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.

Age-related decline in cardiac conduction system regeneration increases arrhythmia risk after heart attack

Ablation may offer better outcomes than medication for ventricular tachycardia

Ablation, a procedure to treat abnormal electrical short circuits caused by a heart attack and is usually reserved for patients who do not improve with medication, may be a better first-line treatment for heart attack survivors experiencing dangerous rapid heartbeat episodes, according to late-breaking science presented today at the American Heart Association's Scientific Sessions 2024.
