Atrial FibrillationPhase 4VITAPHONENCT03966976
Comparison Between "Conventional Monitoring" Versus "Monitoring Via Vitaphone" in the Detection of Post Ablation Atrial Arrhythmias of Paroxysmal Atrial Fibrillation
A Phase 4 study testing ECG monitoring & record and Conventional follow-up in people with Atrial Fibrillation, run by GCS Ramsay Santé pour l'Enseignement et la Recherche at 1 site in France.
Trial summary
Atrial fibrillation (AF) is the most common atrial arrhythmia. Ablation of AF is a recent technique, nevertheless, the success rates of ablation vary between 50% and 70% depending on the paroxysmal or persistent nature of AF. Read more about this study

About this study
Atrial fibrillation (AF) is the most common atrial arrhythmia. Ablation of AF is a recent technique, nevertheless, the success rates of ablation vary between 50% and 70% depending on the paroxysmal or persistent nature of AF. These rates are difficult to assess in routine practice because they are based on the recurrence of fibrillation.
The Vitaphone is a non-invasive device, with which the patient can record a single-track ECG as his or her symptoms take place. The plot is then transmitted via the internet to the centre, which can thus diagnose a relapse of AF.
The aim of our study is to correlate the rhythm and symptoms of 20 patients with Vitaphone 6 months after AF ablation and to compare them with 20 other patients receiving conventional monitoring.
Read the detailed description
Atrial fibrillation (AF) is the most common atrial arrhythmia in the population and its incidence will increase in the coming years. Ablation of AF is a recent technique, the efficiency of which has considerably increased in recent years. Nevertheless, the success rates of ablation vary between 50% and 70% depending on the paroxysmal or persistent nature of AF. These rates are difficult to assess in routine practice because they are based on the recurrence of fibrillation.
This definition of recurrence based on symptoms (palpitations, asthenia, fatigue, shortness of breath, malaise, precordialgia) is widely debated because some patients have asymptomatic AF recidivism, while others experience palpitations that are not due to AF.
In this context, studies have been carried out with electrocardiographic recording devices implanted subcutaneously. Given the invasiveness of this monitoring, it is not feasible in current practice.

The aim of our study is to correlate the rhythm and symptoms of 20 patients with Vitaphone 6 months after AF ablation and to compare them with 20 other patients receiving conventional monitoring.
This is, to our knowledge, the first non-invasive French study using the Vitaphone.

What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
ECG monitoring & recordDevice
This is a mobile ECG recorder that not only records short portions of ECG on one or three leads, but also stores, processes and transmits their data to facilitate the diagnosis and to confirm the occurrence of AF arrhythmia episodes by the physician.
Conventional follow-upOther
Conventional follow-up
| Study group | Role | What they receive |
|---|---|---|
| Vitaphone Arm | Experimental | Follow-up via VITAPHONE in addition to conventional monitoring. Receives: Device: ECG monitoring & record |
| Conventional Arm | Active comparator | Conventional follow-up Receives: Other: Conventional follow-up |
What is being measured
The primary outcome is the main question the study is designed to answer.
Recurrence rate of AF between 3 and 6 months
Atrial arrhythmia documented in each arm by either an ECG or Holter or Vitaphone between 3 and 6 months post-ablation of paroxysmal AF and validated by a cardiologist.
Measured: 3 to 6 months

Questions about this trial
What is this clinical trial studying?
A Phase 4 study testing ECG monitoring & record and Conventional follow-up in people with Atrial Fibrillation, run by GCS Ramsay Santé pour l'Enseignement et la Recherche at 1 site in France.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 5 inclusion and 6 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 29 May 2019. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in France. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 4 studies take place after a treatment is approved, to learn more about its long-term benefits and risks in everyday use.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
Contact Jean Francois OUDET (+33683346567 ext. +33683346567, jf.oudet@ecten.eu), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Recurrence rate of AF between 3 and 6 months (time frame: 3 to 6 months). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 29 May 2019.
