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 electrical test to screen individuals at risk of sudden cardiac arrest

New research from the Victor Chang Cardiac Research Institute will allow families around the world to discover if they are carrying genetic mutations that cause sudden cardiac arrest – a condition that kills nine out of 10 victims.

New therapeutic approach for cardiac repair after a heart attack

Following a heart attack, the human body is incapable of repairing lost tissue due to the heart's inability to generate new muscle.

Implantable heart rhythm monitor does not benefit NSTEMI patients

Patients who received an implantable heart rhythm monitor after suffering a heart attack did not have fewer subsequent cardiovascular events overall, but a subset of patients whose heart attack was classified as non-ST segment elevation myocardial infarction (NSTEMI) did see strong benefits, in a study presented at the American College of Cardiology's 71st Annual Scientific Session.

ECG can pinpoint hospitalized COVID-19 patients at high risk of mortality

A simple electrocardiogram (ECG) can pinpoint hospitalized COVID-19 patients at high risk of death who might need intensive management. That's the finding of a study presented at EHRA 2022, a scientific congress of the European Society of Cardiology.

'Stroke-heart syndrome' may put stroke survivors at higher risk for future cardiovascular events

People who survive an ischemic stroke are much more likely to develop major heart complications during the first month after their stroke, and, as a result, they also have an increased risk of death, heart attack or another stroke within five years, compared to people who don't develop heart problems soon after a stroke, according to new research published today in Stroke, the peer-reviewed, flagship journal of the American Stroke Association, a division of the American Heart Association.

Daily coffee intake associated with benefits to heart health

Drinking coffee - particularly two to three cups a day - is not only associated with a lower risk of heart disease and dangerous heart rhythms but also with living longer, according to studies being presented at the American College of Cardiology's 71st Annual Scientific Session.
