Hello. Thank you for your question.
Neither calcium channel blockers or beta-blockers are rhythm control agents. They are strictly rate control agents. Your observation that you remain in atrial fibrillation for a shorter period of time may be a coincidence.
In general, paroxysmal atrial fibrillation becomes progressive over time. It sounds as if your "afib burden" is becoming greater. That is, your stay in afib longer and it is becoming more difficult to control heart rate and symptoms. At this point I would recommend you see your cardiologist for a new evaluation to include a history, physical exam, resting ECG, holter monitor (EKG monitor that measures rhythm for a prolonged period), and possibly an echocardiogram (ultrasound of the heart). You should also ask your physician about antiarrhythmic therapy (drugs that help maintain normal sinus rhythm). If drug therapy fails, there are invasive procedures that you may benefit from to decrease atrial fibrillation burden or to eliminate arrhythmia (in certain case of atrial flutter).
You say that paroxysmal afib becomes progressive over time. What type of time frame are you referring to?
The reason I ask this, is I was diagnosed with Paroxysmal Afib five years ago, and put on a regimen of 12.5 mg of Metoprolol once daily along with 5Omg of Flecainide twice daily. I have only had one episode of PVC's not afib in all this time. Am I to expect that this will not last?
What is PVC? I have AF and have had it since I was 19. My boughts usually land me in the hospital because my heart rate is so high. The only way out is meds in the IV until I convert, or once, cardioverted. Also, what is Paroxysmal AF?

hi pvc/pac are skips . flutters, paps of the heart
I was on a daily dose of the beta blocker (Metoprolol) for near lifetime SVT. My GP doc said to carry a small supply, and chew an extra 50mg when my SVT occurred (generally 4 to 5 times per month) as it MIGHT help. When I saw my cardiologist I mentioned this to him. His comment was (with a slight roll of the eyes) "It doesn't work that way". I still take it today (75mg per day) following a successful electrophysiology three years ago as it does a good, cheap job of controlling my borderline hypertension.
