Description of intervention(s) / exposure
Our primary outcome is the impact of the COVID-19 pandemic on atrial fibrillation (AF) in patients with a permanent pacemaker (PPM) or implantable cardioverter defibrillator (ICD) in situ.

Patients who are connected to the the PaceMate remote monitoring service during the COVID pandemic will be included. Data from these patients is automatically collected routinely as part of the PaceMate remote monitoring database. All AF episodes occurring in PPM and ICD patients during the first 100 days of the COVID-19 pandemic in the USA will be included in the analysis (21st January until 29th April 2020).

For comparison, a 100-day Control periods will be included.
The control period is to account for potential seasonal variations. This will be the identical 100-day period, but one year prior. (21st January to 30th April 2019).
To allow direct comparison, only patients who are represented in both the COVID period and the Control period will be included in the comparison analysis.

The study will require no participant involvement. Patients will have their AF episodes recorded, as per usual, on the PaceMate database.

Not applicable
Comparator / control treatment
The control in this observational study is a time period prior to COVID-19.
Data will be collected from the Control period. All AF episodes occurring during the Control period (January 21st until April 30th 2019) will be included in the analysis. These data will be derived from the PaceMate remote monitoring database.

Outcomes
Primary outcome [1] 324108 0
Primary Outcome- the impact of the COVID-19 pandemic on the occurrence of AF.
This outcome will be measured by comparison of the number of AF episodes, and number of patients affected by AF episodes, between the COVID period, and Control periods.
The number of AF episodes, and the number of patients who experience an AF episode will be derived from the PaceMate remote monitoring database.
Timepoint [1] 324108 0
The primary outcome measure will be assessed daily during in each participant, during the 100-day COVID period, and daily during the 100-day Control period.
Secondary outcome [1] 383778 0
The impact of COVID-19 prevalence per US state, on the occurrence of AF in the patients receiving remote monitoring via PaceMate, in that state.

All US states in which PaceMate provides a remote monitoring service will be included in the analysis. COVID-19 prevalence rates per state, as of April 29th 2020 (end of 100-day COVID period) will be obtained from the US Centers for Disease Control and Prevention (publically available information).
Per state COVID-19 prevalence will be correlated with per state AF rates during the COVID period.
Per state AF rates will be obtained via the PaceMate remote monitoring database.
Timepoint [1] 383778 0
The secondary outcome measure will be assessed by correlating per state AF rates (assessed daily during the 100-day COVID period) with per state COVID-19 prevalence (measured at a single timepoint- on the last day of the 100-day COVID period (29th April 2020).

Eligibility
Key inclusion criteria

Minimum age
5 Years
Maximum age
No limit
Sex
Both males and females
Can healthy volunteers participate?

Statistical methods / analysis
Descriptive statistical analysis will be undertaken via Stata 16 (StataCorp LLC, TX, USA). Categorical variables will be expressed as a percentage. Continuous variables will be expressed as mean ± standard deviation. The primary endpoint of the study is the occurrence of atrial fibrillation in PPM/ICD patients receiving remote monitoring in the USA, via PaceMate, during the COVID-19 pandemic. The 100-day period following the confirmation of the first COVID-19 case within the USA (Early 2020) will be compared with the Control period (Early 2019). The number of patients who experienced a primary event during the Early 2020 period and the Control period will be compared using McNemar’s test. The number of primary events occurring during Early 2020 and the Control period will be compared via a poisson regression analysis, with adjustment for age and COVID-19 cases in the relevant state. A two-sided p value of less than 0.05 will be considered statistically significant.
