About this trial
The purpose of this retrospective study is to evaluate the clinical performance of SMD-RVECG, an artificial intelligence-based medical device software that analyzes single-lead electrocardiogram data to predict the risk of atrial fibrillation with rapid ventricular response occurring within 2 hours.
A total of 348 eligible electrocardiogram datasets collected through VitalDB at Seoul National University Hospital will be included. Atrial fibrillation with rapid ventricular response is defined in this study as atrial fibrillation accompanied by an average heart rate of 110 beats per minute or greater for at least 30 seconds.
Eligible datasets will be classified as positive or negative for atrial fibrillation with rapid ventricular response. Two qualified physicians blinded to the software results will review the electrocardiogram data and relevant medical records to establish the reference-standard classification. The blinded electrocardiogram datasets will then be analyzed using SMD-RVECG, and the software-generated predictions will be compared with the reference standard to evaluate clinical performance.
Eligibility criteria
Qualifiers
Continuous single-lead electrocardiogram data collected through VitalDB at Seoul National University Hospital between September 1, 2022, and September 30, 2025
Participant aged 19 years or older at the time of electrocardiogram data collection
AF with RVR-positive group: atrial fibrillation followed by rapid ventricular response, defined as an average heart rate of 110 beats per minute or greater for at least 30 seconds, with available electrocardiogram data for up to 2 hours before the onset of rapid ventricular response and after the onset in accordance with the protocol
AF with RVR-negative group: atrial fibrillation without rapid ventricular response, with 3 hours of electrocardiogram data available before a selected index time corresponding to a similar time during hospitalization as that used for positive cases
Disqualifiers
Electrocardiogram data considered to be of inadequate quality because of noise, poor equipment handling, unclear signals, artifacts, or similar problems
Electrocardiogram data with signal loss of 5 percent or greater
Electrocardiogram data with a heart rate below 30 beats per minute or above 300 beats per minute
Data collected from a participant who was pregnant or breastfeeding at the time of data collection
