I was diagnosed with Paroxysmal AF in March after going into AF while an ECG was under way. After a trip to A&E and to the cardiologist I ended up on Bisoprolol 2.5mg which has done a good job of reducing BP and steadying heart rate. However ectopics were still breaking through with the odd short rush of rapid beats and I didn't feel confident that another AF incident wouldn't occur. Things have steadily improved as I have identified and avoided the common triggers:
Coffee (massive trigger)
Stress
Alcohol
Chocolate
Cold drinks
A good 8hrs sleep a night also helps as does regular exercise - two or three 1k swims a week - which keeps weight and stress levels down. Healthy eating and not over eating is also important for me, lots of fruit and veg and not much meat. All very dull but seems to be helping to establish a stable if slow NSR.
