Tempus ECG-AF Algorithm: Enhancing Early Detection of Atrial Fibrillation

We have written previously on this blog about the difficulty with atrial fibrillation (AF) screening - primarily because of a lack of cost-effective measures, screening is currently not recommended by the USPSTF. In this setting, a 2019 ground breaking study from the Mayo Clinic showed that artificial intelligence (AI) can make accurate predictions about the presence atrial … Continue reading Tempus ECG-AF Algorithm: Enhancing Early Detection of Atrial Fibrillation →

AI-Guided Catheter Ablation for Persistent Atrial Fibrillation: A Game-Changer?

Atrial fibrillation (AF) is the most common sustained cardiac arrhythmia, affecting millions worldwide. While pulmonary vein isolation (PVI) has been the cornerstone of catheter ablation for AF, its long-term success remains limited, particularly in patients with persistent or long-standing persistent AF. Many patients experience recurrence, often due to non-PV triggers and underlying arrhythmogenic substrates that … Continue reading AI-Guided Catheter Ablation for Persistent Atrial Fibrillation: A Game-Changer? →
