Non-invasive ECG & respiration for rodents

ecgTUNNEL records up to 6-lead ECG signal in a few seconds with 4 electrode pads, with respiration in option. Mouse and rat models, with interchangeable tunnels, are available, to accommodate from neonate to adult subjects.

This set up is particularly useful for snapshot recordings during sessions lasting a few minutes. It is often used for longitudinal studies where the subjects are studied on successive experiment days.

Standard ECG interval can be quickly recorded, for a simple heart rate monitoring. In-depth cardiovascular function can also be explored. Main applications cover:

  • Toxicology studies
  • Early safety
  • Aging
  • Cardiac monitoring for animal well-being, pain, stress or behavior
  • Screening
  • Cardiovascular diseases, such as cardiac dystrophy or some arrhythmias (conduction problem, Ion channels …)





Quick & easy setup




System configuration
  • Tunnel gently and firmly restrains the subject
  • 4 electrode pads record up to 6-lead ECG
  • Integrated amplifier
  • Direct USB link to computer

For respiratory studies, this setup must be completed with:

  • A respiratory dome, with a pneumotachograph and a pressure port
  • A bias flow pump for air renewal
  • A differential air pressure transducer
Data analysis

Acquisition and real-time analysis are perfomed in iox2 software, from up to 8 ecgTUNNELS simultaneously and provide:

  • Basic heart rate analysis
  • Respiratory rates and durations, breathing depth
  • Degree of bronchoconstriction (penH)

Post-acquisition ECG analysis, based on shape recognition technique, is done in ecgAUTO software:

  • Beat-by-beat or average beat analysis
  • Single or multilead
