Brief Summary:
The main purpose of this pilot project is to measure the feasibility of conducting a randomized crossover study examining short-term changes in atrial fibrillation (AF) symptoms in symptomatic females and males with paroxysmal or persistent AF when they engage in a standard week of exercise (i.e. moderate-intensity continuous training \[MICT\] or high-intensity interval training \[HIIT\]) compared to a control week (i.e. no moderate to vigorous exercise over 7 days).
Detailed Description:
Exercise training (e.g. 8 to 12-week exercise programs) has been shown to improve cardiorespiratory fitness and QoL, and reduce atrial fibrillation (AF) symptoms and time in AF in patients with AF. However, regular exercise participation is hindered by patient concerns regarding an increase in AF symptoms and episodes during or following an exercise session. Patients with AF also worry about potential negative consequences of increasing heart rate during exercise. This fear may be sex-specific as females report more AF symptoms at rest, experience faster heart rates during exercise and AF, and report greater symptoms of fear/anxiety than males. How exercise acutely changes AF symptoms remains to be examined.
The main purpose of this pilot project is to measure the feasibility of conducting a randomized crossover study examining short-term changes in AF symptoms in symptomatic females and males with paroxysmal or persistent AF when they engage in a standard week of exercise (i.e. moderate-intensity continuous training \[MICT\] or high-intensity interval training \[HIIT\]) compared to a control week (i.e. no moderate to vigorous exercise over 7 days). As secondary outcomes we will explore sex differences in short-term changes in AF symptoms (self reported with a questionnaire) and AF status (device measured with a wireless four-finger AliveCor KardiaMobile ECG) when symptomatic patients with AF engage in a standard week of exercise (i.e. HIIT, MICT) compared to a control week. Results from this pilot study will provide novel insight into the typical acute response to exercise in females and males with AF, and will inform appropriate approaches for the conduct of a future larger trial. This work is key to informing practitioners and patients of the typical acute exercise response in the AF population with the goal of facilitating exercise prescription and participation.
