Official title
Collection of Synchronised ECG and PPG Recordings in Healthy Adult Volunteers to Develop and Evaluate AI Methods for ECG- Parameter Reconstruction From PPG (Focus: QT/QTc).
Overview
This observational study will collect synchronized photoplethysmography (PPG) and electrocardiogram (ECG) recordings from approximately 50 healthy adult volunteers. Participants will wear the Corsano CardioWatch 297-2 and a reference ECG device simultaneously for approximately 24 hours, including standardized activities and free-lining conditions. The objective is to generate a high-quality paired ECG-PPG dataset to support the development and evaluation of artificial intelligence methods fro reconstructing ECG parameters, with a particular focus on QT/QTc, from PPG signals. The study will also evaluate the feasibility and usability of the wearable monitoring system.
Detailed description
Wearable devices have the potential to support continuous physiological monitoring in both clinical and home settings. Although photoplethysmography (PPG) enables comfortable long-term monitoring, it does not directly provide electrocardiographic (ECG) information. This study aims to establish a synchronized dataset of ECG and PPG recordings that can be used to develop and evaluate artificial intelligence algorithms for reconstructing ECG parameters, particularly QT/QTc, from PPG signals.
Approximately 50 healthy adult volunteers will be enrolled in this single-center, single-arm observational feasibility study. Participants will wear the Corsano CardioWatch 287-2 together with a reference continuous ECG device for approximately 24 hours. During the study, synchronized recordings will be collected during standardized activities (rest, standing, and light walking) as well as during normal daily activities.
The primary endpoints include completeness of paired ECG-PPG recordings, synchronization quality, and the proportion of recordings suitable for QT/QTc annotation. Secondary endpoints include participant comfort and usability of the wearable monitoring system, together with technical performance measures such as signal quality, device connectivity, and data completeness.
The resulting dataset will support future development and validation of AI-based methods for ECG parameter reconstruction from wearable PPG signals.
Interventions
- Device Corsano CardioWatch 287-2
Wrist-worn wearable device used to collect continuous photoplethysmography (PPG) signals and related physiological data during the study. The device is used simultaneously with a reference ECG device to generate synchronized ECG-PPG datasets for AI algorithm development and evaluation. - Device VivaLNK wearable ECG patch
Continuous reference ECG device used as the gold standard for synchronized ECG recordings and QT/QTc reference annotation
Primary outcome measures
- Completeness of paired recordings, synchronisation quality (offset/drift indicators), and proportion of usable segments for QT/QTc reference annotation [Time frame: 24 hours]
Secondary outcome measures (1)
- Usability/comfort of Corsano CardioWatch 287-2 (questionnaire) and technical issue rates (e.g., sensor detachment, connectivity interruptions) [Time frame: 24 hours]
