Acute Responses to Exercise in Females and Males With Symptomatic Atrial Fibrillation

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).
