New method to disrupt spiral waves may be a less painful way to defibrillate hearts

A spiral wave of electrical activity in the heart can cause catastrophic consequences. One spiral wave creates tachycardia -; a heart rate that's too fast -; and multiple spirals cause a state of disorganized contraction known as fibrillation.

Sponge-like solar cells could form the basis for less-invasive pacemakers or similar medical devices

Holes help make sponges and English muffins useful (and, in the case of the latter, delicious). Without holes, they wouldn't be flexible enough to bend into small crevices, or to sop up the perfect amount of jam and butter.

Researchers develop a bioresorbable pacemaker to temporarily monitor and control heart rate

In a proof-of-concept study that aims to address the unmet need for minimally invasive cardiac control and monitoring devices, researchers have developed a network of wireless devices, including a bioresorbable pacemaker, that can temporarily monitor and control heart rate.

Northwestern University scientists unveil a smart, bioresorbable transient pacemaker

Last summer, Northwestern University scientists introduced the first-ever transient pacemaker — a fully implantable, wireless device that harmlessly dissolves in the body after it's no longer needed.

Recommendations to prevent, manage interference in patients with implanted cardiac devices

Recommendations on the prevention and management of interference caused by medical procedures in patients with implanted electronic cardiac devices is published today in EP Europace, a journal of the European Society of Cardiology and presented at EHRA 2022, a scientific congress of the ESC.

Women receive fewer life-saving heart procedures than men

In the first study to examine differences by sex and race in outcomes following the seven most common procedures for heart problems, researchers found that women are less likely to undergo these procedures- and even when women do receive these procedures, they are more likely than men to die while in the hospital, according to data that will be presented at the American College of Cardiology's 71st Annual Scientific Session.

Study reveals how the brain’s blue spot shapes selective attention

How can we shift from a state of inattentiveness to one of highest attention? The locus coeruleus, literally the "blue spot," is a tiny cluster of cells at the base of the brain.

Case report highlights limitations of remote monitoring for early detection of CRM device battery failure

Even after the Food and Drug Administration issued a safety notice and recall, manufacturing defects in certain cardiac rhythm management (CRM) devices led to premature battery depletion that was not picked up by remote monitoring.

Environmental exposure to low-levels of toxic metals may increase risk of clogged arteries

Environmental exposure to low-levels of the toxic metals arsenic, cadmium and titanium appears to increase the risk of plaque buildup in arteries in the neck, heart and legs, according to new research published today in the American Heart Association's journal Arteriosclerosis, Thrombosis and Vascular Biology (ATVB).

Persistent opioid use among 12% of patients after cardiac implantable electronic device procedures

About 12 percent of patients who receive implantable cardiac devices such as a pacemaker or defibrillator and fill an opioid prescription after surgery will consistently use the pain medication in the months afterward, raising the potential for addiction following these common procedures and identifying another pathway that could contribute to the national opioid crisis, according to a new study by researchers at the Perelman School of Medicine at the University of Pennsylvania.
