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.

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.
AI helps cardiologists terminate AFib for good with ablation
Advanced AI can provide real-time feedback to cardiologists, helping them deliver high-quality care.
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.
PFA startup founded by industry veteran to share first-in-human data at Heart Rhythm 2025
Field Medical, founded in 2022 by Steven Mickelsen, MD, is set to make a significant splash at the Heart Rhythm Society's annual meeting in San Diego. The company also just raised $40 million in financing.
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.

New data published in Nature Communications may explain why heart problems are so common among shift workers.

CIED research highlights the close relationship between AFib and ischemic stroke

AFib episodes that last 5.5 hours or longer increase a patient’s risk of ischemic stroke by a significant margin.

AFib patients with COPD face worse outcomes

Researchers recommend a more comprehensive evaluation of respiratory function in AFib patients.

Heart rhythm specialists awarded $3M to develop new AFib therapy
