Excercise Intolerance - Do Beta Blockers Help?

[Jules]

Have any of you noticed that beta blockers help with excercise intolerance? I have read several posts of people being able to run again. I can't run without getting light-headed, but am not taking any medications for POTS, as of yet.

Some say they do.

The things that have helped with exercise intolerance are:

A supplement called Gaba taken before exercising

Afterwards rebound symptoms: caffeine and licorice.

Saline vastly improves my exercise intolerance. Before saline I was having trouble just sitting - after it I was ready to take on a marathon

Medication has decreased my dizziness, and I am more able to exercise, because of that

In some ways beta blockers helped-- I was able to do more before my heart rate got so high that I felt like I was dying. However, the beta blockers keep me from exercising as hard as I would in the past or want to at times, because they keep my heart rate low enough that if I am really working out hard I can end up more dizzy because my beta blocker isn't allowing my hr to get high enough to catch up. For me to get my standing/resting heart rate to stay between 95-130 I have to take enough b.b. that it prevents my heart rate from going above 180 bpm or so. Yet, even working out at 180 bpm I rarely am working hard enough to be short of breath or have sore muscles-- but I will get dizzy.

Exercise is a slow process. Sometimes you can get away with pushing, other times you cant and that balance is always confusing for me.
