Cardiopulmonary Exercise Testing–Guided Optimization of Pacemaker Rate-Response in an Endurance Athlete With Sinus Node Dysfunction
Highly active patients with sinus node dysfunction depend on rate-response pacing during exercise. Optimized pacemaker function for high intensity sports can relieve symptoms and improve performance. Our case highlights the importance of an athlete-tailored approach combining maximum effort metabolic, exercise, and device testing.
