- InterventionsRace-6 is an observational pilot study during 6 weeks, without a control group. The intervention deployed is a standard electrical cardioversion performed in the home environment of the patients. In detail: we will investigate the feasibility of home direct current electrical cardioversion (DC-ECV) in adult stable patients (n = 30) with recurrent persistent atrial fibrillation (AF). This is a prospective study of home-based DC-ECV using Corpuls3® equipment conducted by specialized emergency care practitioners (ECPs) after application of intravenous propofol for sedation. ECG before and after home DC-ECV procedure will be performed. Synchronized shocks of biphasic energy is applied by deployment of a maximum of four shocks of 200 Joules each with the electrode position placed at the anterolateral (AL) (= anterior-apex (AA)) site. Follow-up will be done at 6 weeks, comprising of telephone contact and, when needed, personal contact at 4 and 24 hours is conducted to monitor the recurrence of AF, complications and adverse events. In addition, the cost-effectiveness relationship of home (n = 30) versus a matched control group of hospital DC-ECV (n = 30) will be calculated. The total study is estimated to last 6 months.
- Primary outcomeIn this observational feasibility and safety study in 30 patients the
(a) feasibility endpoint is completion of cardioversion (% of study patients with a recurrence of AF in whom a home cardioversion is performed, i.e. to whom at least one DC countershock was administered while the patient was under deep sedation;
(b) safety endpoint: a composite of major adverse cardiovascular and cerebrovascular events (MACCE) occurring within 24 hours (subdivided in early MACCE, i.e. during the first hour observation period and late MACCE, i.e. thereafter up till 24 hours).

completion of cardioversion (% of study patients with a recurrence of AF in whom a home cardioversion is performed, i.e. to whom at least one DC countershock was administered while the patient was under deep sedation);
- Secondary outcomeA composite of major adverse cardiovascular and cerebrovascular events (MACCE) occurring within 24 hours (subdivided in early MACCE, i.e. during the first hour observation period and late MACCE, i.e. thereafter up till 24 hours). MACCE occurring during 6 weeks follow-up; any hospitalisation and all-cause mortality during 6 weeks follow-up; number (%) of patients in sinus rhythm at 1 hour in the post-shock observation period; idem at the end of 6 weeks follow-up; inventory of all interventions in the study related to cost-of-care.
- TimepointsThe primary endpoint will be recorded on day 1 of the study, i.e. the day of the DC electrical cardioversion.
The secondary endpoints will be recorded as follows:
- MACCE at 24 hours and at the end of follow-up after 6 weeks.
- percentage of patients in sinus rhythm at 1 hour after DC electrical cardioversion and at the end of 6 weeks follow-up
- the inventory of all interventions as well as study related to costs-of-care will be collected at the end of 6 weeks follow-up

- Brief summaryAtrial fibrillation (AF) is common daily practice in hospitals and is associated with significant morbidity and mortality. Its economic burden is high in the affluent countries. Direct-current electrical cardioversion (DC-ECV) is one of the methods to restore sinus rhythm in patients which usually takes place in a Cardiology Department. Nowadays prompt service is hard to provide in many institutions due to logistic difficulties around DC-ECV (shortage of beds, limited number of personnel, problematic control of the INR and workload of the staff).
The Dutch government tries to realize a shift in treatment of patients from the clinical setting to the primary setting. The focus lies on treatments that not necessarily have to take place in the hospital. A shift to the primary setting (i.e. primary care physicians, emergency care practitioners) is thought to reduce costs while maintaining high quality of care. In addition, (medical) care becomes more and more focused on the needs and wishes of the patient. Since January 2012 Emergency Care Practitioners (ECPs) are qualified (under certain conditions) to perform elective cardio versions.
The present pilot study is designed in order to assess both feasibility and safety of home DC-ECV in the management of recurrent symptomatic persistent AF performed by emergency care practitioners (ECPs). Cost-efficacy will also be analysed.
