The PageWriter XLi is the flagship of the PageWriter series. This interpretive, real-time cardiograph delivers a comprehensive array of powerful innovations to help you read, analyze, transmit, store, report on, and share ECG information. All ECGs are of the highest quality, thanks to AC noise filtering and baseline wander correction. And all traces are printed on a continuous-feed, digital-array printer for crisp, easy-to-read ECGs on standard page sizes. So there's no cutting or pasting. Plus, records are clearly labeled with ECG data and patient information, as well as automatic measurement and analysis for adult and pediatric patients alike. The PageWriter XLi comes with Philips' predictive instruments, ACI-TIPI and TPI, and it's the only cardiograph in the industry to offer a full, lifetime warranty on the digital patient acquisition module.
