With its modular design, the ecgTUNNEL quickly provides clean and reproducible data.

Clean, reproducible data

The system consists of a base with 4 electrode pads and a restraining tunnel.

Restrained subjects quickly acclimate to their environment, reducing the stress artifact in the ECG. These snapshot recordings (up to a couple hours) are very easy to acquire and reproduce.

Did you know?

Restrained subjects often fall asleep in the tunnel!


Single unit can accommodate multiple sized mouse (15g to 60 g) or rat (up to 800 g) studies.

Combine up to 6-lead ECG with an optional plethysmograph dome for respiratory endpoints with optional exposure and infusion options.

Did you know?

7 different tunnel sizes can adapt on the same base to perfectly fit the subject size.

Easy to use

ecgTUNNEL allows you to avoid complications or adverse side effects encountered with the use of anesthesia, implantation, or at-risk/fragile models, favoring experiments that comply with the 3R’s and IACUC* protocols.

High throughput screening for phenotyping, model development, disease progression, drug effects, etc. allows for efficient and cost–effective assessment of large cohorts.

A single PC can connect 1 to 8 ecgTUNNELs with a simple plug-and-play USB connection.

Did you know?

The methodology used by ecgTUNNEL for more than 10 years, has proved successful and is now used in a variety of applications such as pediatric cardiac research, Emery-Dreifuss muscular dystrophy and more. Learn more

Quick analysis

Acquire and analyze large data files in minutes for heart rate, interval computation and respiratory parameters (rates, durations, breathing depth, degree of bronchoconstriction) or more advanced uses such as arrhythmia detection and heart rate variability (HRV). 

Learn from our researchers

Kimberly Londer BS works at the BioMET Center, in the University of Maryland.

She is multi-focal and works with the orthopedic department and as a cardiac research assistant. She is using ecgTUNNEL to capture ECG on young mice, without anesthesia.

We are pleased to share an interview with Kimberly, who kindly shared her thoughts about her research with us.
