Overview
Brief Summary
It is an observational study in patients with heart failure investigating the incidence of arrhythmias using a wearable device which can monitor heart rhythm for up to 14 days. In addition to gathering routine clinical information, research assessments include a symptoms questionnaire and a corridor walk test. Patients will be followed for clinical events (interventions for arrhythmias, hospitalisation, death) for 1 year.
Detailed Description
due to the slow recruitment, on the one hand, and the fact that the preliminary analysis gave the valuable results, on the other hand, the number of patients was reduced from 400 to 100 and the follow-up from five years to one year

Outcomes
Primary Outcomes
Number of Participants With an Identified Dysrhythmia on Baseline ECG Recording
Time Frame: on enrollment
A dysrhythmia will be defined as either 1. Arrhythmia for which there is a Class I or IIa recommendation for treatment with medication or devices in ESC guidelines. 2. One or more of the following even if it does not otherwise meet guideline-indication for treatment: * Sinus bradycardia ≤30bpm for ≥one minute * High-degree atrioventricular (AV) block (3rd degree or Mobitz Type I or II) * Pauses lasting ≥3 seconds (either sinus or AV block) * Frequent ventricular ectopy defined as \>1,000 ectopic beats per day. * Ventricular tachycardia with rate ≥100 bpm for ≥5 beats.
Secondary Outcomes
- All Cause Mortality(1 year)
- Combined Endpoint Made up of Cardiovascular Mortality or Hospitalisation for the Management of Heart Failure/Arrhythmia or Implantation of Any Permanent Device Capable of Pacing the Heart.(From date of enrollment until the date of first hospitalization for management of heart failure/arrhythmia or date of implantation of any permanent device capable of pacing the heart or cardiovascular death, whichever came first, assessed up to 1 years)
- Cardiovascular Mortality(1 year)
- Total Number of Hospitalisations for the Management of Heart Failure or Arrhythmia(1 year)
- Total Number of Patients Implanted With Any Permanent Device Capable of Pacing the Heart(1 year)
- Implantation of Any Permanent Device Capable of Pacing the Heart(From date of enrollment until the date of implantation of any permanent device capable of pacing the heart, assessed up to 1 year)
