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.

New statement suggests next steps to interpret incidentally identified gene variants related to heart disease

Most athletes with diagnosed and treated genetic heart disease experienced no cardiac events

Ninety-five percent of athletes with a diagnosed and treated genetic heart disease experienced no disease-triggered cardiac events, such as cardiogenic fainting or seizures, implantable cardio-defibrillator (ICD) shocks, sudden cardiac arrest or sudden cardiac death, during an average of seven years of follow up, according to a study being presented at the American College of Cardiology's Annual Scientific Session Together With the World Congress of Cardiology.

About 1 in 5 stroke survivors found to have irregular heart rhythms

Irregular heart rhythms were detected in about 1 in 5 people who survived an ischemic stroke due to atherosclerosis (buildup of fatty substances in the arteries) after being continuously monitored for three years with an insertable cardiac device, according to preliminary late-breaking science presented at the American Stroke Association's International Stroke Conference 2023.

Dual antiplatelet therapy for minor or a warning stroke is underused especially among women

Despite evidence that starting two blood-thinning medications shortly after a minor stroke or a warning stroke (transient ischemic attack - TIA) may prevent a second – possibly more serious – clot-caused stroke within a few months, the treatment regimen is underused especially among women, according to preliminary research to be presented at the American Stroke Association's International Stroke Conference 2023.
