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.

Scientists discover 23 new genes linked to heart rhythm

Scientists discover 23 new genes linked to heart rhythm

The QT interval is part of the heart's electrical cycle as measured by ECG, and represents the electrical depolarization and repolarization of the ventricles. Lengthened intervals indicate dysfunction in the heart beat and are liable to lead to a five-fold increase in the risk of sudden death from heart failure. [More]
Use of catheter ablation lowers risk for atrial fibrillation

Use of catheter ablation lowers risk for atrial fibrillation

Use of catheter ablation is not only beneficial for treating atrial flutter but also can significantly reduce hospital visits - both inpatient and emergency - and lower the risk for atrial fibrillation, according to research by UC San Francisco. [More]
