Real-Time Medical Device Telemetry Integration Pipeline

Create a high-performance WebSocket API using FastAPI that can ingest and process real-time telemetry from multiple medical IoT devices simultaneously. Develop a scalable architecture that can handle streaming data from wearable heart monitors, glucose trackers, and respiratory sensors with sub-100ms latency. Implement adaptive rate limiting, device authentication using JWT, and automatic data normalization for different device protocols. Include comprehensive error handling and a background task for persistent storage in a time-series database.
