Your problem doesn't sound normal to me, and I think you should discuss it with your doctor.  be sure to get the symptoms into a real context: what were you don't, just before, at and after the symptoms developed.  This includes what were you eating and drinking.  Were you physically active, or at rest... that sort of thing.

As for those out here in cyber-space, your description of "palpations" isn't specific enough to even try to relate to.  What is your normal resting HR, are the palps heavy but normal, or do they feel like they are "extra" pulses.
