If the face of a "patient" was tied to his bed, and light wasn't changing, and there was no movement around (i.e. in ideal conditions), then yeah.
But in the real world scenarios you want to take a look at more than one pixel, and use the rest of the picture for noise reduction & calibration.
That is for heartbeat. But yes, with better spectral resolution you might get some other cool data.
But from a scientific point of view, you don't really need spatial resolution for the heartbeat example, though, do you? If you just spent the same amount of money on getting high temporal and spectral resolution, surely one could do very cool things with 'just one pixel', so to speak. Especially if you had say 16 different wavelengths, instead of just 3.
