## Indications for Use

The telemedical system "sensor mobile" comprises the patient activated Tele-ECG device SM100 / vitaphone 100IR and the REMOS Receiving Software. The SM100 / vitaphone 100IR records and stores one-channel ECG episodes and transmits these data by means of a telephone or a mobile phone to a receiving station equipped with the REMOS Receiving Software for further processing.

## Device Story

Patient-activated, one-channel ECG event recorder; records 30-second ECG episodes via chest-placed metal contacts. Device stores up to three episodes; transmits data via telephone (FSK) or infrared (IrDA) to a central station. Operated by patients at home; used by clinicians at receiving stations. REMOS software at receiving station processes, stores, and converts ECG data into PDF reports. Provides clinicians with diagnostic data for rhythm assessment (sinus rhythm, atrial fibrillation, flutter, tachycardia) and pacemaker function monitoring. Benefits patients by enabling remote cardiac event capture and transmission for clinical evaluation.

## Clinical Evidence

Clinical testing performed on 80 patients with suspected or known cardiac dysrhythmia. 100 ECG examples were transmitted and interpreted. 98% of received ECGs were interpretable. Study demonstrated capability to detect basic rhythms (sinus, AFib, flutter, SVT, nodal) and identify pacemaker spikes and bundle-branch block patterns.

## Technological Characteristics

One-channel ECG recorder; bipolar recording. Materials: Makrolon 2458 (cover), 316L 1.4404 steel (electrodes). Power: 3V CR2032 battery. Connectivity: Telephone (FSK) and IrDA. Standards: IEC 60601-1, IEC 60601-1-2, IEC 60601-1-4, IEC 60601-2-47, ISO 10993-1, ISO 14971, ISO 13485.

## Regulatory Identification

A telephone electrocardiograph transmitter and receiver is a device used to condition an electrocardiograph signal so that it can be transmitted via a telephone line to another location. This device also includes a receiver that reconditions the received signal into its original format so that it can be displayed. The device includes devices used to transmit and receive pacemaker signals.

# 7. Operational Characteristics

The Tele ECG device "sensor mobile" SM 100 / vitaphone 100IR, manufactured by TMS, is capable of recording, storing and transmitting up to three ECG episodes of 3C seconds each. The "sensor mobile" SM 100 is placed on the chest for post-event recording. The device is patient activated by pressing the record button. The 30-second ECG is stored in the device memory for later acoustic transmission via telephone or mobile phone in form of digital data (FSK) or via infrared (IrDA) and IrDA-enabled mobile phone to a telemedical central station equipped with the "sensor mobile" Receiving Software REMOS. The transmission is activated by pressing the send button. The device does not impair internal pacemakers and implantable cardioverters / defibrillators.

#### 9. Substantial Equivalence

The technical specification comparison reveals no substantial differerence between the "sensor mobile" system and the predicate device and no differences which affect safety or efficacy.

These devices are patient activated Cardiac Event Recorders that sense ECG signals from the skin surface. The method of placing the device on the skin has been used successfully by Heart Alerts's PHD™ The use of FSK encoding for transtelephonic transmission of

digital data is also used in the predicate device PHD™. The method of obtaining the ECG signal via metal contacts is identical.

The usage of the SM100 / vitaphone 100IR is also identical to the predicate device. The operational details are identical with the exception of the possibility of infrared / IrDA data transmission of the SM100 / vitaphone 100IR.

The "sensor mobile" Receiving Software REMOS receives the digital ECG data via telephone line and stores it into a database. The receiving software is designed for automatic operation 24 hours a day. The ECG data will be converted to a human readable output in PDF file format with anonymized patient / user information.

In the whole sending and receiving procedure is no substantial differerence between the telemedical system "sensor mobile" and the predicate device. Both systems are designed for transtelephonic transmission and uses software on the receiving side for further processing of the ECG data.

## 10. Summary of Non-Clinical Testing

The system "sensor mobile" meets or exceeds the applicable requirements of international standards for ambulatory electrocardiographs and the safety requirements of IEC 60601-1 and its applicable follow-up standards.

Biocompatibility assessment was performed for any materials in contact with the skin of the user / patient.

# 11. Summary of Clinical Testing

TMS has performed clinical testing on the "sensor mobile" system. The system was tested with 80 patients suffering from different cardiac dysrhythmia or patients that are suspected of having cardiac dysrhythmia (patients subjectively feel palpitations or pauses). One hundred ECG examples of the eighty patients have been transmitted and interpreted.

98 percent of the received ECGs could be interpreted which can be rated as a very good achievement. Especially due to the technical recording, the basic rhythm (sinus rhythm, atrial fibrillation, atrial flutter, supraventricular (heart atrium) tachycardia, or nodal

rhythm) could be detected with all the ECGs.

Furthermore, the function of pacemakers could be checked. The pacemaker spikes imaging and the reply of these spikes in the atrium or in the ventricle is good. Another possibility was the determination of wide QRS complexes (in the sense of a bundle-branch block pattern) in ECG examples.

The device sensor mobile SM100 and the service meet clinical demands.

# 12. Conclusion

Through the data and information presented TMS Telemedizinische System GmbH considers the "sensor mobile" system as substantially equivalent to the previously discussed predicate device.

The operation of the "sensor mobile" system shows a safe and reliable means for recording, transmission, storing, forwarding and presentation of patient ECG parameters and no adverse health effect or safety risk to patients when used as intended.
