Living near an airport may make for a quick commute when getting out of town, but that convenience may come at a cost. New research suggests such an environment, with long-term exposure to aircraft noise throughout the day, may increase risk of…

In recent years, automated external defibrillators (AEDs) have become more common in public spaces such as movie theaters, shopping malls and restaurants. But survival rates for out-of-hospital cardiac arrest remain between 8 and 10 percent.

Researchers from Rice University and the Texas Heart Institute are introducing a wireless pacemaker that can be implanted directly into a patient’s heart at this week's IEEE’s International Microwave Symposium in Honolulu, running through June 9…

A new study by researchers at the University of Pennsylvania produced evidence that shows men’s lower resting heart rate could contribute to why they commit crimes at a higher rate.

There’s nothing wrong with indulging in chocolate regularly—at least when it comes to your heart, according to a new study.

The research, published online in the journal Heart, revealed that regular chocolate consumption may be…

When it comes to heart problems, one go-to piece of advice for overweight patients was to lose weight. But cardiologists may have to look more deeply into the correlation between obesity and atrial fibrillation.

Apple devices just keep getting smarter. New research presented at this year’s Heart Rhythm Society (HRS) conference in Chicago showed that when paired with an artificial intelligence-based algorithm, the watch can detect atrial fibrillation (…

Though physicians typically use adenosine, calcium channel blockers or beta-blockers in patients suffering from paroxysmal supraventricular tachycardia (PSVT), new research has given evidence that a simple, self-use nasal spray could be effective…

The Heart Rhythm Society (HRS) recently announced the late-breaking clinical trials sessions for the upcoming Heart Rhythm scientific sessions.

The 38th annual conference takes place from May 10 to May 13 at McCormick Place in Chicago.…

An analysis conducted at the Munich Octoberfest found that acute alcohol consumption was associated with sinus tachycardia and other cardiac arrhythmias.

Lead researcher Stefan Brunner, MD, of University Hospital Munich in Germany, and…

The need for permanent pacemakers in patients with severe aortic stenosis who undergo transcatheter aortic valve replacement (TAVR) remains a complication, even as TAVR expands into lower-risk groups. That may prove to be a limitation, especially…

After adjusting for sociodemographics, health behaviors and clinical characteristics, patients with atrial fibrillation who had low health literacy were less likely to be aware of their diagnosis, according to an analysis of members from two…

A meta-analysis of four randomized trials found that using primary prevention implantable cardioverter defibrillators (ICDs) decreased all-cause mortality by 25 percent in patients with nonischemic cardiomyopathy.

Lead researcher Sana M. Al…

Although research has shown automated external defibrillators (AEDs) can increase survival after cardiac arrest, only 17 of 50 U.S. states required at least some of their schools install AEDs as of February 2016, according to a database analysis…
