Question: are there different severities of afib?
Answer: There are several different types of A-fib, which vary in the length of arrhythmia episodes and in how they respond to treatment. Paroxysmal A-fib lasts for between a few seconds and 7 days, while persistent A-fib lasts for more than 7 days. Long-term persistent A-fib is continuous and does not respond to treatment.
