Benefits

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!

Modular

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

Acquire and analyze large data ECG and respiratory dataset in just minutes.

The ecgAVG module provides rapid access to average ECG beats, while advanced algorithms support respiratory parameters (rates, durations, breathing depth, degree of bronchoconstriction), arrhythmia detection and heart rate variability (HRV) assessment.

ecgTUNNEL simplifies cardiovascular and respiratory monitoring by eliminating the need for anesthesia and surgical implantation. This reduces stress on animals, minimizes risks in fragile disease models, and supports study designs aligned with the 3Rs principles and IACUC* guidelines.

Designed for high-throughput screening, ecgTUNNEL enables fast, cost-effective evaluation of large cohorts for phenotyping, disease progression, model characterization, and drug effect assessment.

Setup is effortless: a single PC can connect and manage up to eight ecgTUNNEL systems simultaneously through a simple plug-and-play USB connection, allowing users to start acquiring data within minutes.
