My wife thinks i should see someone for my palpitations. should i?

Perhaps: If you're troubled by them, you should. If you have known heart disease, you should. If you're otherwise healthy and they you just feel an occasional skip or flutter, you're normal and don't need to bother. Everyone experiences palpitations sometimes and this may be made worse by nicotine, caffeine, stress, lack of sleep, or electrolyte imbalance from meds, diarrhea, vomiting, or sweating.

If they bother you: Palpitations are usually caused by extra heart beats, which all normal people can have. However, if they are associated with shortness of breath, chest pain, lightheadedness, passing out spells, they could be a sign of an arrhythmia and you should see a doctor.

Yes: If it bothering you enough for her to know about it , it should get checked out by a doctor.
