seca CT331 Wireless PC ECG Machine – 12‑Lead USB/Bluetooth with EMR Connectivity
The seca CT331 is a next-generation, PC-based interpretive 12‑lead ECG system that offers both USB and secure medical Bluetooth connectivity, allowing wireless ECG data transfer and flexible clinical deployment. Its lightweight, splash-resistant housing is designed to resist impact and is easy to disinfect—ideal for large clinics, hospital wards, and mobile settings
Recording at up to 32 kHz sampling per lead, the CT331 captures high-fidelity waveforms and supports advanced True Wave® filter and digital pacemaker detection, preserving signal integrity for precise analysis. LED indicators guide electrode placement and show device status for optimal acquisition.
Powered by a rechargeable integrated lithium battery offering up to 12 hours runtime, the CT331 supports continuous clinical use—and can be easily recharged via USB
It includes seca cardio ECG software with auto-interpretation, multi-format PDF report generation (e.g. 4×3 lead format), single-beat and cumulative complex analysis, rhythm strips, and QTC interval—a clinical essential for mental health and critical care settings
Designed for seamless integration, the CT331 connects to EMIS, SystmOne, Medicus, and other EMR systems (Vision). USB data export simplifies paperless workflows and allows automatic PDF report transfer—though EMIS integration may require a license
- Compatible with all leading EMR systems e.g., emis, vision, isoft and others
- Fully integrates with SystmOne
- Innovative medical Bluetooth Technology removing the need for a USB cable connection, allowing greater flexibility in large clinic rooms
- seca cardio ECG software functions: single beat analysis, cumulative complexes, measurement table/interpretation/worklist of ECG reports automatically generated once recorded offering improved work process/single patient database viewed throughout practice network
- High quality recordings of all twelve leads with a sampling rate of up to 4000 Hz. Clearly arranged choice of A4 reports with one click including the popular 4 x 3 with lead II rhythm strip
- QTC interval – Ideal for Mental Health
- Impedance measurement: all electrodes highlighted with automatic quality indication to ensure the perfect ECG
- Digital pacemaker detection - Robust defibrillator proof unit
