Recently, I was diagnosed to have exercise-induced SVT (Supraventricular Tachycardia), which is not a worrying condition, after regularly strenuous aerobic exercise, e.g. cardio interval training. SVT is faster than a normal heart rate, which can be caused by overtraining and caffeine. It can be annoying, scary, despair and alarming.
Doctor advised me that I can continue exercising, and I can take beta blocker whenever I need it after sensing my SVT symptoms, but I think my SVT is quite mild. My beta blocker is nebivolol (NEBILET) which is a newer beta blocker, but appears to be very strong to suppress my heart. I know beta blocker can slow down metabolism, so that I would have to reduce my caloric intake slightly and to increase my training load if it is still tolerant with my SVT.
I expect I will experience an episode of SVT if I frequently work out for my cardio performance. I think my local gym does not give me a plenty of fresh air, so that it can harm me more than good, apart from weight training which would be less harmful to my SVT. If so, walking in nature would be much better, as it would simply be such a safer exercise and gives me a plenty of fresh air, which, I suppose, is very important for lungs function.
I am waiting to see an electrophysiologcal cardiologist for exercise stress test, at the moment.
I wonder if anyone here have had experienced SVT or any rapid heart rate conditions and beta blocker?
