![img-1.jpeg](img-1.jpeg)

Figure 2: Enlarged View of the Web Application

ScioCardio ECG Analysis platform provides beat-by-beat ECG signal processing and analysis, QRS detection, Ventricular Ectopic Beat detection, interval measurement, heart rate, and rhythm analysis. The backend application is established in the cloud and accessed through an internet connection and a web browser to perform ECG analysis and generate reports.

The ScioCardio ECG Analysis Platform's algorithm is designed for electrocardiogram (ECG) beats and rhythm detection and classification. The ScioCardio algorithm uses a combination of standard signal processing techniques, clinically established ruleset, and Machine Learning (ML) algorithms. It uses the ML components to classify QRS complexes into 3-beat classes (beat type labelling) and to detect atrial fibrillation (AFIB) in the ECG segments. The algorithm also uses clinically established rules to identify arrhythmias using heart rate and beat patterns. The ECG analysis platform uses standard signal processing techniques to filter out noise from the raw ECG data. The algorithms used in the platform are modularized based on the functionality and input dependencies.

The ScioCardio algorithm accepts input ECG data sampled at 250 Hz using Lead II electrode configurations. It utilizes bio-signal processing techniques, clinically established rulesets, and machine learning technology to achieve high performance. The algorithm uses supervised machine learning techniques for beat classification and AFIB

The subject device, ScioCardio ECG Analysis Platform, and the predicate device is software-based solutions designed for ECG signal analysis and arrhythmia detection to aid healthcare professionals in cardiac assessment. Both devices process, analyze, and display ECG data to assist qualified healthcare professionals or trained personnel in clinical interpretation; they do not provide diagnostic conclusions or active monitoring functions.

The subject device has the same intended use as the predicate device. Both device are intended to process ECG data to detect the presence of arrhythmias. These analysis outputs represent potential findings to be reviewed and interpreted by qualified healthcare professionals or trained personnel. The subject device and predicate devices both process and analyze recorded ECGs, with results that are stored, transferred, and displayed. None of the devices provide alarms or real-time patient monitoring.

The subject device includes all the analytical outputs of the predicate device and introduces additional analysis outputs within the same general intended use. The ScioCardio device's arrhythmia detection functionalities, like the predicate device, are prescription features. The subject device is indicated for adults aged 22 years and older, whereas the Cardiologs Holter Platform includes both adult and pediatric populations. This difference does not raise new safety or effectiveness questions.

Therefore, the ScioCardio ECG Analysis Platform has the same intended use and similar technological characteristics as the predicate device. Any differences do not raise different questions of safety or effectiveness. Performance testing confirms that ScioCardio meets its performance specifications and is as safe and effective as the predicate device for their intended use.

To ensure robustness and clinical relevance, additional testing was performed using standard databases referenced in ANSI/AAMI EC57:2012 and ANSI/AAMI/IEC 60601-2-47:2012.

Comparative performance analysis was undertaken for algorithm outputs common to both the subject and predicate devices. ScioCardio’s outputs demonstrated equivalent performance to those of the predicate device. The testing outcomes affirm that the ScioCardio ECG Analysis Platform meets its design specifications and intended use, supporting a conclusion of substantial equivalence to the predicate devices.

In addition, a human factors usability study was conducted in accordance with recommendations in IEC 62366-1:2015, “Medical devices - Part 1: Application of usability engineering to medical devices”, and FDA Guidance, “Applying Human Factors and Usability Engineering to Medical Devices”, issued February 3, 2016. The results of the study demonstrated that users can use the device and understands its outputs based on labeling, and further understand appropriate actions if symptoms are present, such as when to seek medical care.

The performance of ScioCardio, in terms of sensitivity, specificity and positive predictivity is provided in the table below.

The ScioCardio ECG Platform was clinically validated using a diverse, statistically powered dataset of 2,850 ECG strips from 2,146 subjects, representing the intended ambulatory use population. All targeted arrhythmias were well-represented, with case counts exceeding minimum requirements to support reliable performance evaluation.

The system consistently met predefined acceptance criteria for sensitivity and specificity across all claimed rhythm types. These thresholds were informed by internal validation, performance of FDA cleared predicate device, and high-quality literature benchmarks. In addition, positive predictive value remained consistently high across rhythm classes.

Performance consistency was also demonstrated across key demographic subgroups, underscoring the generalizability of the algorithm. The validation process was conducted in accordance with the principles outlined in applicable regulatory standards and guidance, including ANSI/AAMI EC57:2012 and IEC 60601-2-47:2012.

These results support a determination of substantial equivalence to the identified predicate device.

# 10. CONCLUSIONS [807.92(B)(3)]

ScioCardio ECG Analysis Platform has the same intended use as the predicate device, and any differences in technological characteristics do not raise different questions of safety or effectiveness. Differences between the subject devices and the predicate device have been tested to ensure that the device meets its intended use. The results of nonclinical testing specifically demonstrate that ScioCardio ECG Analysis Platform meets its intended use which is equivalent to that of the predicate device. Therefore, ScioCardio ECG Analysis Platform is substantially equivalent to the predicate device.
