chemo before Sutent

I was wondering if any one started on a different chemo treatment before using Sutent?  I was to start treatment last week but because of a rapid heart beat and now I have to have radiation for a tumor on my windpipe I don't think they can use Sutent at this time.  They think the radiation will stop the rapid heart beat once the tumor  starts to shrink. Just hope they can start me on some kind of chemo to get this treatment  started that does not cause rapid heart beat until  they can go to Sutent once my breathing has improved. Has anyone had to have a tumor on there windpipe  treated?
