I thought I would start a new thread since sometimes I miss info in older threads, and others will do the same, especially if they have not posted anything on the older thread.
I saw the following in a 2007 study and found it helpful. If this information is true, it is hard to understand why an EP or cardiologist would not want to positively identify the type of AF the patient has before beginning any treatment. Maybe they do and I just got misdiagnosed.
Excerpts from a study done in 2007 (Remember this is a 2007 study. Much has happened with drugs since then. )
No particular predominance
Often in patients with identified heart disease
During daytime or diurnal (daily cycle), provoked by exercise or emotional stress
Preceded by tachycardia
Higher ventricular response rate during AF
Benefit from beta blocker and/or digoxin
Predominantly in men, age between 30 and 50 years
Patients without heart disease (lone AF)
Preferentially nocturnal, during rest, after eating or drinking
Preceded by bradycardia
Lower ventricular response rate during AF
Aggravation by beta blocker and/or digoxin
Digoxin, verapamil, sotalol, and flecainide are poor choices
Disopyramide and quinidine better
Propafenone not very effective because of beta blocking properties
Correct PV ablation is effective in curing paroxysmal AF. Different treatment for vagal and adrenergic.
Careful history-taking is important for accurate diagnosis and appropriate pharmacological and ablation treatment of AF.
Specific IKACh channel blockers may become the treatment of choice for vagal AF in the future. (KAC is supposed to be a subscript.)
