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.

How persistent AFib impacts TAVR survival

Persistent and paroxysmal atrial fibrillation appear to affect short- and long-term TAVR mortality rates in different ways, according to a new study of nearly 3,000 patients. Some trends fade over time, while others remain in place after many years.

AI-powered platform for arrhythmia detection gains FDA approval

The newly approved DeepRhythm Platform from Medicalgorithmics uses advanced AI to evaluate imaging results and look for signs of cardiac arrhythmias.

Vivek Reddy, MD, Director, Cardiac Arrhythmia Service, and the Leona M. and Harry B. Helmsley Charitable Trust Professor of Medicine in Cardiac Electrophysiology, at Mount Sinai in New York, was involved in most of the late-breaking pulsed field ablation (PFA) trials at the Heart Rhythm Society (HRS) 2024 meeting. He offers an overview of the new data presented and his observations from using PFA. #HRS24 #HRS2024 #PFA #EPeeps

The future of electrophysiology: Reviewing key trends in PFA

Vivek Reddy, MD, was involved in most of the late-breaking pulsed field ablation trials at Heart Rhythm 2024. He spoke to Cardiovascular Business at the conference about those trials and what they mean going forward.
