

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.
One in four people with implanted defibrillators experiences improvements in heart function

One in four people with implanted defibrillators experiences improvements in heart function

A Johns Hopkins-led study of outcomes among 1,200 people with implanted defibrillators -- devices intended to prevent sudden cardiac death from abnormal heart rhythms -- shows that within a few years of implantation, one in four experienced improvements in heart function substantial enough to put them over the clinical threshold that qualified them to get a defibrillator in the first place.

Simple process for obtaining induced pluripotent stem cells without use of reagents

Simple process for obtaining induced pluripotent stem cells without use of reagents

For their ability to differentiate into other cell types, the embryonic stem cells hold a large potential in the medical industry. Their use, however, poses ethical questions due to the fact that in order to obtain them, it is necessary to destroy the embryo. For this reason, medical researches use the so-called induced pluripotent stem cells (iPSC). In fact, it is possible to reprogram adult cells that can be obtained by simply drawing blood and making them "regress" to a similar state to that of embryonic stem cells. [More]
