A Study of Prolonged Electrocardiographic Monitoring in Patients With Heart Failure in Sinus Rhythm or Atrial Fibrillation

A Prospective Observational Study of Prolonged Electrocardiographic Monitoring in Patients With Heart Failure in Sinus Rhythm or Atrial Fibrillation

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.

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

Inclusion Criteria:

1. Heart Failure
2. Treated with Loop Diuretics for at least six weeks
3. Willing and legally able to sign informed consent

Exclusion Criteria:

1. Myocardial infarction in the previous six weeks,
2. Implanted pacemaker, including cardiac resynchronisation device, or defibrillator
3. Already participating in an interventional randomized controlled trial assessing effects on morbidity and mortality (this study does not preclude participation in future clinical trials).
