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.

Abbott PFA system gains FDA approval
The Volt Pulsed Field Ablation System from Abbott has been approved by the FDA. The technology, which gained CE mark approval in March, features a one-of-a-kind catheter design and allows patients to be treated under conscious sedation.
New PFA registry will use AI, EHR integration to gather real-world data
PFA has emerged as the preferred ablation strategy for many electrophysiologists, but some questions do remain about its long-term impact. HRS is developing this new registry to be as user-friendly for clinicians as possible.
FDA approves new nasal spray for patients with abnormal heart rhythms
Milestone Pharmaceuticals will be selling etripamil under the brand name Cardamyst. It is expected to hit the U.S. market in early 2026.
FDA clears next-generation cardiac mapping software
San Diego-based Vektor Medical first secured FDA clearance for the AI-powered technology back in 2021. This updated announcement covers the latest version, which includes atrial flutter mapping and several other new features.
Q&A: Cardiologist reviews key trends in pediatric electrophysiology for 2026 and beyond
Pediatric electrophysiology is an invaluable part of any healthcare system, and its importance is only growing as technologies continue to evolve. We spoke to Nicholas Von Bergen, MD, to learn more about where the specialty is headed in the years ahead.

Diabetes associated with much higher risk of sudden cardiac death

According to a new study of nearly 7,000 patients, type 1 and type 2 diabetes are both linked to significantly shorter life expectancies. The risk of sudden cardiac death appears to be highest for younger patients.

FDA clears new left-heart access system from Atraverse Medical

The Hotwire Transseptal Access System includes the Hotwire RF Generator and Hotwire RF Guidewire, giving electrophysiologists the tools they need for left-heart access.

Cardiology groups share new recommendations for performing safe, effective cardiac ablations in ASCs

The timing of this new guidance from the Heart Rhythm Society and American College of Cardiology could not have been better—the document went live just as CMS finalized its decision to cover cardiac ablation procedures performed in ASCs.
