"content": "Macro drivers include aging demographics, rising atrial fibrillation prevalence, and value-based reimbursement shifting preference toward MRI-conditional and leadless pacemakers; meanwhile, FDA/EMA post-market surveillance and tightening hospital budgets intensify cost-of-ownership scrutiny. Competitive intensity is rising as Medtronic, Abbott, and Biotronik accelerate R&D in battery-free, self-charging units while contract manufacturers diversify supply chains to reduce single-source component risk. North America remains the largest regional market, accounting for ~40% share, but Asia-Pacific is the fastest-growing region at a projected 7% CAGR as China and India scale implant volumes."
