Kay, I don't like them, think they're horrible, too stressful to me -- just my opinion.
But I've had a couple many years ago that were with a treadmill and I had one at a year post-valve replacement that was evidently unlike anything anyone else here had ever heard of and was explained to me as a new technique at the time so I'll try to describe it: I was flat on my back but there was a pedal apparatus at the end of the table and I had to pedal for all I was worth, while they also simultaneously performed the echo. Exhausting. I could be wrong but I felt like it set me back physically so I've never agreed to another one.
During the last one my dad had, he "died" on the thing with some serious V-fib and V-tach and the cardios had to use the defibrillators several times to get his heart started again and they finally successfully got him going again -- Whew! That experience of his also probably contributes to my aversion to them.
