Study Shows Medtronic ICM Accurately Predicts Risk Thresholds for AFib Patients Using AI

DAIC

16, 2025 Primary results from the DEFINE AFib clinical study show the Medtronic LINQ family of insertable cardiac monitors (ICM), paired with a novel algorithm, were able to detect atrial fibrillation episodes and properly risk stratify patients as high risk prior to an AF-related healthcare utilization 80% of the time. Piccini, M.D.,

Higher AFib Procedure Volumes Associated With Increased Procedural Success, Lower MAE Rates

American College of Cardiology

Higher hospital and physician atrial fibrillation (AFib) ablation procedure volumes were associated with increased acute procedural success and lower rates of major adverse events (MAEs), according to a study published in Heart Rhythm.

HRS 2024: Innovation Meets Reality

DAIC

In electrophysiology, innovation is king, but it is often incremental, and it almost always lacks rationale, comprehensive clinical documentation and relevance for hospitals that try to balance the increasing costs of new technology with increasing demand and reimbursement that just can’t keep pace.

Biosense Webster Study Supports Low and Zero Fluoroscopy Workflow as Safe, Effective Alternative to Conventional Catheter Ablation

DAIC

The results support the use of workflows to reduce radiation exposure during catheter ablation for the treatment of paroxysmal atrial fibrillation (AFib) while maintaining safety, efficacy, and long-term patient outcomes comparable to traditional procedures.1 1 These included one pseudoaneurysm, one PV stenosis and one hematoma.1

Wide Complex Tachycardia -- VT, SVT, or A Fib with RVR? If SVT, is it AVNRT or AVRT?

Dr. Smith's ECG Blog

He was noted to have irregular heart rhythm with rates 120-170s. I don’t see evidence of retrograde atrial activity during the WCT — but usually with the “almost regular AFib rhythms” — you can when you measure pick up some slight differences — so my hunch is that the initial ECG is a REENTRY SVT rhythm, that then breaks down to AFib.

What Happens During Electrical Cardioversion?

AMS Cardiology

Cardioversion is used to correct abnormal heart rhythms, also known as arrhythmias. When your heart beats too quickly, too slow, or irregularly, it can affect your blood flow and lead to severe complications like stroke or heart failure. Cardioversions can help “reset” your heart rhythm to its regular pattern.
