An atrial fibrillation episode that terminates spontaneously within seven days is best described as?

Explanation:
Paroxysmal atrial fibrillation describes episodes that come and go and stop on their own, typically lasting less than seven days. The defining feature is spontaneous termination within a short time frame. If AF lasts beyond seven days or needs intervention to stop (like cardioversion), it’s considered persistent. Long-standing persistent AF remains continuous for more than a year, and permanent AF is when rhythm control is no longer pursued. So an AF episode that ends spontaneously within seven days fits paroxysmal AF.
