Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Recruit 50 participants (Intervention group) with atrial fibrillation (AF) where the onset is less than 24 hours before presentation to emergency department (ED), who are able to have delayed cardioversion in addition to standard medical care. These participants will receive at home monitoring of their heart rhythm with the Alivecor mobile single lead electrocardiogram (ECG) device. The participants will be required to record and transmit each single lead ECG every 6 hours for 48 hours. Participants will receive a text message and/ or phone call if a ECG recording is missing.
If normal rhythm is restored spontaneously within 48 hours, they will not be required to return to ED. The minority (31%) of participants with ongoing AF will be instructed to return to ED for a scheduled cardioversion.
In both scenarios, after the initial 48 hour period, the patient will be asked to record and send ECGs twice weekly, which will be reviewed by the research team. Four weeks later, they will have a follow-up cardiology appointment, either in person or via telemedicine.

Patients that have previously presented to ED with AF and were treated with cardioversion during the 12 month period prior to study commencement will be aged matched to the intervention group.

Outcomes
Primary outcome [1] 325114 0
Total number of emergency department time spent per visit for enrolled participants compared with historical age matched controls.
Timepoint [1] 325114 0
Four weeks after initial presentation to hospital with AF as assessed by hospital records.
Secondary outcome [1] 386893 0
Results of readings during remote monitoring period and need for repeat ED review. Results of readings are classified as follows:
o Reversion to sinus rhythm. ED review not required
o Possible AF, requiring ED review
o Uninterpretable, requiring ED review
o Unclassified, requiring ED review
The ECG's will be reviewed manually by the study physician.

Summary
Brief summary
The use of smart watch technology to improve the management of patients presenting with fast irregular heart rates (AF) in the Emergency department (ED). Participants will be given a Alivecor single lead ECG device to monitor their heart rhythm every 6 hours for the next 48 hours. If after 48 hours the heart rhythm has reverted to normal no further visits to ED are required.
If they remain in AF they will return to the ED for an elective cardioversion to restore a normal heart rhythm.
The aim of the study to the improve the management of these patients in ED and reduce the number of visits to ED.
