Just a suggestion to anyone with AF. I've had Permanent AF for around 5 years but, thank God, I'm asymptomatic (at least for now), so it really has very little impact on my life.
One thing that I've learned and been surprised by how few people do it is that my doctor (the sainted Ben Brown at Wythenshawe) suggested that I switch from betablockers to calcium channel blockers. I cannot tell you how much of a difference it made to my life.
It's only my opinion but I think betablockers were leaving me with very cold extremities, listless, impacting on my ability to react to any situation and I think were making me depressed. Calcium channel blockers do none of that but they still control my rate (rhythm might best be described as Jazzy
If you feel that betablockers are draining you then have a chat with your cardiologist and ask about whether it's appropriate for you to have a trial of switching to CCBs.
The common reaction seems to be that many cardiologists don't really know about them. It also might not be appropriate for you - BB help with rhythm control, I'm only interested in rate control. But it's like night and day comparing the two drugs.
Best wishes for your health.
