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.

FDA approves trial for new type of thermal-ablation system to treat ventricular arrhythmias

The FDA has approved a clinical trial to evaluate the safety and efficacy of a new type of ablation catheter for patients with ventricular tachycardia (VT) resistant to conventional anti-arrhythmic drugs or standard ablation procedures.

New expert guidelines highlight the importance of quickly diagnosing and treating CIED infections

Though removal of the affected CIED is typically the smartest treatment option—and one supported by specialty groups all over the world—a majority of patients keep living with the device, often resulting in hospitalization or even death.

Affera Inc Medtronic $925 million catheter ablation atrial fibrillation (AFib)

Medtronic completes acquisition of heart rhythm tech company in a deal reportedly worth $925M

Affera’s portfolio includes interventional solutions such as the Affera Prism-1 mapping and navigation platform, designed to help electrophysiologists diagnose heart rhythm issues, and the Sphere-9 cardiac ablation catheter.

Rethinking arrhythmias: Women may face a higher AFib risk than men

New research, published in JAMA Cardiology, challenges the common belief that AFib is more likely to develop among men than women. The key problem, it seems, is that prior research teams did not understand the significance of certain risk factors.

Medtronic EV ICD clinical trial safety endpoints ESC Congress 2022

Medtronic’s first-of-its-kind ICD meets safety endpoints in global clinical trial

The promising results were presented at ESC Congress 2022 and published in the New England Journal of Medicine. Medtronic's new-look device is not yet approved for sale or distribution. 

ESC Congress 2022 European Society of Cardiology

6 key sessions from ESC Congress 2022: TAVR mortality, AI vs. sonographers, radial vs. femoral access and more

ESC Congress 2022, the annual meeting of the European Society of Cardiology, was jam-packed with eye-opening new research from many of the leading voices in cardiovascular and vascular medicine. These six sessions were just some of the weekend's many highlights.

Very low doses of edoxaban are safe and effective for frail, elderly AFib patients

Elderly patients are often not eligible for oral anticoagulant therapy due to the risk of bleeding events or other adverse outcomes. A very low dose of edoxaban, however, appears to be a safe treatment option, even for especially frail patients.
