Diagnostic Efficacy of Connected WAtch ECG Versus External Holter ECG (WAHOE)
Rentabilité Diagnostique Des Montres connectées Par Rapport au Holter ECG Externe Dans l'Expertise Des Palpitations Fugaces Symptomatiques Sans Documentation électrocardiographique Per Critique.
Palpitations are a frequent reason for consultation (16% of total volume) and management in the emergency department.
Conventional diagnostic management in our establishment is based on a 48-hour external ECG holter, combined with a stress test if symptoms are triggered by physical activity.
The diagnostic difficulty lies in the frequency and duration of this transient symptom. At the time of consultation, the patient is often asymptomatic. The initial strategy is to demonstrate an electrocardiographic trace during the attack, in order to adapt management to the chosen etiology.
The HOLTER ECG is the gold standard, but it is not very cost-effective due to the infrequent and random nature of the onset of symptoms.
The advent of accessible connected tools such as connected watches seems to be an interesting alternative for acquiring a per-critical trace of symptoms. They are widely adopted by the general population, with ease of use by the individual and long monitoring times.
The main aim of the study is to establish the diagnostic cost-effectiveness of one or other of the two diagnostic strategies (rate of identification of the causal arrhythmia) at 6 months from the cardiological consultation.

Description
Inclusion Criteria:
- - Any patient consulting for the main reason of "palpitations" without a previous diagnosis of arrhythmia, unless the current symptomatology appears different from that associated with the previous rythmological diagnosis;
- Palpitations requiring cardiological consultation or emergency hospital treatment;
- Absence of suggestive diagnosis on intercritical 12-lead ECG (pre-excitation, AVB M2/3, high-grade atrioventricular block, non-sustained tachyventricular, atrial fibrillation with heart rate > 110 per minute, atrial tachycardia or flutter);
- Non-contributory stress test (no electrical abnormality, occurrence of arrhythmia or reproduction of palpitations) if isymptoms occur during exercise;
- Accepts to wear the watch all the time outside the charging time;
- Using a personal smartphone or tablet compatible with the Health Mate application and with an Internet connection;
- Affiliated with a social security system ;
- Providing dated and signed an informed consent form.
Exclusion Criteria:
- - Refusal to wear the connected watch;

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: connected watch
All patients will be equipped by HOLTER for 48-hour monitoring, with an event form to be filled in, at the same time as receiving a connected watch for a 6 -months period.
They will be asked to record an ECG with the watch only when they experience symptoms that have included them in the study
|
All patients will receive a connected watch from the research associate, along with instructions on its usage and support for creating an account on the Healtmate application using an anonymized e-mail address. They will be able to transmit up to 3 ECG tracings deemed to be per-critical. A follow-up phone call at 2- months will assess understanding of the device and its proper use, as well as the occurrence of adverse events and compliance. |

What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Rate of diagnostic profitability of the connected watch compared with the conventional procedure (48-hour ECG Holter).
Time Frame: at 6 months or when the watch is returned, whether a diagnosis has been made or whether there have been 3 ECG transmissions that did not reveal any cardiac arrhythmia.
|
We will compare the diagnostic performance of the connected watch with the HOLTER ECG, by identifying a symptomatic arrhythmia, , in the purpose of a faster and adapted cardiological management.
|

|
A diagnosis is defined by the documentation of an objective cardiac arrhythmia (focal atrial tachycardia/atrial fibrillation HR >110 bpm/atrial fibrillation HR<110 bpm/atrial flutter/junctional tachycardia/sustained or non-sustained ventricular tachycardia/peak tachycardia/sinus tachycardia/ventricular fibrillation/high-degree conduction disorder) concomitant with the symptomatology motivating the initial consultation.

Confidentialité et protection de la vie privée : Le partage des données IPD pourrait compromettre la confidentialité et la protection de la vie privée des participants. Les données individuelles, même anonymisées, pourraient potentiellement être utilisées pour identifier des individus, en particulier dans le cas de petites cohortes ou de données sensibles.
Sensibilité des données : Les données IPD inclusent des informations sensibles sur la santé. Le partage de telles données est soumis à des réglementations strictes sur la protection des données et nécessite des mesures supplémentaires pour garantir la sécurité et la confidentialité.
Ressources et coûts : Le partage des IPD nécessite des ressources supplémentaires pour l'anonymisation, la gestion et la mise à disposition des données. Nous n'avons pas les ressources nécessaires pour effectuer ces tâches car notre budget est limité.
