Electrocardiography (ECG) is the "gold standard" using either hard wire or telemetry transmission in determining in vivo cardiac functions. In ECG monitoring, the QT interval, a measure of time from the start of the Q wave to the end of the T wave, represents the electrical depolarization and repolarization of the ventricles. QT prolongation implies a delayed ventricular repolarization which may cause ventricular tachyarrhythmias and possibly sudden death.

Here in Creative Bioarray we use a non-invasive telemetry system with ECG Transmitter. This amplifies and transmits high-fidelity ECG data. Implants are small enough to be implanted into mice as young as P18. With the implanted animal inside of the cage, data can be recorded by simply placing the animal’s cage on top of the receiver tray. ECG data from the sensor is telemetered to the receiving tray and then sent to the data acquisition system. Automated ECG analysis can quickly score multiple channels of ECG data simultaneously.
