From atrial fibrillation to sudden cardiac death, arrhythmias remain a major contributor to morbidity. At WCC 2026, this session will cover diagnostics, risk stratification, and rhythm management strategies. Key themes include catheter ablation, device therapy (ICDs, CRT), wearable monitors, and anti-arrhythmic drug advances. The session will also highlight innovations in EP mapping systems, AI-assisted arrhythmia detection, and managing arrhythmias in special populations such as athletes and the elderly.
