The suggestion of checking your skill screen is decent. It does take a bit of time to go from battle to that screen and back, but it's totally doable. Another benefit is if you are in a dire emergency and have a level up available. When you pick a stat to increase(which you are forced to do in that case), all your stats get immediately topped off. It's like an emergency full heal.
That said, using the console is faster (in the sense you can immediately turn it on and off to pause and unpause the game) and technically more accurate, as is can show a couple decimal places versus just integers. Type prid 14 and hit enter. Then follow with the getav command(s) for the stat(s) you want to know. Those are getav health, getav stamina and getav magicka. I'm pretty sure 14 is the default code for your character. You need to hit enter after every command.
Don't know if you know, but the ?/ key is a shortcut to the skill screen. Mind you that getav commands will only show the current state of your stats, not what they would be when full. Maybe this doesn't really answer your question since you want to see current and total stats simultaneously.
