The CARDIOLINE® ar2100adv is a multichannel electrocardiograph designed for optimized performance in ECG recording, offering reliability, modularity, versatility, and upgradeability. It features a dual power supply system, operating on both mains electricity and rechargeable internal batteries.
Function Description:
The ar2100adv is capable of recording ECG exams in automatic, manual, and timed modes. It reproduces ECG signals on 210 mm paper using a high-resolution thermal printer, supporting various formats including 3, 6x1, 6x2, "Full Page 1" (3x4+R for 1 page), "Full Page 3" (3x4+3R for 1 page), and 12 channels. The device can store the most recent recording in automatic mode and print additional copies.
Through its flexible software and infrared interface, the ar2100adv can be customized with various "options" at any time. These options include:
- Memory option: Stores up to 40 full ECG exams, enabling a "paper saving" mode where immediate printout is not required.
- ECG parameters option: Provides an automatic ECG parameter measurement program.
- ECG signal interpretive option: Offers a diagnostic support program for ECG signal interpretation.
- Arrhythmia option: Detects arrhythmia events during continuous recording.
- HRV analysis option: Detects variations in heart rate.
- PC archive option: Allows saving exams to an archive on a personal computer running CARDIOLINE software via a wireless IR interface, eliminating the need for a direct PC connection.
- PC-ECG option: Enables real-time display of all twelve leads on a computer screen, facilitating patient medical record management and digital archiving of exams using CARDIOLINE software. This option also includes an optional module for automatic ECG signal interpretation.
