The Nihon Kohden Cardiolife TEC-5631 is a professional multi-parameter biphasic monitor and defibrillator designed for emergency cardiac care, resuscitation, and critical-care applications. It combines ActiBiphasic defibrillation, ECG monitoring, synchronized cardioversion, AED functionality, and built-in non-invasive external cardiac pacing in a portable system.
The TEC-5631 supports demand and fixed transthoracic pacing, making it suitable for situations where temporary external cardiac pacing is required. Its Smart Cable technology also allows selected configurations to support SpO₂, EtCO₂ and NIBP monitoring.

Built-In Non-Invasive Pacing
One of the key features of the TEC-5631 is its built-in external pacing capability.
It provides:
- Demand pacing
- Fixed pacing
- Transthoracic cardiac pacing
- Quick access to pacing functionality for emergency care
This allows the device to provide temporary non-invasive pacing when clinically indicated.
ECG Monitoring & VF Analysis
The TEC-5631 provides 3-lead or 6-lead ECG monitoring.
It also supports continuous ventricular fibrillation (VF) analysis, including during:
- CPR
- Charging
- Emergency resuscitation workflows
The device incorporates ec1 arrhythmia analysis for advanced ECG rhythm assessment.
AED & Synchronized Cardioversion
The Cardiolife TEC-5631 provides both:
Semi-Automatic AED Mode
The AED function supports semi-automatic external defibrillation during cardiac emergencies.
Synchronized Cardioversion
The device also supports synchronized cardioversion for appropriately indicated cardiac rhythms.
Multi-Parameter Monitoring
Through Nihon Kohden's Smart Cable technology, selected configurations can support additional monitoring parameters.
