Overview

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.

Eligibility

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;
  • Refusal to use the watch provided for the study because they use a personal connected watch;
  • Unable to use the connected watch (lack of understanding of its use and rationale);
  • No smartphone;
  • Wearer of an implantable device (PM, ICD);
  • Already known and treated arrhythmia with identical symptoms;
  • Heart disease with indication for primary/secondary prevention implantable device;
  • Associated syncope;
  • Obvious extra-cardiac cause;
  • Pregnant or breast-feeding woman;
  • Inability to undergo study follow-up for geographical, linguistic, social or psychological reasons;
  • Participating in another clinical study which can interfere with this study
  • Patient under guardianship or deprived of liberty.

FAQs

Learn more about clinical trials

What is a clinical trial?

A clinical trial is a study designed to test specific interventions or treatments' effectiveness and safety, paving the way for new, innovative healthcare solutions.

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
