contro; afib with pace maker or oblation?

According to "Dr. Google," ablation is also done to correct electrical issues, but a pacemaker corrects both Afib/Aflutter and AV block. It also says that, in some severe cases, they're both used. It says ablation actually can cure issues by "stopping chaotic electrical signals from spreading." A pacemaker doesn't cure underlying arrhythmias but is best for severe heart block (which I have). I just learned a bunch!

@lak1967 Dr. Google is wrong if it claims that a pacemaker corrects AF and AFL. It 'might', surely, but just as often it doesn't. It depends on the patient's particular re-entrant circuitry. A pacemaker only works if it isn't being fought constantly by the AV node, so the AV node must be 'nuked' first....meaning ablated...to destroy its output. This leaves the SA node to do the usual signalling, while the pacemaker 'paces' the ventricles. If that signal is confounded by re-entrants, rotors, and foci that permit extra signals causing AF or AFL, they remain in place...intact. So it is only medication or an ablation of the rogue signalling tissues that will stop AF/AFL, and even then, as we know, it doesn't always work. Same for the pacemaker...sometimes its placement and working stops AF or AFL, but it sometimes does not.
