Diagnostic Efficacy of Connected WAtch ECG Versus External Holter ECG

Brief Summary

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.
