The BT3/6 (3/6-lead) and BT12 (12-lead), hereafter referred to as the "BT devices", are battery powered devices capable of acquiring and transmitting a standard electrocardiogram (EKG) to be applied by medically trained persons for the purpose of cardiac monitoring and diagnosis performed by medical professionals. The collected data is not interpreted by the BT device as this is done by the monitoring device operated by medical professionals. The collected data is processed by the BT device and then transmitted via a standard wireless link to a monitoring device, such as a PC or hand-held device for display, review, printing, saving and post event processing by medical professionals. Use of the BT devices is not restricted to adult population, but is also intended for infants weighing less than 10 kg (22 lbs.).

Measurements taken by the BT devices are only significant if considered in connection with other clinical findings. No therapy or drugs can be administered based solely on ECG data derived from the BT devices. The BT devices are not intended for monitoring critical patients and are not intended for intracardial use.

Indications for use as stated in the FDA summary.
