As a domain expert in cardiology, I can provide you with information regarding the treatment of atrial fibrillation (AFib), which I assume you are referring to with the acronym "fib."

Treatment options for AFib include medication, lifestyle changes, and in some cases, medical procedures. One such procedure is electrical cardioversion, which involves delivering a controlled electrical shock to the heart to restore a normal heart rhythm. This procedure is known as "shocking" the heart back into its normal rhythm. It's important to note that electrical cardioversion is a medical procedure that should only be performed by a qualified healthcare professional, and it is not something that can be done casually or without proper medical supervision. read more >>
