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.

Champagne could be good for the heart—and other lessons from a new risk analysis

Researchers explored the potential impact of more than 100 risk factors on a person's risk of sudden cardiac arrest. Some of their findings were what you may expect, but others were much more surprising.

Bayer's finerenone reduces risk of AFib, atrial flutter in all CKM syndrome patients

New data published in JACC represents another big win for Bayer's finerenone. The drug has previously been linked to cardiovascular benefits for patients with CKD and heart failure, but its potential across the full CKM spectrum remained a bit of a mystery.

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.
