System to Non-invasively Record Electrocardiograms in Conscious Mice, Rats, and Guinea Pigs
The ECGenie is a non-invasive electrocardiogram recording system. An easy method of recording ECGs in conscious mice. Provides a lead II ECG from the paws. Records the HR, P-R, QRS, QT intervals and shows a power spectral graph.
Applications would include arrhythmia detections, health screenings and drug effects.
The ECGenieTM is the only truly non-invasive instrument for cardiac function in the conscious ambulatory lab animal. One system is capable of measuring ECGs in large quantities of rodents. The operator simply places an animal onto the recording platform, allowing sufficient time for the animals to acclimate, and triggers recording when the paws of the animal are in contact with the electrodes. One technician can record ECGs in approximately 10 subjects each hour. With ease and speed you may be able to non-invasively detect the sought-after cardiovascular phenotype or identify drug-induced arrhythmias in your conscious mice, rats, and guinea pigs.
UNLIKE TELEMETRY DEVICES OR CATHETERS, THE ECGenieTM SYSTEM FOR NON-INVASIVELY RECORDING ECGS IN CONCIOUS RODENTS DOES NOT REQUIRE ANESTHETIC OR SURGERY.
The method and system have now been described in over 15 publications.
