Intended Use

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 handheld 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. BT devices are not intended for monitoring critical patients and are not intended for intracardial use. Federal law restricts this device to sale by or on the order of a physician.

KG | K082077 | | | 3/6 | ## 5.9 Device Description BT3/6. BT12 is a compact ECG device which is worn on the body and is capable of wireless data transmission. With the BT3/6 type, 2 ECG leads (II - III according to Einthoven) can be measured via a 4-pin cable. The receiving unit can calculate four additional leads (lead I according to Einthoven, aVL, aVR, aVF according to Goldberger).Type BT12 has a 10-pin cable, which, in addition to the leads of the BT3/6 variant, can also measure the 6 leads according to Wilson. With this cable, one can select among 3-, 6- or 12-channel ECG measurements. The cables of the BT are pluggable and therefore can be easily changed. The electrode clips on the patient cables are suitable for connection to button and tab electrodes. It has an integrated electrode contact detector and a heart rate meter, the results of which are displayed on an integrated LCD display. Thanks to the integrated radio data transmission technology, BT3/6, BT12 is able to transmit ECG data online over a range of up to 10 m to a monitor or recording unit for further evaluation. BT3/6, BT12 can be used in all medical applications where the long, stiff trunk cables are a problem due to their weight, their motion artifacts or their electromagnetic susceptibility or because they limit the patient in his freedom of motion. Especially significant are the applications in which it is necessary for the patient to move around freely, for example when the patient is undergoing a stress electrocardiogram. BT3/6, BT12 is compact and simple to operate. A clip allows the device to the patient's clothing. BT3/6, BT12 is powered by two standard AA cells. Patient contacting components are the electrodes. BT3/6, BT12 is intended for use with approved. biocompatible electrodes only. A user manual with detailed description of the device is submitted in section 13 "Proposed Labeling". ## 5.10 Intended Use Statement 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.

Note in manual that guarantee of defibrillation protection can be given only in combination with original cable | The CG-7000DX-BT is not a defibrillation-proof device (optional cable available for defibrillation proof use). | Both devices are intended for continuous wireless transmission of ECG signals and both are portable due to battery-supply and light weight. Both devices are capable of acquiring the ECGs at remote sites and transmitting them via radio transmission to an appropriate receiving station. Therefore, the device under consideration and the predicate device are very similar in their basic functions. The predicate device claims conformance with the ECG standards ANSI/AAMI EC11:1991, and ANSI/AAMI EC38:1998. BT3/6, BT12 is conform with hardware requirements of EC11 and EC38. Exception is the offset-voltage requirement of ±300mV. With BT3/6, BT12 an offset of up to ±190mV does not influence the baseline of the ECG signal. But performance is better than that of the predicate device which states DC offset of only ±75 mV. The differences in technological characteristics between BT3/6, BT12 and the predicate device can be summarized as follows: {5}------------------------------------------------ The resolution of the BT devices is higher than that of the predicate (15 bit compared to 10 bit) which results in a better ECG signal quality. The predicate device is available only for the acquisition of 12-lead ECGs, whereas the device under consideration is available for measuring either a 12- or a 3/6-lead ECG (BT12 and BT3/6). CMRR of the BT devices is higher than with the predicate (>94 db compared to 60 db). This results in a better ECG signal quality in the presence of interference signals. Input impedance is specified higher with the BT devices (20 MΩ compared to >10 MΩ). Therefore, ECG signal quality is less dependent on electrode contact quality with the BT as with the predicate. The two devices differ in their data storage functionality. The BT stores data only when the wireless radio connection is interrupted, e.g. when the patient leaves the transmission range. After the connection is re-established the stored data is transmitted to the receiving unit. Interruption of the transmission is indicated on the device. The BT devices are not intended for use as Holter monitors. The CG-7000X-BT has a limited event storage capability of up to 40 ECG recordings. The BT devices and the predicate are capable of continuously transmitting ECG data. The graphic display of the CG-7000DX-BT is able to display the measured ECG, while the BT devices can display the ECG on the receiving unit only. But, the predicate is of low resolution and should not be used to make a diagnosis. The BT devices have a higher degree of protection against penetration of water (IPX3). ## 5.13 Summary of Device Testing The BT3/6, BT12 has been tested according to IEC 60601-1 and IEC 60601-1-2 by accredited laboratories and has shown full compliance to these standards and the standards listed in chapter 9 of this 510(k). BT3/6, BT12 fulfils only those parts of the standards ANSI/AAMI EC11:1991, and ANSI/AAMI EC38:1998 that relate to hardware requirements. In case the device is used in combination with appropriate software and the user manual is adapted to the standards, it is possible to completely comply with these standards. Since the BT3/6, BT12 is supplied without diagnostic/interpreting software, the manufacturer cannot claim full compliance to ANSI/AAMI EC11:1991, and EC38:1998. The software was tested as described in section 16 "Software". The corresponding FDA software quidelines were followed. ### 5.14 Conclusions Based on the above, Corscience GmbH & Co. KG concludes, that BT3/6, BT12 is substantially equivalent to a legally marketed predicate device and iffective for its intended use, and performs as well as or better than the predicate device. {6}------------------------------------------------ Image /page/6/Picture/1 description: The image shows the logo for the U.S. Department of Health & Human Services.
