Nothing dangerous just because the heart is regulated it cannot keep up with the extra demand (for oxygen) on high cardio impact exercise, so you fatigued alot quicker. And this I found to be true, apart from the salsa dancing once a week, I had to quit the boxecise and circuits. I ditched the propanolol recently, and energy levels are (albeit slowly) returning. This is not to say it will happen like this for everyone.
