In this December 2025 Issue 3 of EP-Edge Journal Watch , Dr. Niraj Sharma, cardiologist and cardiac electrophysiologist, breaks down the strongest evidence to date on smartwatch AFib detection , Apple Watch ECG performance , false alerts , AF burden tracking , and post-ablation monitoring . With more than 450 million global smartwatch users and growing, both clinicians and patients rely on devices like the Apple Watch , Fitbit , Samsung Galaxy Watch , and Withings for early arrhythmia detection. This episode answers the questions everyone is asking: What You’ll Learn in This Episode • How accurate are smartwatches for detecting atrial fibrillation (AFib)? A breakdown of major meta-analyses across Apple Watch ECG, PPG sensors, and multi-device comparisons — including real numbers on sensitivity, specificity, and real-world diagnostic performance. • Why do so many smartwatch alerts end up being false positives? Dr. Sharma explains the positive predictive value problem in low-prevalence populations and why young, healthy users often receive incorrect AFib notifications. • Apple Watch ECG vs. Holter monitor vs. implantable monitor Find out when a smartwatch is good enough, when a clinical monitor is necessary, and when an implantable cardiac monitor (ICM) remains the gold standard. • Can smartwatches reliably detect AFib recurrence after ablation? Review of the CIRCADOSE data showing smartwatch AFib-burden algorithms compared with implantable monitors — and when they outperform intermittent Holters. • Why EP patients get so many inconclusive smartwatch readings Including pacing, left bundle branch block, low-voltage signals, and ectopy —…","meta_description":"Smartwatches are now among the most widely used heart-monitoring tools in the world — but how accurate are they really at detecting AFib?
