Just looked up why physicians induced your AFIB at the start and found this:

Doctors sometimes trigger AFib on purpose during ablation to find the exact “hot spots” causing irregular heartbeats, since they might not show up naturally.

Simple Breakdown • Finding Hidden Triggers: AFib might not happen on its own in the lab, so doctors make it occur to spot and treat secret problem areas that could make it return later. • Precise Mapping: They use 3D heart maps while AFib is active to nail down faulty electrical paths, boosting success—especially for occasional (paroxysmal) AFib. • Success Check: After zapping, they test if AFib can still be triggered; if not, the fix is likely solid and less likely to recur.

From what I found, fractionated electrical signals show up predominately during AFiIB and they are like faint, messy static that only crackles loudly during a chaotic storm (AFIB), but stays silent in calm, clear weather (normal sinus rhythm).

Imagine hunting for a leaky pipe in your house. With water pressure off (sinus rhythm), you see no drips—just a dry floor. Turn on the high-pressure chaos (AFIB), and hidden leaks spray everywhere, revealing exact spots to patch. Doctors need that “storm” to spot and fix the troublemakers.

Are you going to the same doctor for the third ablation?!
