The Cardiac Mapping ecosystem comprises a structured value chain that transforms raw sensor components into clinically actionable navigation data. Upstream, specialized component suppliers deliver high‑precision electrodes and catheters that form the basis of mapping hardware. Midstream, activities involve device manufacturers, software developers, and system integrators who assemble, certify, and fuse hardware with advanced signal‑processing and 3‑D reconstruction algorithms. Downstream, distributors channel finished systems to hospitals, while clinical service providers install, calibrate, and train electrophysiology teams. End users—cardiology and electrophysiology departments—capture intracardiac signals, generate electro‑anatomical maps, and guide therapeutic interventions. Value is created through the integration of hardware precision, algorithmic insight, and procedural expertise, and captured via equipment sales, service contracts, and data‑driven decision support.
