Indications for Use

The Samsung ECG Monitor Application is an over-the-counter (OTC) software-only, mobile medical application operating on a compatible Samsung Galaxy Watch and Phone. The app is intended to create, record, store, transfer, and display a single channel electrocardiogram (ECG), similar to a Lead I ECG, for informational use only in adults 22 years and older. Classifiable traces are labeled by the app as either atrial fibrillation (AFib) or sinus rhythm with the intention of aiding heart rhythm identification; it is not intended to replace traditional methods of diagnosis or treatment. The app is not intended for users with other known arrhythmias and users should not interpret or take clinical action based on the device output without consultation of a qualified healthcare professional.

Device Story

Samsung ECG Monitor Application is a software-only mobile medical app operating on compatible Samsung Galaxy Watch and Phone. Device captures bioelectrical signals via watch electrodes (wrist and top button) to generate 30-second single-lead ECG (Lead I). App processes signals to calculate heart rate and classify rhythm as AFib, sinus rhythm, or inconclusive. Data transmits to phone app for storage, display, and PDF generation. Used by patients in home/non-clinical settings for informational purposes. Output aids heart rhythm identification; not for diagnosis or treatment. Users must consult healthcare professionals before clinical action. Benefits include patient-initiated rhythm monitoring.

Clinical Evidence

Clinical study (n=544) compared Samsung ECG Monitor App to 12-lead ECG reference. Subjects included 268 AFib, 261 SR, 15 other arrhythmias. Primary endpoints: rhythm classification accuracy and signal quality. AFib sensitivity 98.1% (95% CI: 96.3%, 99.9%), specificity 100%. Inconclusive rate 2.9%. Cardiologist interpretation concordance 99.4%. Secondary endpoints: fiducial point annotation (QRS amplitude, RR interval, QRS duration, PR interval) met non-inferiority margins. Bench testing included IEC 60601-2-47 database testing, heart rate accuracy, and platform-specific safety/robustness testing.

Technological Characteristics

Software-only mobile application (SaMD). Operates on Samsung Galaxy Watch (Tizen OS) and Samsung Galaxy Phone (Android OS). Single-channel Lead I ECG acquisition via watch electrodes. Connectivity: Bluetooth/wireless transmission between wearable and phone. Software performs signal processing and rhythm classification. Safety testing includes electrical, thermal, and electromagnetic compatibility. No specific ASTM material standards cited, but skin contact safety verified.

Indications for Use

Indicated for adults 22 years and older, not previously diagnosed with other known arrhythmias, for informational use to record and display a single-channel Lead I ECG and aid in identifying atrial fibrillation or sinus rhythm.

No new safety issues were found during this testing. - . Clinical validation showing non-inferiority to the predicate in clinical performance in terms of - с ECG signal quality sufficiency - Rhythm classification accuracy o - Human Factors Validation ● - IEC 60601-2-47 ECG Database Testing ● - Heart Rate Accuracy Bench Testing - SW Verification Testing . In addition, testing was performed on the platforms, showing they meets all necessary specifications to safely and effectively host the subject SaMD. This included the following: - ECG Signal Quality and Lead Detection Bench Testing ● - Platform Interface SW Testing (for both platforms) ● - . Platform Interface HW Testing - General safety tests: Electrical safety, electromagnetic compatibility, radio frequency o emissions, material safety for skin contact, thermal safety for skin contact tests - Device robustness tests: Resistance to electrostatic discharge, water ingress and breakage o tests #### Clinical Study The Samsung ECG Monitor App was proven to be non-inferior to the predicate in terms of rhythm classification accuracy and ECG signal quality sufficiency. No adverse events were observed. The study enrolled 544 subjects, among whom 268 were AFib patients, 261 had sinus rhythm (SR), and 15 had other arrhythmias. The ECG App algorithm detection of AFib and SR was compared to cardiologists' read of 12-lead ECG reference strip. Among the recordings where the algorithm output a rhythm classification, AFib was correctly indicated with 98.1% sensitivity (95%CI: 96.3%, 99.9%) and 100% specificity (95% CI: 100%) in the Samsung ECG Monitor App, while the predicate showed 99.6% sensitivity (95% CI: 98.7%, 100%) and 99.6% specificity (95% CI: 98.8%, 100%) in the comparison study. As a result, the sensitivity and specificity of the Samsung ECG Monitor App were within the pre-determined non-inferiority margin, thus the primary endpoint was met. The ratio of readings that were deemed inconclusive (or unclassifiable) by the Samsung ECG Monitor App when the truth was either AFib or SR was 2.9% (95% CI: 1.1%, 4.7%) while the predicate was 2.2% (95% CI: 0.7%, 3.7%), which met the non-inferiority margin. To assess the signal quality of the ECG Monitor App recording, cardiologists' interpretation of the ECG Monitor App strips was compared to the paired reference 12-lead ECG. Cardiologists were able to interpret 98.5% (95% CI: 97.4%, 99.5%) of ECG recordings on the Samsung ECG Monitor App and 99.4% (95% CI: 98.8%, 100%) on the predicate App. The results showed good concordance between the interpretation of the ECG Monitor App strip and the reference 12-lead ECG, 99.4% (95%CI: 98.7%, {9}------------------------------------------------ 100%) on Samsung ECG Monitor App and 99.8% (95%CI: 99.4%, 100%) on the predicate ECG App. Both of the interpretation and agreement met the pre-determined non-inferiority margin. To further assess the ECG waveform accuracy, a total of 140 subjects (AFib cohort: 70, SR cohort: 70) were randomly selected for fiducial point annotation. Three blinded, independent ECG technicians marked the fiducial points for key ECG features (QRS amplitude, RR interval, QRS duration, PR interval) in comparison between the ECG Monitor App strip and the reference 12-lead ECG. The key ECG features of Samsung ECG Monitor App were all within non-inferiority margin with statistical significance. Thus the secondary endpoints were met. #### Conclusion The Samsung ECG Monitor Application is substantially equivalent to the Apple ECG App (DEN180044). The devices have the same intended use, the same key technological characteristics, and the same signal acquisition capabilities. In a clinical testing, the Samsung ECG Monitor app demonstrated that it is noninferior to the predicate in quantitative ECG measurement and rhythm analysis accuracy.
