Awake Lab Animal ECG Clinic System
The ECGenie Clinic is a rapid non-invasive solution for recording electrocardiograms (ECGs) in awake mice, rats, and guinea pigs. Applications include arrhythmia detection, health monitoring, and drug screening in fragile transgenic and knockout animals, including newborn pups.
ECGenie Clinic records the cardiac electrical signals at 2 kHz to provide optimal fidelity in describing the rapid ECG interval durations in mice (e.g., a QRS interval duration of ~8 ms). The typical laboratory setting easily accommodates the footprint of the entire system. This includes the disposable electrode recording towers, analog input and bioamplification, and direct connection to Windows computers.
The instrument is based on patented technology for non-invasively detecting cardiac electrical activity through the animals’ paws. The size and spacing of the conductive surface facilitates contact between the electrodes and the paws to provide a lead II ECG in laboratory animals. EzCG analyses software, provided by Mouse Specifics, analyzes the signals to assess animal health, cardiac diseases, and drug toxicity.
