Many of our customers had expressed their desire for a device to non-invasively measure ecg from conscious mice and rats, in order to automate the acquisition process on a large number of subjects.

In response, we designed, developed, extensively tested and launched the ecgTUNNEL to allow you to obtain high-quality and noise-free ecg signals from conscious non-anesthetized mice or rats.

The tunnel of ecgTUNNEL restrains the subject firmly and gently, without causing trauma.  For each model (mouse or rat), we propose a range of (interchangeable) tunnels to accommodate newborn to adult subjects.

The four electrode pads on the base of the ecgTUNNEL allow you to obtain 1- to 6-lead ecg data.  

The key advantages of this method - no surgery, no anesthetic, quick and easy setup, short adaptation time - can help you increase productivity particularly when screening subjects to be further investigated.

The following article by a research team (INSERM U582 - Institut de Myologie, Groupe Hospitalier Pitié-Salpêtrière) gives a valuable overview of the ecgTUNNEL from the researcher's point of view:

In their discussion, the workers state "when compared to telemetry, this restrained ecg monitoring method shows a very good yield".
