As many will know there are an infinite number of variations on intervals out there. As i stated before my time on a trainer is intense to the point that i am concentrating on actually keeping the pedals going and also not falling off the bike
. I dont get time to get bored as i am too busy looking forward to the next "rest period" which is usually zone 4 and not zone 5 (HR). 
I would recommend a HR monitor if you can but the "percieved effort" along with recognising your own breathing rate can be a viable alternative.
EDIT: Time spent on a trainer is generally more intense due to no freewheeling, stopping or climbing out of the saddle (usually) so you are pedalling constantly. Also extra strain is put on the wrists lower back etc as you are not stretching or generally moving around as you would on the road. This needs to be taken into account when planning sessions as it will take its toll on you.
