Hi everyone. I was diagnosed with paroxysmal atrial fibrilation around 2009/10, and put on Aspirin and Bisoprolol indefinitely. I am now 43 years old. For years it's just came and went, maybe every few weeks. Recently the nature of it has changed. I discussed this with my GP and all they did was up my dose of Bisoprolol. Could anyone please help with a few questions:
1. When I get an episode, I have always been able to convert to sinus rhythm on my own by going for a brisk walk / jog. Even just for 30 mins. This works 100% of the time. My cardiologist seemed surprised by this. Does this seem normal for AF?
2. Recently, I have episodes maybe every couple of days, way more frequently than before. Upping my dosage of Bisoprolol only made a temporary difference.
3. My triggers have changed. Before, they used to be lack of sleep, alcohol, caffeine, etc. Now I frequently go into AF straight after a meal, immediately while drinking a cold drink, and resting on my left side.
4. I am a frequent hillwalker / mountaineer. In the last year, its been almost impossible to do this, because I frequently find prolonged uphill walking gives me a really strange feeling, like I'm going to faint, and I feel disorientated, dizzy and sick, like I could collapse. I'm not exhausted or particularly unfit, but yet it feels like my body can't cope. Yet I can sprint along a flat path without problem. I can only think this must be related either to my condition, or the medication. This is particularly distressing for me.
I seem to have no luck in getting answers from my GP. I may have to go back to a cardiologist, but thought I would ask here first for any thoughts. Many thanks!!
