Comparison of QT Interval Readings Between Smartwatch Combined With Cardiologs Artificial Intelligence and 12-lead ECG

Comparison of QT Interval Readings Between Smartwatch Combined With Cardiologs Artificial Intelligence and 12-lead ECG in Subjects Hospitalized for Antiarrhythmic Drug Initiation and Follow-up

The WatchQT study will compare the performance of a smartwatch combined with Cardiologs ECG AI Analysis system in monitoring corrected QT (QTc) intervals with that measured on a manually read 12-lead ECG in subjects with Normal Sinus Rhythm (NSR) during antiarrhythmic drug (AAD) initiation and follow-up at the hospital.

The WatchQT Study is a prospective, non-significant risk, non-randomized, monocentric, open, comparative, concordance pilot study.

Under subject consent, subjects hospitalized for AAD initiation and monitoring will have smartwatch ECG recordings done simultaneously with 12-lead ECG measurements before and after drug administration twice a day, in accordance with the existing in-stay subject monitoring protocol.

Inclusion Criteria:

1. Subjects over 22, able and willing to participate in the study
2. Subjects who are admitted to the hospital in NSR or AF and are eligible for AAD (class Ia or class III) dose initiation or re-initiation.
3. Subjects having read the patient information letter and provided his/her consent to participate in writing, by dating and signing the informed consent prior to any trial-related procedure being conducted

Exclusion Criteria:

1. Subjects with Cardiac Implantable Electronic Devices (CIED)
2. Pregnant or breast-feeding subjects
