Heart Rhythm

Hearts should have normal rhythm to their beats, but when these beats are out of synch, it causes inefficient pumping of blood. Irregular heart arrhythmias occur when the electrical signals that coordinate the heart's beats do not work properly. This can cause beats that are too fast (tachycardia), or too slow (bradycardia). Tachycardias include atrial fibrillation (AFib), supraventricular tachycardia, ventricular fibrillation, and ventricular tachycardia (VT). Bradycardias include sick sinus syndrome and conduction block. Electrophysiology arrhythmia treatments include medications, life style changes, and the EP lab interventions of catheter ablation, and implantable pacemakers or defibrillators.

New-onset AFib, linked to worse outcomes and higher healthcare costs, seen in 3.5% of TEER patients

Patients who developed new-onset AFib tended to be sicker than those who did not.

Researchers awarded $37M to see if Apple Watch can lower stroke risk among AFib patients

Could wearables help AFib patients take fewer blood-thinning medications and reduce their risk of stroke? The team behind a new seven-year analysis hopes to find out. 

Dhanunjaya "DJ" Lakkireddy, MD, executive medical director for the Kansas City Heart Rhythm Institute at HCA Midwest Health, professor of medicine at the University of Missouri, Columbia, deputy editor for the the Journal of Atrial Fibrillation, and serves on the HRS Board of Trustees and section steering committee chair for the ACC, explains the potentially devastating impact of Medicare cuts on electrophysiology (EP) and patient care.

"By imposing a 35%-42% cut, [CMS] has essentially created a scenario where it is going to destroy electrophysiology as a field," explained Dhanunjaya "DJ" Lakkireddy, MD.

AI model uses ECG data to identify new cases of AFib

“Our ultimate goal is to prevent strokes," one Mayo Clinic electrophysiologist said. "I believe the current study has brought us one step closer.”

Drinking coffee linked to a much lower risk of heart disease, death

"Our findings indicate that drinking modest amounts of coffee of all types should not be discouraged but can be enjoyed as a heart-healthy behavior," said a cardiologist involved in the study. 

The U.S. Food and Drug Administration (FDA) has granted the first pediatric indication for use for an implantable cardiac monitor to Medtronic. The Linq II Insertable Cardiac Monitor (ICM) system is the first such device receive 510(k) clearance for use in pediatric patients over the age of 2 who have heart rhythm abnormalities and require long-term, continuous monitoring.

FDA grants new pediatric indication for Medtronic Linq II implantable cardiac monitor 

The FDA granted the first pediatric indication for an implantable cardiac monitor. The Linq II can be used in pediatric patients over the age of 2 for up to 4.5 years of long-term, continuous monitoring.
