ecgTUNNEL is a plug-and-play system for snapshot ECG* recordings and respiration data in rodents that eliminates the need for surgery and anesthesia.
It combines up to 6-lead ECG with an optional plethysmograph dome for respiratory endpoints with optional exposure and infusion options.
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, or when subjects are particularly fragile and cannot tolerate surgery or anesthesia.
In an interview, Kimberly Londer BS, from the University of Maryland, said, “there are few systems, publications, or data that exists on small animal ECG without the use of anesthesia or telemetry.” Using ecgAUTO, she “scan[s] an entire recording for AF, ventricular disorders and other arrhythmias of interest within seconds.”

The basic system consists of:
To perform respiration measurement by plethysmography, the following hardware is added to the basic system:
| Specifications | Mouse | Rat | Subject weight | 15-60 g | 300-1100 g |
|---|---|---|
| Restrainer diameters | 20, 25, 32, 40 mm | 50, 60, 70, 80 mm |
| Restrainer length | 120 mm | 270 mm |
