Not an issue at all @gloaming .

I have AFIB but does not last long. They give me a % number of impact in heart I assume. No one at Mayo Pace Clinic or EP ever say much about it as I don't stay in Afib.

I think me, not you, caused any confusion. I am just not knowledgeable enough on this subject.

@gloaming Far as I know they don't give out pacemakers or ICD defibrillators just for the purpose of controlling or eliminating A-fib or any other arrthymias, with the exception, as I understand it, when a person is in permanent A-fib and is symptomatic to the point where the A-fib affects the quality of life, and/or is associated with a rapid ventricular response which drives the heart rate up to unsustainable rates. At this point a kind of "last resort option" is to ablate the A-V node so it can no longer function and the electrical signals from the atrium can no longer be transmitted via the A-V node to the ventricles. A pacemaker is implanted to send the electrical signals in a controlled fashion to the ventricles. As I understand it, the person still has the A-fib but may not feel it as badly.

A defibrillator is generally implanted when a person has had episodes, or is at risk for ventricular tachycardias which may be life-threatening, or is at risk or has had cardiac pauses, arrests. A defibrillator is implanted to shock the person's heart in the event of ventricular tachycardias or sudden cardiac arrests, to restore the heart to a normal sinus rhythm. As I understand it, most cardiac defibrillators currently come with pacemaker functions as well, whether or not the pacemaker function is activated depends on the patient's needs.

Far as I know, having A-fib alone does not meet the American Heart Association, European Cardiac Society, or the Heart Rhythm Society guidelines for the placement of a pacemaker or ICD. These guidelines address symptomatic bradycardia as primary reasons for pacemakers. Although one of their criteria does include the necessity of taking medication that causes bradycardia to control a condition in which there is no substitute for this medication. That's actually an A1 classification, meaning that all experts agree that pacemaker placement would be expedient and helpful for such a patient.

And that said, I've learned that pacemakers, once implanted in a patient, can be used to suppress A-fib episodes by using "overdrive" pacing. The pacemaker would be programmed to raise the pacing rate to a higher rate, ( I think mine is set at 75) when an A-fib episode is detected, this is intended to stop the A-fib and it seems to work pretty well, at least I've found. This is most helpful for paroxysmal A-fib, but pacemaker placement would not be indicated for this reason in a person who just has A-fib.

Pacemaker monitor readings/reports have to do with the status and functions of the pacemaker and cardiac functions and responses to the pacing over the period of time covered by the report. The reports include the remaining voltage in the battery and time estimated to the end of service, voltage applied for each paced beat, information about the leads, average percentage of atrial/ventricular pacing, total number, times and length of time that arrhythmias such as A-Fib ( these are classified as "Atrial High Rate Episodes" ) have occurred. The cardiac activity is also graphed ( called EGMs) so an EP/cardiologist/pacer tech can see the type of arrhythmia may be occurring, can see if it's A-fib or a non-afib atrial event, which they refer to as SVT. The reports will also show the number of times, dates and times and other details when the pacemaker made adjustments in its pacing to accomodate particular issues such as arrhythmias, lead issues ( some of those are referred to as "mode switching") and much other data that I can't even begin to understand or explain!

The CHAD2S2-VASc score has nothing to do with pacemaker readings. Looking at the link in your post, you can see the points listed there are for the risk factors in an individual's medical history, including history of hypertension, diabetes, strokes, TIAs, thromboembolism, cardiovascular disease, age and gender.

I hope this helps!
