The latest connected watch models feature 2-electrode ECG recording. This single or six derivations can be used to derive a wealth of information about the heart's rhythm. The information that can be derived from an ECG recording with a derivation goes far beyond̀ simple differentiation between atrial fibrillation and sinus rhythm. In contrast, in various clinical situations, a tracing restricted to an ICD may prove falsely normal, wrongly reassuring a patient and delaying management. The primary objective of the study is to evaluate the sensitivity of ECG-1D or 6D recordings from a connected watch in measuring electrical parameters, compared with a standard ECG-12D, also to obtain a bank of tracings, to create and validate an artificial intelligence algorithm for the automatic analysis of ECG tracings recorded with a connected watch and also to validate the feasibility and sensitivity of recording an ECG tracing with a connected watch in children., conditionsModule conditions: Arrhythmias, Cardiac, designModule studyType: INTERVENTIONAL, phases: NA, designInfo allocation: NA, interventionModel: SINGLE_GROUP, primaryPurpose: PREVENTION, maskingInfo masking: NONE, enrollmentInfo count: 3000, type: ESTIMATED, armsInterventionsModule interventions name: Smart watch, outcomesModule primaryOutcomes measure: Comparison of electrical parameters measured using the 2 ECG methods: P-wave amplitude, primaryOutcomes measure: Comparison of electrical parameters measured using the 2 ECG methods: P-wave duration, primaryOutcomes measure: Comparison of electrical parameters measured using the 2 ECG methods: QRS amplitude, primaryOutcomes measure: Comparison of electrical parameters measured using the 2 ECG methods: QRS duration, primaryOutcomes measure: Comparison of electrical parameters measured using the 2 ECG methods: QT/QTc, secondaryOutcomes measure: Creation of bank of anormal ECG trace, secondaryOutcomes measure: Compare the diagnostic capabilities of an ECG trace recorded with a watch against the reference method, the 12-lead ECG, secondaryOutcomes measure: Validate the feasibility of recording and sending of ECG tracings with a connected watch at the patient's home, secondaryOutcomes measure: Validate the feasibility of recording an ECG trace with a connected watch for a child, secondaryOutcomes measure: Validate the sensibility of an ECG trace with a connected watch for a child, eligibilityModule sex: ALL, stdAges: CHILD, stdAges: ADULT, stdAges: OLDER_ADULT, contactsLocationsModule locations facility: Hôpital Haut-Lévèque, city: Pessac, zip: 33604, country: France, contacts name: Pierre BORDACHAR, role: CONTACT, geoPoint lat: 44.81011, lon: -0.64129, hasResults: False
