Electrophysiology

The cardiac subspecialty of electrophysiology (EP) diagnoses and treats arrhythmias. This includes use of pacemakers to treat bradycardia, implantable cardioverter defibrillators (ICD) for tachycardia, heart failure and patients at risk of sudden cardiac arrest, and cardiac ablation treatments to treat heart rhythm disorders.

PFA takes center stage at Heart Rhythm 2025 as medtech companies share new data

Pulsed field ablation was one of the biggest topics at Heart Rhythm 2025, the annual meeting of the Heart Rhythm Society. Medtronic, Johnson & Johnson MedTech, Boston Scientific, Abbott, Kardium and Field Medical all shared new data at the conference highlighting the safety and effectiveness of their advanced PFA technologies.

Medtronic receives FDA approval for smallest defibrillation lead of its kind

Medtronic emphasized that this device should be especially valuable when treating younger patients or those with a small anatomy.

Alexander Kolomaya, MD, a cardiology resident at the University of Utah, presented a study on U.S. national trends in left atrial appendage occlusion (LAAO) volume and open payments from vendors to operators at the American Heart Association 2024 meeting.

Vendor payments not responsible for rising popularity of LAAO procedures

Consulting fees and other vendor payments do not appear to be directly influencing U.S. physicians to implant more Watchman devices. Researcher Alexander Kolomaya, MD, discussed his team's findings on this topic.

Same-day discharge after cardiac ablation: Cardiologists share recommendations

Same-day discharge won't always be a great fit after cardiac ablation, of course, but it has been associated with considerable patient satisfaction as well as improved efficiency and substantial cost savings. The Heart Rhythm Society and American College of Cardiology have shared a new scientific statement on the subject.

Atrial Fibrillation Centers of Excellence: The best path forward for high-quality care and better outcomes

The world is in the throes of an AFib pandemic, one that could potentially get worse in the years ahead due to population growth, economic hardships and rigid resource limitations. According to the Heart Rhythm Society, one way to effectively combat this issue is the development of more AFib Centers of Excellence.

Cardiologists make history, perform world’s first ventricular ablation guided by real-time MRI

“MRI images provide a better view of the anatomy of the heart and the instruments used for treatment, but also of the changes made to the treated cardiac tissue,” one cardiologist explained. “Unlike X-ray images, the entire area surrounding the heart can be seen, including the blood vessels and valves."
